Ok what’s this. A card underneath the drive bay on the motherboard. I’m not sure how to get to it yet so enjoy these keyhole pictures.
Lots of GALs? Hypertec? An accelerator? Maybe that’s the 486?
Found the part number FRU 92F0437 on the board which is a IBM PS/2 486DX33 Processor Upgrade Card. Pretty cool!
I’ve never powered it on so let’s open it up and see inside.
Clean and tidy! Pretty sure that’s a SCSI card on the far left going to two HDs and a CD-ROM. Next to it looks to be a RAM card with 12MB in 3 SIMMs. Next to it an IO card of some kind. Also two “IBM FRU” cards (more RAM?). This thing feels tricked out for the time!

Curiously, this IBM PS/2 8580 is a 386 machine but it has a badge on the front that says 486?🤔

Getting things sorted for the VCF swap meet this Saturday in NJ. Pulled this IBM chonk from the basement. 20.5 kg of IBM iron. Good thing there’s a handle on top 😄
