Hello all

Does anybody know if is possible to run CP/M programs in MSX1 under MSXDOSv1.x?

It should be, as MSX-DOS is backwards compatible with CP/M. I have never tried to run any CP/M software, tough.

Yes, only some more exotic disk routines may have some compatibility issues (ie CP/M set track, select disk, sector translate and read sector commands do just nothing or return error), but normal CP/M programs should run just fine with MSX-DOS. If there is possibility to select terminal emulation, you should select VT52.

The real problem is that msx1 has only 40 columns, where 90% of the old cp/m programs ask for 80 columns
Apart this, provided that the program does not use exotic disk routines, you have also to copy the cp/m files on msxdos disks (the file systems are different)

A lot of thaks, for all the replies.
I had tried Microsoft Multiplan and works fine. The only problem is 40 column display

Best regards,

You can use 80 columns on MSX2
