- In this video we're going to be taking our HighScreen Intel Pentium 75 and see what kind of games we can run on it.
I don't think we're done with this one yet, as I would like to explore some CPU / graphics and cache upgrades as well ... I would also like to see what other non-game-software we can run on this thing.
Let me know in the comments what you think and what you would like to see in a future video.

I remember playing Quake in 320x200 on my Pentium 75 with 16 Mb of ram... Thanks for the video!
You’re welcome. Was fun to make.
320x240 to be exact.. that's how I played it on my 486DX4/100
@@mrbrad4637 Don't like to say this, but IMX, that will be super slow with Duke Nukem 3D. Even 320x240 was slow and jerky, IIRC! OTOH, it rocked on a Pentium 100!
@@mrbrad4637 No, probably was 320x200, that was the default resolution for the software renderer.(Mode 13h)
@@mrbrad4637 DOS was 320x200
Can't wait to see the difference when you add the upgrades 🙂👍
I started with the old office 386 from my father in early 1995 and got my pentium 100 in the summer of 1996... Can't remember when I got my 200mmx, but it stayed with me for a long time. Till I got a pentium 3 in 2004.
The rapid increase in performance was really breathtaking in these days. Now upgrading from a i5 4460 to a i7 10700 does not feel like the worlds that where between the machines from 20 years ago
I remember upgrading my dx4-100 with a p1-133 oh man those were the days. After that i OC'ed the 133 to 166MHz, then got a 200 and ended the p1 era with a 233mmx. After that I went straight to a p3-1GHz which I had for AGES!
I remember our first real family pc was a P3- 550
But I am not so Young 😃 bevore we had an upgraded 386 (40mhz) with later 8mb ram. Even played some 3d mechfighting on it and teste programming in qbasic
My PIII rig was also long lived. My mobo supported Tualatin so I had eventually upgraded to a 1.4GHz Tualatin, 2GB RAM and an AGP GeForce 6600 GT and it did fine with Windows 7 32 bit. Did great with day to day tasks until programs started dropping support for CPUs without SSE2. Didn't replace it until Sandy Bridge.
i went from the dx4-100 to a 233mmx to a 700mhz atlhon (which was faster than my friend's pentium 833), then 1ghz atlhon, 1.2, 1.4, 1700+ 2100+ and so on. the gaps were all very huge up until 700mhz, then they became kinda iterative.
Hearing the sounds again, seeing the games, makes my heart warm :) Thank you.
I remember when I was finally able to play NFS 2 SE! I also remember playing games all the time in really choppy framerates ahhaha We didn't have much money. I always had old PCs. Dad did computer work, as I said, but it was just a side gig. We lived in mouse infested dumps and lived pay to pay. I was lucky to have older machines because of trade ins for work. Built a gaming machine this past December, first time in 8 years since having built my FX 8350. I'd bought a house back in 2016 for 15k out in the country, so much of my money had been going toward getting a drilled well, engineering a sewer myself, getting a new roof etc. Lived with just power, no plumbing for almost 2.5 years. Now that all that is squared away, I was finally able to engage in the joy of building a new system.
When I was in computer education school back in 1994 we used IBM Pentium 75 thru 90mhz computers. We ran Win3.11 and WinNT351 and Novell Server. And did allot with this CPU. Then I got a job working at a BIG computer company in Silicon Valley and we used Pentium 100mhz CPU on everything from WinNT40 workstation and server. And it ran everything from Oracle database to HP Openview, to Clustering, domain server and file servers, etc. We ran our entire World Wide corporation on the Pentium 75 thru 100mhz CPU. We had an NT Network that span the entire USA, America(s) and some Pacific Islands.
The Pentium 75 was in my first home PC! My family bought it for Christmas 1995 when I was 15. Such awesome memories! Windows 95 was a big advance but also a mess and I ended up using DOS only in the end before stepping up to a P200 MMX. I still remember the hassle of installing the DOS drivers to make the sound work. Beside all the games mentioned by the OP and in the comments, I used to play Heretic, Hexen, Theme Park, Theme Hospital, Stunts (best driving game in years imho) on the P75. Duke Nukem 3D struggled to run smoothly at 800x600 (= slideshow) though the PC mounted one of the first 1-MB Matrox GPUs. Evidently 1 megabyte of video memory wasn't enough LOL! Ah, I also remember that the system had 8 MB of RAM and an 800 MB HDD. Both of the PC's I mentioned were thrown away but I still have the parts of the first PC that I bought with my own money in 1999: a P3 450 with a Voodoo 3 3000.
The last game you play is actually Microprose's Grand Prix 2 released in 1995, the older brother being Formula 1 Grand Prix , released in 1991. Btw, Formula 1 Grand Prix was released in some countries with the title of World Circuit.
I should have known. I was having doubts when I saw the 1992. Something didn’t add up indeed.
@@RetroSpector78 the content on this video is 10/10 nonetheless!
The original F1GP I had on my Amiga 500 in 1991, it was a slide show but playable. On 486 66 it ran flat out 25fps.
@@Imperious685 The very same happened to me with GP2. It was barely playable on my 486 DX2 66 but I could play it smoothly once I upgraded to the Pentium 100.
Grand Prix 2 was released in mid 1996. It was based on the 1994 F1 season.
At the time of the release there were very few PCs that could run the game in SVGA with all texture settings enabled.
Eventually when PCs were fast enough a second problem arose where GP2, since it was a DOS game, didn't support the newer audio chipsets. Also, newer PCs didn't necessarily have good video acceleration under DOS.
Lately I've found the best way to run GP2 on a modern PC is under DOSBox Staging.
Same here, looking forward for the upgrades! Great Video, brings back so many memmories :)
These Vobis Pentium 75 episodes were special to me, cause that's the first CPU i had in my very first PC. Before i was satisfied with playing console games on my SNES and Mega Drive. The P75 was soon replaced with a used Cyrix p-133 though. Then my ATI Rage IIc got a voodoo1 upgrade. My motherboard was a pretty horrible PCChips thing in a giant PC case someone had spraypainted red before i bought it. The total ghetto show *lol* I still have thr P75 CPU right next to me on a shelf in an antistatic box. Even though those PCs could only do a fraction of what's possible now, they were more fun to me than RGB light pimped monsters of today. Yep, I'm getting old *lol*
Very nice video, hope to see the next one about this machine soon. Thx!
RetroSpector78 I love your channel and graphics cards upgrades you dig out in the end, brilliant! thank you
Might do a follow up, but have an entire basement full of fun stuff. And also lots of donations I still need to go through.
I used to love playing Wacky Wheels with my brother (on another computer) via a serial cable!
Yeah early multiplayer games (serial / ipx / tcpip) would be a whole video in and of itself)
i love these videos about gear i grew up with .. :) .. we also had a highscreen computer, but it was just a 486 SX25.. but still a massive improvement coming from an 8 MHz 8086 ;D .. i attended the introduction show for the pentium processor at CeBIT 1993 .. it was a very exciting time when this thing came out! but pentium PCs were expensive.. so it was only in 1998 when i had earned my first own money to afford my very first own pentium PC, which was a pentium II - 233. i was almost only playing flight simulator, but i remember having some great fun playing GTA 1 which we saw in the video :D
This configuration is exactly how I’ve started my PC journey! Love it!
I’ve had the motherboard with the sound addon, which was awesome, due to its capabilities of playing sound through the PC speaker! That was cool!
Indeed read about that. Must have sounded cool.
Fellow Belgian here :) played GP2 and monster truck Madness on our pentium 1 200MHz. Even played rollercoaster tycoon at a friend on a pentium 90MHz :) it was kinda slow with lots of objects on screen but we didn't care back then
i like the point you make, that before it wasn't about achieving max framerate or details, but about the playability.
Looking forward to you making further videos with the various upgrades
Did this get any upgrades yet?
I remember when I got a PC fast enough to play Road Rash! I played the heck out of that. and Warcraft 1, 2, Starcraft 1, AOE, Total Annihilation, Doom 1 and 2, Wolf 3D, Duke Nukem, Redneck Rampage... man I could go on and on and on. Ahhhh the nostalgia!!
Whacky Wheels is something that hits all the nostalgia and childhood memory spots. I remember every little detail about that game. I had so much fun playing it as a kid.
Great stuff, I love how you take us on these journeys, like 1:28, clicking on ‘Details’ always felt like unwrapping a present. What did it find...? 😮 Yes, the Intel card! 🥳
Love hardware with built-in driver support.
Nice choice of games!! Really liked how you showed the dramatic difference in performance just from changing graphic modes
There were so many other good games I could show. Was also amazed at how fast my 1gig hard drive was filling up.
@@RetroSpector78 storage and memory are always in the way of machines of that era :/
Almost the same system I had and the games I played back in the day, I had the P100 non MMX and ran that Diamond Stealth card. Oh the memories.
Wacky Wheels at a LAN party in the mid nineties with an ‘el cheapo’ coax network…. Great memories!
Hehe … that might also be a fun idea for a video.
As always.. Excellent video!! it's nice to see that there's a lot of room for improvement with the system.. L2 cache, faster CPU & on the graphics area. I'm working on a similar system setup with a Pentium 90Mhz, so I'll be using your work as a baseline!! You can still get good deals/findings on a Socket5 or early Socket7 platform, if you are looking for an alternative to a 486 (very expensive lately), for later DOS / early WIN games.
Picked up over a dozen socket 7 systems recently. These are really common over here. Also have boxes full of motherboards I still need to go through. You need to get lucky with finding older systems. I once wanted to bid on a Siemens 486 system (complete system with monitor) and asked the seller what she wanted for it. She said she sold the keyboard (generic Cherry ps/2) separate for 90 EUR and asked if I was still interested in the computer. She only wanted 15EUR for the computer + monitor. Sometimes the market / prices are crazy.
Wow, first time I've seen Wacky Wheels on any retro PC gaming video. Wacky Wheels was my first PC game I played back in the day. Loved that game.
My first pentium was a NEC 100mhz which later I paired with a 6MB Canopus Pure 3D ...gaming heaven...smoked the consoles of that time!
I was playing most of these on a p60! So much nostalgia watching these old games with Doom 1993 being my altime fav game of all time. I was 13 when it came out so was playing on school computers. The IT teachers used to delete doom and then we would just reinstall it again lol
what a machine!!! :D Love it!
Nice video. Cool little machine. 3d acceleration extended the life of these older machines quite a bit. I remember running a first generation voodoo1 pass through card that was a pre production/ engineering sample. On a machine from this era also. The difference (when it ran) was jaw dropping. I had to epoxy heat sinks to it, and pointed a desk fan at it to keep it from locking up. Prior to that, NO gpu had heat sinking or fans. They just didn't exist. Same deal with overclocking. I added a 66mhz crystal to the motherboard on a 386 SX33. It booted and worked twice as fast. It generated a ton of heat. Heat sinks and desk fans to the rescue again. Lol.
Sounds like a lot of fun. The 75MHz might be a bit too slow for a Voodoo1. Think you need a 133 or 166 to really start benefiting from the voodoo.
I have the 100 MHz Intel Pentium in a Packard Bell Legend desktop/ mini tower. The Windows 95 start up chime always brings back memories of my childhood with such an underpowered computer (when it comes to Windows gaming in the mid to late 90s, DOS gaming was still quite good). I take apart the Packard Bell from time to time just to get a look at the processor, motherboard and daughter boards.
gosh I remember playing on one like yesterday and it's 25yrs ago already :-)
You played through all my childhood favorites
Your videos are awesome and your voice is so good to listen (I really like your accent)
Keep going with the excellent work, bro! I may not comment a lot, but I'm always here watching your content and giving my thumbs up.
Greetings from Brazil O/ ^^
Thx a lot. Appreciate it !
@@RetroSpector78 O/ ^^
oh man what a trip in the past! I actually played many games you show in this video, hours and hours spent playing, good times.... good memories... (love road rash!)
This brings back memories. I bought a Pentium 90 back in 1995, with IBM motherboard, to run OS/2 on. But I wasn't aware of the single-threaded input queue bug at the time. Non-IBM boards could be hit or miss with running the OS, but one errant driver or app would lock up the queue and give the impression of a total lockup. I'd stay with OS2 until 1997 and then went Windows NT 4, which blew my mind over its improved speed and stability. Full 32bit architecture... other platforms did full preemptive multitasking and using
Nice vid. I had Pentium 75 MHz back in the day and played most of the games presented in this video. One note - that's not F1GP (which was released in 1992 for PC), it's Grand Prix 2 which was released in 1996.
You're correct .. I thought for a minute you were commenting on my latest video where I did show the 1992 F1GP :)
@@RetroSpector78 Yeah, seen that - actually came here from that video. Nice content.
Cool! My oldest retro PC is also a Pentium 75 with a Mach64 VT2 :)
Screamer! Absolutely love Screamer, easily one of the best looking software rendered DOS games of all time. But it does require a pretty beefy PC to max out. I play it on my K6-233 MMX :)
Indeed .. will never run smooth on early pentiums. But even in vga mode with low settings it is still lots of fun once you figure out how to handle the corners
I can't help but smile any time I see NASCAR Racing being showcased, being a big fan of Papyrus Racing's history.
Also had indy car racing on there. And did not know they also did Road Rash.
I guess I was playing a lot of games back then. I had a 486 DX2/50 and got a Packard Bell Pentium 150MHz open box cheap so I connected the two and we had LAN games (like Doom, ROTT). Good times.
amazing. my first pc had a pentium 2 on a slot a, and a trident pci card, which wasn't a 3d accelerator, thus I couldn't play most of the games that required a gpu. when I was a little bit more older, I bought a pentium 133 with a 3dfx voodo, but I tried to make use of it as proper machine, not as an old vintage gaming machine. I'm all in on with the idea of swapping the processor on this board to one that has a faster fsb and adding a better video card!
Pentium 75 was my first PC! Built by AST. I remember setting up a network at home with my younger brothers and playing Quake Death Match in 1996🤪
Had the Nascar Racing on my 133mhz Pentium with a Matrox MGA Millenium GPU - it was the first an only game which took advantage of the 3D performance of the Millenium.
It was running in SVGA full details smooooooth :)
i remember playing colonization on my packard bell pentuim 75mhz in late 95 or early 96. one of the two. oh man im getting old. ;)
Alien Carnage, from Apogee
I hope to replay someday on a classic machine.
I remember many of those games back in my days of rocking a 486DX2-66 (it was the only 486 in the department building, the computer room was mostly 386 based, save for one Mac). Be fun to see those other cards in there. Also - what happens if you populate the empty chip slots in those graphics cards?
one of the things i want the most is to find my first pc again. it was a 486 dx4 100mhz with 8mb of ram (i upgraded it to 16) and some huge board that included a sound blaster, a modem and network, a 800mb drive and a 4x cdrom drive.
i really want to build the exact same pc i had then, software included. i made a batch file that ran from autoexec and showed a list of all my games showing shortcut batch files to them. it was such a cool time, i miss it.
i want to overclock the hell out of it to see what could have been. i heard those cpus could hit 186mhz stably. imagine that. so much suffering i'd have not went through...
Nice.
For me it was Mechwarrior 2
I played the hell out of that game back in the day
We made the big jump from a 386sx to a PII 233, but I remember playing Screamer for a long time. If the damn game didn't crashed so much. Doing championships needed to hope it would make it until the end
This makes me miss my first pc. AMD K6-2 with a SIS 530 onboard graphics chipset.
I was stunned how fast a matrox mystique is in my P75.
I wish there was a book on PC history covering say the 286 to the pentium 3 and showing what games were popular and playable at each stage and maybe struggles like mine, of trying to play newer games on older pcs. I'd write it myself if I could remember my childhood more hahahah. My dad fixed computers as a side job when I grew up in the 90s as a child. So from age 5 in 1990 to 91 onward I always had some older generation PCs which people would often trade in so dad could fix their newer computers etc. I had the 8088, 286, 386, 486, 486DX, pentium 75, 90 100, 120, 133, 166, 200, 233, 266, 300 onward. until the pentium 3 I got new as a teenager, I always struggled to run modern games on my older tech.
Good video
Around 1:25, you asked what that Wizard is actually doing. I'm here to tell you :)
The Wizard is scanning every bus address in the system recursively. Each time it finds a device at a bus address, it checks the vendor and device IDs against the Hardware Information Database in Windows. For each device that is a match, Windows will show it by name and help you with driver installation. Devices that are found but not immediately identified by Windows (doesn't match vendor/device ID in the Hardware Information Database), show up as an "Other Device" and would then prompt the user to install third-party drivers.
Hope this helps answer your question.
As I watch this video on my laptop a clone of my 1996 Tulip 486 with Pentium Overdrive lies ready to be assembled. I remember playing Quake with no problems then, will be fun to try it now
You should do it. Had lots of fun with this one.
My God! F1GP, Jean Alesi on Ferrari at old spa circuit, LOVE IT!
Yeah it was lots of fun. Played it a lot on my first PC (486dx2 66)
@@RetroSpector78 my very same pc I loved it to distraction (and destruction :D)
Wonderful video! I really enjoyed watching it! I wonder why CPUs were made with ceramic back in the day?
Maybe cheaper then gold top, and better heat dissipation for lower costs to produce? (ceramic cheaper then gold)Plastic is not a very heat conductor.
I was playing starcraft 1 on a Pentium 75 with like 16Mb ram or whatever in the late 90's . It was terrible, but it played, and I was able to play reasonably good by myself.
very cool PC
In addition to the upgrades mentioned at the end would also like to see if the P75 can handle a fsb increase for an overclock. Also how well does it work with a 3dfx voodoo1. Back in 1996 I upgraded from 486 dx2-66 to P133 so never experienced a slow Pentium.
Will see if I can do some overclocking. It is definitely held back by the lower fsb.
I can remember upgrading my system multiple times to get Nascar Racing to run with full SVGA detail.
what where your system specs back then?
There was a pentium 100 that made use of the 50mhz bus on socket 5 with a 2x multi. Though I think it was embedded laptop only. I remember seeing it listed on intel Ark some time back. How prevalent it was, I have no clue. I can't imagine it was all too common. I have never seen one in the several p100 laptops I have used over the years.
"...the game itself was superior to the fps..." best quote ever. thank you. i remember me play GTA on a 486DX-40 with the lowest settings and i just didn't care about fps...
Yep, it was like that with many games. We just didn’t know any better and it was that ignorance that made it fun.
I remember adding a COAST module with 256kb of cache to my P133 system and it made a massive difference in MechWarrior 2 at the time, would be interesting to see what happens with this P75.
Always heard that for msdos gaming performance the l2 cache doesn’t make a big difference. But never really tried it.
@@RetroSpector78 if it makes difference for DOS benchmarks - it definitely does for DOS games
hi mate, awesome stuff! I really enjoy these intel mainboards, the endeavor is a great piece of hardware for a non mmx cpu! is there a follow up to this video, where u did add l2 and maybe another graphics card, for comparison? cheers!
Looking back, I can't believe I used to play Quake 2 on my Compaq Deskpro 575; 75MHz with 32MB ram lol
What you had was what you had I guess, better then nothing.
My pc was a Pentium 75 with S3 1MB video card + 32 MB EDO ram. Only software render was available.
I was playing dos games under Win95 like DOOM 1-2, Duke nukem, death rally, warcraft, KKND in 320x200 resultion NFS 1 was also dos based. I remember playing Age of Empires 1 in 640x480 and Diablo 1. Later I tried NFS3 in sw rendering and low resultion, but without 3dfx card a Pentium MMX 200 was also not faster. The Voodoo or Geforce 2 card was that time a real upgrade to play with NFS 3 and above, Unreal Tournament, Deus Ex etc.
I remember many years later I got an "old" dual pentium pro 200 computer (was a workstation). The dual pentium pro was fast, with a lot of L2 cache, but lacked the MMX instruction set. I remember that I could not play any avi video in VLC. Later I figured out, that I have to download some earlier VLC version, and switch off the MMX, SSE and all the multimedia instructions in the expert settings. After this I could watch a AVI video.
I bet on S3 trio64v+ VBE/Core 2.0 for Ultimate DOS experience. Regards
Nice
holy shit, my uncle had that Nascar game on his computer. instant nostalgia
I'd like to see you max the thing out!
neat vid
6:06 that's about how well my computer ran this game in regular VGA mode lol. Not sure if it was a pentium or 486 though. I was really young. Also had no sound because I don't think it had a sound card.
On the brightside, No soundcard does win you a couple of fps :)
I wanna play some old games on a CRT one day, I dont have much experience with that and I just dont have the space for a setup like that
Cant get over how good F1GP looks in SVGA for 1992!
Because it was released in 1995. My mistake. Sorry about that.
@@RetroSpector78 Ah that makes more sense! Its not a game I am familiar with but I might try and track it down now.
@@ljrretropcs it’s a true classic. Lots of fun.
I had a Pentium 75 in high school that I overclocked to 100. Paired it with a Rendition Verite 1000. It could play many early 3d games reasonably well, especially if they had a version specifically for verite cards. I believe Myth and Quake both ran and looked quite well.
Perhaps I should attempt an overclock yes. Stop putting ideas in my head :)
Also have a verite card. Might pair it up. Didn’t nascar racing also had a version for that ?
But can you get Screamer running in SVGA high settings properly without changing the motherboard? Only the CPU, GPU and RAM.
Hi there, I've been on the look out for some nostalgia. My dad owned a Tiny Pentium 75 back in the 90's. Over here in the uk, there were 2 companies Tiny and Time. Both have disappeared and theres little information about their computers online. Where would I find out about these old systems, and even possibly owning one?
I had some 486 dx2/dx4 can’t remember the current model .. got creative cd rom 2x that was legend 😅
after that got pentium 100 I guess
My uncle had 386 33mhz with turbo bottom 😂 I remember I was playing “desert strike” on it was amazing 😆
ET6000 FTW!!! I had that card, blazing fast 2D due to big memory bandwidth (128bit memory interface).
Never used one. Wonder how much of a difference it will make.
@@RetroSpector78 no 3d support, it's faster than many other 2d card, maybe the faster.
We played raptor with I think mouse support an a 386 with 40mhz... Installed it lately via dosbox.... Mmmh forgot to play it.
The Raptor actually runs well even on a 33 MHz 386DX. I know coz I played it yesterday on my 386. :)
I think the resolution didnt seem so bad back in the days was because they were played on a crt which seems to make lower resolutions look better/smoother.
Good ol' German Vobis craftmanship. :D
I find it pretty amazing what is able to run on a 75mhz cpu. Another game that will run on a Pentium 75 is Sierra's Driver's Education 98-99. You have to turn the graphic details down but it will fine. If you have a Voodoo card it runs pretty good at 640x480 in glide mode on a Pentium 75.
Can it run Project Cars 2? The first pentium computers I remember were the 900s which were probably advertised in magazines around the time I was thinking of getting a computer for the first time.
Watching this video makes me realize that I valued the games that actually ran on my 486DX2 and later P200 MMX way too little as I always wanted to play the newest games.
A shame as today I'd know a ton of fun games to play with those vintage machines.
Yeah, we were always focused on the next new thing, unfortunately.
We missed a lot of fun by focusing too much on the hardware as well.
It is nice that with products like dosbox we can still run these games. And platforms like steam / gog also offer some retro games (albeit slightly more recent than the ones shown here)
Those were sold by Vobis, I played mainly Falcon 3
That PC is rather capable :)
Need to connect the power LED on the case... or maybe it burnt out :)
My system around that time was P133, 32MB, Matrox Mystique 4MB and SoundBlaster 16.
You are good
My first Pentium machine, running Diablo to death!
Well, I had a 486 DX2-66 back then, and yes, you can run games like Sim City 2000 or Doom 2 nicely on it, but only until end game. I remember being in the last level of Doom 2 and it was just a slide show, not playable anymore. What I would have given to have a Pentium 75 back then.
Never even had a classic Pentium myself, just a MMX 166 :)
A pentium 100 on a decent motherboard is usually the first machine I tell people to go and find if they are looking for a cheap retro machine. As they cover a wide swath of software. And can play the performance sensitive games by disabling L1 cache and playing with the timings a bit. They are generally far more plentiful than 486's, and PCI implementation is far more polished and can take a wider variety of cards.
The one I have is a slightly later model p100 on an Asus VX97, and interestingly its multi isn't locked to 1.5. I can also use the 2x multi, and finding the combo for 83mhz bus i can push it to 166 pretty easily. It doesn't have UDMA IDE like the TX chipset but this also makes it a little easier to setup windows 95A on it. And it also performs like a champ under dos/win3.1. As memory configurations in UMBs seems pretty much identical to a 486 but for a loss of 8k for a triton chipset specific block.
The 75Mhz Pentium was a second generation, released as a value PC. A Pentium 90, 1st Gen is significantly faster.
Yes it is held back by the 50mhz bus speed. Can imagine everything goes a bit faster if you have a 60/66mhz bus.
@@RetroSpector78 That can explain, for the graphics, why it seems not faster than a 486 DX! With Pentiums that I can remember, they most likely were all at least 60 Mhz, for the bus.
@Patrick Randolph IIRC, I remember one day in 1995, IIRC, (when I was 14, IIRC) when I found out a person got a Pentium 75 system, while I was broke and hardly knew a thing about computers! I ended up feeling yucky, because I didn't have the money!
1:20 What that routine does... Basically it tries to poke known hardware commands to a known list of port and memory addresses, in order to detect non-ISAPNP hardware (jumper configured or with propietary non-ISAPNP software configuration, like AWE soundblasters and the EtherExpress you have there).
This ofc has a lot of downsides, like certain hardware wouldn't like the way you poke in their addresses (or poke it wrong) and make the machine crash (hence the big WARNING in the Detection Progress dialog). This also has the downside it only can detect a predefined known list at time (MS HCT approved) so it would fail with later non-PNP hardware pieces (Serial hardware/later modems for example), or rare cards (like some National Instruments VXI-isa hosts). In this case, you have to go with manual add-hardware configuration wizard.
I recently got Pentium 75 recently and it is fun system to play with but not really to play games on ;)
