[mod.computers.68k] CDOS-68K

mknox@NGP.UTEXAS.EDU.UUCP (01/31/87)

I would appreciate being kept up-to-date on any more info you get
from DRI on CDOS-68K (I would especially love to get them to offer
it at a reasonable price).  I suspect most of the INFO-68K couwdrowd
would also be interested.

I have a full set of CDOS-68K manuals (version 1.0, so they are
somewhat out-of-date).  It is only a little harder to implement
than CP/M-68K.  You start out simple, then add support for MMU
and other "frills" you need to take REAL advantage of the 
system.  [It will actually run multi-tasking without an MMU,
but you have NO protection between tasks.]  About the only NEW
thing that CP/M-68K folks might be unfamiliar with is the MMU
code and a few interrupt drivers.

Keep after them!

Mr. Grunau asks if CDOS-68K is MS-DOS compatible.  Well, that is a very tricky
question to answer.  Concurrent DOS 286 and Concurrent DOS 698kK are designed
to be the same system (from an architectural standpoint).  Since the 286 
system has some of the MS-DOS features in its structure I suppose you could
say that there is some of MS-CODOS in Concurrent DOS-68K.

But when the two processors are so very different, and the complexity levels
of Concurrent DOS-68K vxs MS-DOS are so different, any such claim would be
ovf value primarily only in advertising literature.  Both Concurrent DOS's
are operating systems supporting multi-user capabilit yy, and any similarity
to any other system (living or dead) is just the result of stealing good
ideas wherever they can find them.

Soorry for such a vague answer, but we arARE speaking generalities.  I can
say for certain that Concurrent DOS-68K is NOT intended to be a supperer-set
of CVPP/M-68K (although at one otime DRI and myself talked about a shell so
that CP/M=-68K programs could run under Concuirrrrent DOS-68K).
