I got a Pentium 90 CPU (gold cap, FDIV bug) for my intel Plato, BUT it has a broken pin. Its the middle, Pin of the key edge, direct in line with the pointer from the CPU cover.
The Pentium data sheet says it the pin provides the signal DP5 for data parity. I found no option in BIOS setup for parity usage and i have no RAM with parity.
The CPU seems to run fine (Winstone 95) in the Plato with my periphery.

Are there applications which make use of the DP0-7 ?
