Hey Steve, Unrelated but do you remember what you had to do to get your Superbook Battery to work again? I saw your post on vogons and was hoping you could help fix the thousands of these that are still in the wild.

Very nice project! Another PS/2 saved. I'm currently working on something similar only mine is a regular small ATX PSU.. Those Italian PSUs in these Greenock Model 70s are the worst. They literally all die! The Astec units in the US M70s are way more reliable.. I would get rid of that big 10 ohm load resistor. It doesn't do anything but just heat things up in this case..

Wow. AXIAR stepping? I don't think I've seen that so far, usually only AXIA. I plan to do a few SktA builds as well... hope I can gather the final two missing pieces to close the gap across the 462 Athlon generation.

This is totally awesome! Your video proved that this can be done. Thanks for sharing... I have been trying to find P75 for myself for this upgrade but have had difficulty finding one. ;) If you ever have too many of these and want to apart with it, let me know. ;)

Mine works fine but something is rattling in it after i dropped it. Took it apart so far...then got scared to go further incase I couldn't get it back together. I'll give it a go and let you know how I get on. Thanks for the video....brilliant.

Kitty!!!

I really thank you for this video, may I know how to display the screen on a secondary screen? I have connected vga to hdmi but nothing appears... Can you help me with that?

Yeah, the Xeon is going to blow the QNAP away just on I/O capabilities. Time to invest in your lighting tho so it doesn't look like the video was recorded on a potato. And of course once you go 10GbE you never go back - best thing ever for a home network and much better than LAG.

Miniscribe 8425S. A very popular SCSI drive at the time. Not the best drive of the period but it does have onboard diagnostics...and it's self-parking (it parks after initalisation and when idle for a pre-determied period). This was the first drive in my Macintosh SE but it was later replaced with a Conner CP3040A with System 7.5.

this is waaaaay older.... 20 years ago, we have like AMD K6 or something....

You can put links download?

I can't even figure out how to get a monitor hooked up to this, lol.

I work a customer service job that still uses an AS/400 platform for one of our critical systems. If it isn't broken, don't replace it!

I cannot thank you enough for doing this! What a puzzle! I got one for 9 bucks on ebay and it needs new battery. I am really happy i found the video because the speaker is such a random item for someone to post. Kudos and subscribed. Ty

What is the connections for the db25 wiring to avoid the password?

really cool

Spending free time to “play” with an as400 is such an oxymoron. That machine is the manifestation of frustration and rage. Someone has to develop a system that is more modern and more reliable than AS400 ASAP!!! So finally AS400 can go extinct.

@13:42 What is that, I have one too but no idea what it could be for. Cds too big to fit in it.

Hello, can yoi suggest me a ISA/PATA CF card?

Removing the plasma screen from a scarce p75 would have to be considered a felony, it is difficult for me to understand why someone would go to so much trouble to ruin what makes that computer remarkable

My childhood pc. Wow

inches?

I cut my I.T. teeth on AS/400 (iSeries) and I'm jealous that you have one at home! :) Not that I have a ton of use for one, but it would be super nostalgic to have one. Enjoy learning (I know this is nearly a year old now).

Just so you know, manufacturers like PCBWay now offer custom flat flex. That would be super easy to recreate for not a huge amount of money.

What a cool machine this is!

Wonder why the floppy drives die on these things, I couldn't personally save the one on mine though I still have it stored somewhere. Modified a newer PC drive so that the original cable worked but the button didn't line up and it wasn't a very good fit. Later on I put a Gotek into it and since it needed 5V I just ran a USB cable through the back and power it externally but I do wish to eventually find a 5V source from the P70's own power supply or just a better solution in general. Annoyingly I last tinkered with it like 5 years ago so I don't remember much about what I did but they're such cool machines 🙂 Looks like there's an McIDE card these days that should help using other kinds of drives or CF cards whenever these original drives die and become impossible to find, really glad to see people are keeping these things alive. Also people are making replica MCA sound cards as well which is fantastic because the P70 definitely deserves a sound card, even though OPL2LPT works fine as well

"Unobtainium" : A lot of things like spares for GoPro or Caps for your Binoculars are become like this now in Ireland.

Was this intended for rack mount?

Oh my gosh, back in 1995 I worked at Big Lots (American closeout/overstock store). We got like 20 of these in one time (back then Big Lots actually got pretty random stuff in from time to time). I remember looking at it and thinking this was probably for banks or POS systems or something. I felt bad for the customers furiously trying to buy these because I felt like they weren't going to do what the customers thought they would...

I got one of my 'E' with the PCMCIA adapter running tonight - I'll need to figure out the Token-Ring PCMCIA drivers for Windows for Workgroups 3.11 next (it works with the Ethernet 3C589D PC Card).

oh that keyboard is sooo sweeet 🙂

What a random little machine. I'm guessing the E standards for embedded? I can't think of another better term that's associated with computer form factors. Nice to see the traditional black PCB from the era. Would be nice to see this fully loaded with PC card niceness like 802.11b wifi, external CD-ROM and a sound card, though the latter are somewhat rare. Quite the IBM collection you are building!

The riser adapters are just a connection that isn't microchannel, as that has many other factors to make a microchannel system. The same 'planar' for the PS/2 'E' was used in the very uncommon 9535 (Model 35 SLC2) and 9540 (Model 40 SLC2) where it had more room for expansion without using the delicate laptop ribbon connections. It is an IBM 486SLC2-50 CPU (and underneath the coprocessor socket is a connection for the 486SLC3-75 daughtercard upgrade that the 'E' doesn't have room for. You spotted the unpopulated onboard SCSI, and the 'E' has XGA-2 video; Overall, the 'E' strikes at the IBM notion that the ISA models should be less powerful than microchannel, but it would have been nice to have SCSI there too.

It reminds me a little bit of the Apricot Lan Station range of mini PC's - just not as flat!

Can you explain how did you remove the top cover/screen assembly? I see you just push it down, and in the manual says it comes all together, but try as I might, It won't come out from the back. The manual mentions six latches, which I have been unable to locate, and are on a part that lifts anyway (is only the very back who stays on, like if screwed)

it brings back the memory of the good old days.. I am not going well along with the newer technology ... lol ..

Amazing work！haha What a retro project!😃

Can you scan your IBM Tour Guide and Staring Guide to please all worldwide PS/1 users? 😀

Nice video thanks for making the video

Promo`SM 😍

nice piece :D i have my coolection this pc thinkpads series all 8 type of 755 thinkpad :)

Sweet looking rig - I also had an IIyama and it rocked picturewise.

Would be great to get a PC Card joystick port for mine.

What type of display cable did you use? Im about to get my hands on one

Amazing job, with VGA this machine "shine" really great!

nice mod, looks factory, i would put some hot glue in a few places to keep that panel secure, it can be easily removed with some alcohol if required

Very interesting video! curious do you have a new floppy drive? i’ve been struggling to find one which will accept the eject button, for my p70 ive got a modded cable that works

great work!

Fantastic !
