I am looking for the documentation of an old Intel motherboard with the following numbers: PBA 620028-202 or AA 634662-203 or Kalex 94V-0 K658.
Can you give me a link?
I am unable to find your AA number. Can you verify the AA number, or provide a photo of the label and labels around the AA number?
Well, you got me on this one. 4 ISA and 3 PCI slots puts it in the ancient category. There is one other guy here that might recognize this relic.
OMG! That looks like the Ninja board. This was one of the first PC mobos (if not THE first) that I was involved with at Intel (ca Q4'1993/Q1'1994, though ancillary, since I was still doing iRMX III work then). If I remember correctly, the name for this board was the Intel Classic/PCI Expandable Desktop or something like that. That's Socket 3, so 486SX, 486SX2, 486DX, 486DX2, 486DX4 or Pentium Overdrive processors. The board had the Aries (420EX) chipset (S82425EX, S82426EX components), discrete SRAM L2 cache and SIM memory.
As for documentation, I was unable to find any on the Intel site. There are a few breadcrumbs that I hit in an Internet search, but not that got me to an actual document. I will check with some of the Intel folks tomorrow and see if they have any ideas...
