If the Xerox 6064 PC is the same as the ATT 6300 and NOT the 6300+, then you can only put 64k chips in the second bank of memory to get the 640k maximum. The 6300+ uses a 80286 and can handle up to 7meg of memory, but I think MS-DOS still only recognizes 640k. --Mark Guzzi University of Illinois at Urbana-Champaign ARPA: guzzi@uicsrd.csrd.uiuc.edu guzzi%uicsrd@uiuc.arpa CSNET: guzzi%uicsrd@uiuc guzzi%uicsrd.csrd.uiuc.edu@csnet-relay UUCP: {ihnp4,convex,pur-ee}!uiucdcs!guzzi USENET: ...!{pur-ee,ihnp4}!uiucdcs!guzzi BITNET: guzzi%uicsrd.csrd.uiuc.edu@WISCVM.BITN

The reason for the published 7meg restriction has to do with how many memory expansion cards will fit in the three 16-bit bus slots. With 256k memory chips and one meg on the motherboard and 2meg each on three exp. boards yields 7meg. However, AT&T makes 1megabit chips and at some point in the future you will be able to have a 16meg PLUS. -- +--------------+------------------------+-----------------+ | Mike Vrbanac | AT&T Bell Laboratories | Columbus, Ahiya | +--------------+------------------+-----------------------+ | Unix: {cbosgd|ihnp4}!cbuxc!gmv | CompuServ: 76054,113 | +---------------------------------+-----------------------+
