Comment by Paul Collins (pi314aussie[at]
I got a "turbo card" for IBM PC and IBM PC/XT. It was a self contained unit, that plugged into the 8-bit ISA slot, and a ribbon cable that plugged into the 8088 slot.
This turbo card had an 80386 and 80387 and 1MegByte RAM (in DIL 4 bank old fashion setup). The whole thing ran the ORIGINAL 16 MHz Intel chips. Boy do they run 'hot'. I thought it might have been the early versions, so I replaced those mark 1's with (then) current 386-33 and 387-33 chips. Alas, they ran just as hot as before! N.B. the 4 banks of RAM only yeilded 640k of available memory to the system. (No 384k reserved for print-spoolers or RAM-disks, like the early "AST six-pack").
