I’ve come into an HP-Apollo 9000/425t which uses memory boards with 72-pin headers rather than using SIMMs.
Based on what I can see in pictures online, the boards themselves don’t appear to be anything special (they just carry TMS444000 etc. DRAM) and the connections aren’t anything special either, so I figure it shouldn’t be hard to design a SIMM adapter.
Does anyone have or know where I could find the pinout and timings?
