The AT&T > card is the same as the card manufactured by AST for the PC6300. Not quite, if you're talking about the Enhanced Expanded Memory board. (This EEMS board is very much like an EMS 4.0 board, as I explained in an earlier posting [which I didn't keep a copy of, so don't ask].) The board was designed to work slightly differently in an AT&T PC 6300 and an AT&T PC 6300 PLUS. The software "looks at the computer's navel" to decide which it is, and a 6300 with a V30 "looks" like a 286 to the software. There was a patch that corrected this. Sorry, I haven't the faintest idea where to get it from. Can anyone pick it up from here? Paul S. R.
