To clarify: He's making an adapter for plugging 72-pin SIMMs into a 64-pin
socket.

Hmm, I've got a 486 Bravo, but it uses 72-pinners. Still, it's a queer
machine. So far, no non-MS OS has worked on it.

How's the pinout?

Bastards.

Don't get me started on PS/2s. I collect them, but they are nightmares to get
going. The actual reason I started collecting them was that I found one in a
dumpster and found nout that not a single part could be reused in another
machine.
