I remember this being discussed a while back, but didn't pay enough attention at the time. The DOS-73 card for the Unix-PC/3B1 has 512K of RAM on it. However, some of that RAM is used by "DOS-73" itself (presumably for the hardware emulation and communication with UNIX), so the board does not look like a full 512K MS-DOS machine to DOS software. Specifically "chdsk" only sees 483K of total memory with 425K available. I suppose on a real 512K MS-DOS machine it would say 512K total memory. Well some MS-DOS software is written so that if it expects to run on a machine with at least 512K of ram, it just won't run if it thinks there is less. I'm in the position right now of fighting one of those programs. Does anyone know of any way to squeeze a little more memory onto the board, or otherwise get around the problem? -- Ken Mandelberg | {decvax,sun!sunatl,gatech}!emory!km UUCP Emory University | km@emory BITNET Dept of Math and CS | km@emory.ARPA ARPA,CSNET Atlanta, GA 30322 | Phone: (404) 727-7963
