and i got a type 2 planar for an IBM PS/2 Model 80. this one is meant to run a 386 at 20MHz. i could use it to upgrade my model 80 which has the slower type 1, 16MHz planar.

(there's a whole story about the type 1 needing matched memory cycles and the type 2 not needing that)

@tubetime Weird place for the 7. Does it come from a keyboard with the numpad on the alphabetical keys?

@tubetime oww. Never seen a crack in a chip like this.

@tubetime so that's what it is! A friend of mine gave me a motherboard very similar, noting that there was almost no estàndard conector. I knew it was an IBM but never looked into it further than that.
