Subject: ZSDOS on Xerox 820-II

Thanks again Jay, and others, for the info.

If my MOVCPM and operating system do not match, then I am afraid they will
NEVER match.  However, I still think it might have had something to do with
CONFIGUR.  I kept getting the synchronization error until I formatted a floppy
with the master, sysgened it BUT did not configure it.  Formatting, sysgening
and configuring it, even using the master, resulted in a synchronization error.

Anyone know the patch for defeating the serial number check for MOVCPM?  I may
need it here.

What I meant to say is that CP/M is CP/M is CP/M.  Unless you start using the
16/8 board, with concurrent CP/M-80 and CP/M-86, there is NO difference between
running CP/M on a 16/8 or the 820-II.  Even so, I suspect the changes for ZSDOS
might be no different for CP/M-80, than for CP/M, assuming it could even be
installed.  CP/M-80 is NOT sysgened onto the boot tracks of the bootable floppy
(nor is CP/M-86).  Normal CP/M is what gets installed.  You have to run an
application (I don't remember what it is off the top of my head) to shift from
CP/M to CP/M-80.  Thus, I suspect you can't even install ZSDOS on the 16/8's
CP/M-80.

I may not be exactly correct here, as it's been a while since I messed with a
16/8 board.  It seems that there is so little software for CP/M-86, that it's
really not worth my time.

This does not mean, however, that I will not contact Chris McEwen.  Is there a
way I can contact him, besides the Z-nodes?  Someday I'm gonna hook a modem to
one of my computers ... someday.  :-)
