>>I have to convert a system using foxpro 2.5 (?) on CDOS. Is this compatible with MS-DOS? Can I just bring a laptop down and copy his harddrive or does CDOS use some special disk format that I won't be able to read? Thanks for any help on this old subject.

>Boy Marcus this rings a really old bell. Wasn't CDOS the ancient Compaq version of PC-DOS? If so, I used to do alot of dBase stuff on it and never had a compatibility issues with the other MS DOS machines in the office. And no problems even in later years when I would drag out old diskettes just to see what the hell I was saving them for. HTH

No, CDOS was Digital Research's attempt to move to a multisession DOS-compatible operating system, with limited compatibility with DOS 2.1 or 3.0; it's derived from Concurrent CPM, which was derived from MPM86. I spent a ton of time working with it, having done implementations for the Viasyn/CompuPro S100 hardware in the early and mid 1980s (we actually got Lotus running on a slave processor board under Concurrent at one point at BCP Systems, a Viasyn OEM, and I worked with Fox Software getting a mulktiuser implementation of FoxBase+ working with CCPM and CDOS.)
