Unknown onboard IBM chip.


Inmos IMSG171P-35 is 35MHz Ramdac designed to be compactible with IBM PS/2 VGA graphics systems. Datasheet is here. So i guess it can be part of IBM PS/2 motherboard with 1st vga chipset or XGA 1. Questions are: is it silver chip really graphics core or it ended with rest of motherboard in recycled stuff? (got it as you see it), chipset name, source computer name, memory size/type, year.

Vlask's chip:
