Really nice!
I like the design on this one 😀

IBM stuff are always excellent, kudos on getting this!

Cheers guys, will post updates during and after cleaning. 😀

Wow those pics give me a stroke of nostalgia, I had an identical Aptiva 2144 back in '93 or so. 😀

Awesome machine for its day, built solidly and in style. It came with a sort of fast hibernation called Rapid Resume which rocked at the time.

Looks very well preserved.

Nice machine! I really like these compact cases.

Probably IBM 🤣

Also, no cache installed?

You should have some fun with that, look forward to the after pics,

I think your right, still yet to check though what brand of CPU it is.

Yep I'm afraid no there is no cache memory installed 🙁

Cleaning is nearly finished. Keyboard is taking two days alone during the evenings! Now just letting the keys air dry and finally pop them back in tomorrow and have a finished keyboard!

All cleaned, maybe the odd bit to do but it's much better now.
The base unit was a breeze to clean. Took it to work and used our air compressor to get rid of the loose dust and finished it using cyberclean putty. The monitor was easy too, that just had lose fluff inside so did'nt even take the back cover of that. Just yet again use the air compressor and used a torch to shine light through the vents afterwards and it's spotless.

The keyboard however took alot more work. That was cleaned all manually. (Warning, lots of pictures.)

Great cleanup job! Did you take care of the PSU as well? 😀

(And nice attempt to spell VOGONS with the keyboard keys 🤣 ).

Cheers! 😀 Oh yes the PSU has been cleaned. Although not opened. Did my best not to make the fan spin too much with the air gun. All the components on the board and inside the PSU look fine. 😀

an excellent restoration! enjoy!

Certainly will! 😀 Cheers!

Beatiful! Have fun! 😀

Very nice. Are you going to put OS/2 on it?

Cheers guys! 😀 Not sure if I wish to put OS/2 never thought about that. I don't own a copy of OS/2.
More hardware changes. I have added a Ethernet adapter. I have changed the memory. And added cache memory which is 128KB
That is the maximum that the Aptiva can take.

But I have pinched the 128KB cache from my PVI-486SP3 which is now cacheless! :-0

I will try to get 128KB or even 256KB/512KB cache for my PVI-486SP3. It would be a double advantage of having 128KB for the Aptiva in the first place and hopefully having the chance to upgrade the cache in the PVI-486SP3 😀

Nice, Think hardware wise that's the IBM complete?
Like the idea of now maxing out the PVI-486, got to love when things fall together like that.

Yep I think the IBM hardware upgrades are complete. It now has 2x 8MB 60ns fastpage ram and changed the HDD to a seagate 1.2GB and cloned the old drive over so I do what I wish without loosing any of the original Aptiva software. I do have a AMD DX4 100 MHz CPU however it's 3.3V and I think the Intel DX2 66 MHz is 5V. The DX4 may run fine but I think the L1 cache could get fried overtime. There is no voltage setting that I can see on the mainboard. I do have 2x AMD X5 133 CPU's that could work in my ASUS VL/I-486SVGOX4 & ASUS PVI-486SP3 but both requires BIOS flashing I'm not prepared to take that risk as flashing the BIOS on 486s can not be as straight forward so I'm leaving them the way they are and also happy with the IBM with the DX2 66. 😀

I've got 256KB cache on the way though 😀 I've chosen 32k8*8 combination.

I'm guessing that keyboard uses buckling spring switches?

Yes it has buckling spring switches. I'm using this keyboard right now on my main rig. It is the Model M2 which has the same buckling switches as the original Model M. The keyboard does not quite have the weight and build quality of the original model M but it's still a pretty nice keyboard. 😀
