So, on a lark last week I bought a fairly late (circa 1991) HT12A based mobo on ebay hoping that there wasn't any battery leakage (pics didn't show that area all that well), and I guess I got lucky, the board looks damn near mint condition. It'll be getting a Harris 286-25 in the near future as well as a crystal swap (bought some sockets for that) as well as a 20 mhz 287 if I ever see one come up. That brings up the question of memory: It came with 80ns 3-chip parity SIMMs. So my question is this: Just what 30 pin simms are compatible with a 286 mobo? I'll assume I need parity for now and the documentation I've found implies 4mb is the max. Is FPM compatible with 286s? Oh and pics will be coming!
