Is it me, or does the standard N* CP/M BIOS not support IOBYTE
redirection? I'm in the process of disassembling CPMGEN, and
therefore the system image in it. Anyways, it seems that the
low-level routines doesn't give a rat's fuzzy behind about the
IOBYTE. So, I guess I'll rework it.

Actually, I'd like a full listing of the BIOS and BDOS
source. And I inherited the system with no distribution disks
and very little documentation. Such is life; I'll make do.
In fact, I'm a little unsure of the pedigree of my copy of
CP/M. I understand that both N* and Lifeboat Associates offered
versions of CP/M. Everything on the surface indicates that my
CP/M is from N*, but a great deal of the internals if it that
I've seen so far looks like the Lifeboat CP/M stuff I've seen.
For instance, the user area looks the same, except in a different
location if the SYSGEN image (Actually, the SYSGEN image resides
at a different address at SYSGEN load time, I think.)
Ah, the mysteries of it all.
Thanks for your help and interest!!

Thanx for the guidance on PD2:<CPM.NSTAR>. I've found
a file there called NSUSER5Z.AQM which, when unsqueezed,
appears to be a N* Bios USER area which supports some pretty
sophisticated IOBYTE redirection. Good catch, eh?
It looks to be what I'm looking for, when
I install it.

You are correct. The N* bios does not support the IOBYTE. I've tried every variation of your address I can think of in many vain attempts to reach you, but all mail bounces. Several other N* people on the net with whom I'm in contact have also been unable to get mail to you. Can you supply a path from some major site? There is a lot of N* information/support available if we can talk to you. -- Dave Goodman dgee@cup.portal.com ...sun!portal!cup.portal.com
