In case anyone sees this Ontrack Disk Manager will allow you to get past the 528MB limit on an old BIOS by providing an overlay. I have 3 2GB partitions on my IBM PS/1 because of it. It works great and even allows for booting from CD and floppy with the overlay loaded.
Lovely. I've been trying to find a working first gen Pentium for years, but no luck yet. That big orange power button makes me all warm and fuzzy inside. Fantastic! I love that case.
If you want this to be as original as possible, then I have a tip regarding the power supply: Typically, the AT&T Globalyst systems of this era used a Tiger Lead Year unit. It's standard AT in its power connection to the board, but I believe it may also be somewhat proprietary with the fan because it plugs into the motherboard either to power it or control its speed, or that of the CPU fan (it's been a while since I've dealt with Globalyst systems, so my biological RAM is a bit fuzzy). They came in 150w and 250w flavors, depending on whether you bought a desktop or tower case. This is based on my knowledge of the next gen of Globalyst systems, the 620 and 630, so it may not apply to the 5xx series. However, I have seen Tiger Lead Year 150w power supplies in the Globalyst 520 (DX2-66) series in photos I've found, so I am guessing it would also apply to a 590.
You can easily work around the bios disksize limitation via a network card and xtide-bios. You can flash/burn it to a bootrom and use it to manage your ide ports. It'll detect the drive(s) without the help of the bios and works with larger disks.

That PC should be able to support up to 8GB of HDD space since it was sold with a 520MB IDE or 1GB SCSI HDD (both capacities are above the cylinder 1023 which is the old BIOS limit and within the cylinder 1024 which is the second BIOS limit with regards to HDD capacity, the cylinder 1024 is 8GB and 1023 is 512MB).
Great restoration - good to see such a dandy machine being taken care of. It seems like the oscillator, for the cpu, is socketed - if you feel funky you can change it to add odd clockspeeds via inserting new crystals. I had mine, Siemens based board with a Tseng4000, running at 40 and 75 mhz respectively. The Pentium 60 and the chipset worked like that(with added cooling of course) for a long time. Could you "-timedemo" demo3 of Doom Shareware1.9(screen resized to hud and 1 border) and post the results?
I recently discovered your TH-cam channel, and I have really enjoyed watching your videos. This one really brought back some memories. I worked at AT&T in New Jersey from 1995 to 2000, and I remember these computers. I actually still have the original bmp wallpaper file, and I thought perhaps you might like it to complete the look of your desktop. I sent it to you via email.
We used to use translation layer drivers for old bios on dos to go past the 508mb max. This was a lba driver or a ultradma driver. Wish I could remember exactly what to do but it was available.
This thing *REALLY* reminds me of a lot of NCR's systems. Wonder if there was any sneaky-butcher-style OEM badge engineering going on between NCR && AT&T?
AT&T acquired NCR in 1991, only to spin off the company as part of their trivetsture they announced in 1995, which saw AT&T Technologies (renamed Lucent Technologies), AT&T Global Information Systems (name changed back to NCR), and AT&T Communications. Over the course of fiscal 1996 the trivetsture happened, and personal computers were no longer manufactured by the NCR business unit, as they went back to focusing on ATM machines and the financial industry. Most unfortunate thing is, AT&T for decades was prevented from entering the computer/data industry in a 1956 DOJ agreement to settle a 1949 lawsuit, and it was agreed that the Bell System would stick to only the national phone network, and not market externally, computer systems for corporate clients, but could, upon request, do government sanctioned work. Another lawsuit filed by the DOJ in 1974 wanted to break up Bell again, and the suit was settled in 1982, and finalized on 1 January 1984, with the spin-off of 7 Baby Bells, and with the "New" AT&T retaining Western Electric, later to be renamed AT&T Technologies, and Bell Labs. The strange thing is, AT&T was desperate to get into the burgeoning PC market that was growing in the late 70's, and early 80. That is the reason why they wanted to just throw the shackles of that 1956 decree off them, and then be allowed to get into the computer market, which was denied them so long as they were the Bell monopoly. In hindset, after spending billions to be in the computer market post 1984, and the failed merger of NCR in 1991, they should have kept the Bell System together, and let the big boys like IBM do computers, and perhaps worked out licensing agreements for their UNIX OS to manufactures.
That's awesome .... I found this one totally by accident in this thrift store where it was just sitting there, abandoned, without PSU or power button :) From the styling of the case I figured this would be either a 486 or early pentium, as I didn't know the AT&T line-up at all ... So I definitely lucked out with this one. A very nice system. But still need to do that multimedia upgrade :)
Oh, I wonder if anybody knows if that lower 1/4 bay spot was used for anything. Usually things like that are for extra front ports, or buttons, or the like.
Iam impressed - normally when you bridge the power-on contact for a longer time a ATX power-supply should power-off again (as I remember from my mind) - or does it that only if you do press longer when teh button was released after power-on? or does the converter do some "magic"?
It doesn't work that way. Power-on button on modern PC is not connected to the PSU at all. It's just a soft button. Meaning that it is handled by chipset electronics and by the software itself (generates ACPI event on press). ATX power supply only cares if green wire is connected to the ground (black wire) or not. If it is, then PSU is on if it's not then PSU is off. BTW. there is a possibility for a computer to crash so bad that holding power button doesn't work anymore.
You have no need to connect these two wires constantly (IMHO it's even bad for the power supply). You can take out a small pin out under the spring of the switch and it will becoe a knob (not fixating) as it should be. Good luck!
TY for posting that, I was always under the impression that ATX used a momentary switch. I did not know those old, large switches were convertible, tho.
The original power supply of this pc does not classify as the original AT standard but belongs to the LPX (baby AT) standard. An AT power supply is what you find in an IBM PC AT (which is ca. twice as large and does not fit in this enclosure).
I was given one of these recently. I cant get it to clear the bios password and have tried all the tricks the internet knows of. Did you ever get a manual for that motherboard or notice any way to clear the bios password? thanks
Love these kind of retro machines, i curently restore an Acer V55la moterboard , socket 7 based Pc, Pentium 233 MMX Cpu.Next monday it will receive some upgrades and hopefully it will be ready to play some retro games. Cheers
I have this same computer still loaded with the factory options, but it also hangs at the bios. I can no longer boot it, it will not let me boot from floppy or hard disk. :(
On an AT power toggle you have 4 wires : live and neutral (these are always hot when the power chord is plugged in), and 2 AC wires that are hot when the PSU is turned on. In this case however I am using an ATX power supply with an ATX->AT adapter. On an ATX power the power switch is not connected to the mains voltage. The PSU only requires 2 pins to be shorted (typically by hooking up the power button to 2 pins on the mainboard. So in order to start the PSU, you only need to hook up 2 wires on the power switch (to short 2 pins) to turn the PSU on.
You had very luck on that power button.. I know these arent use to obtain anymore.. And it was behind the front bezel. Maybe its an idea to install an LBA card or bios eprom somewhere so the system will support bigger harddrives. If you dont need the eprom socket on the NIC card, perhaps you could there install that LBA bios to overcome that 512MB problem.

Very nice restoration ! Be careful with that PSU, it says it's "For Pentium IV" !!! I'm kidding lol. This reminds me my Compaq Deskpro 590XL which has a Pentium 90. Absolute cutting-edge for 1994 PC. It integrates sound, networking and SCSI ! Oddly enough it came with windows for workgroups 3.11 instead of Windows NT.
Throw a Voodoo 1 card into it and test it with some statically-linked Glide games! I've been curious for a while about the oldest CPU that can drive a Voodoo card. Obviously you need a PCI slot, but I've read that Voodoo 3D accelerators cannot run on 486 systems even though there were some later 486 boards made with PCI slots. Of course I'd like to test that claim too, but if that is true then this would have to be about the bare-minimum. All the Pentium systems I ever played with were using the more common Socket 7 platform so this is interesting to me, a Socket 4 CPU! Neat.
My first Pentium PC was a Pacard Bell PC Desktop Multimedia With 120 Mhz 16 MB RAM 1 GB HDD and later a Riva TNT Graphics with 16 MB it was a expanive Compute for this time. I had Windows 95 on it, later Windows 98 and never Windows ME :D Great Video, Thank you, and i like the Orange Button :D
Those were fun times ... actually busy with a 200Mhz MMX build and playing around with an assortment of 3dfx cards (voodoo 1 / banshee / rush / ....). Will feature some pentium videos soon as it will be nice to step away from these slow XTs and 286 systems I've been showcasing recently on the channel :) Fond memories of the Riva TNT period also ....
Is there a reason he should pronounce things the American way? I always pronounce Mach with an a like in "Mac;" I'm a native English speaker from the UK who has studied compressible airflow so I'm more familiar than most with the Mach number. If it's a particularly recognisable product then there is certainly a case for pronouncing it as it would be in its source country, but insisting that non-native speakers should use American pronunciation for everything, even if their existing pronunciation is perfectly valid in other parts of the anglophone world, is just cultural imperialism.
Use Ontrack or EZ drive for bigger hard drives
