If you remember, I was having trouble installing ZSDOS on a Xerox 820-II.  One
of the problems was in using MOVCPM to create an absolute file os the system.
I kept getting a SYNCRONIZATION ERROR.

Jay Sage explained that this was probably because the system was not created
using that version of MOVCPM.  I had trouble believing this, because I only
HAVE one system disk, and unless it was screwed up, which did not seem to be
the case, then MOVCPM and the system HAD to be the same.

Well Jay was right, but not in the way he had ment.  In playing around with it
some more, it seems ZSDOS's INSTALOS modifies MOVCPM or something like that.
Using the original master system disk, I formatted a new disk, sysgened it, and
then copied MOVCPM and the other files needed to install ZSDOS.  I then booted
the system using the new disk, and ran MOVCPM.  It worked fine, but I didn't do
anything else with it.  I then ran ZSDOS's INSTALOS in the normal way.  Note
that it uses MOVCPM.  As before, I got the "bit relocatable table not found"
error, so I decided to create an absolute file of the system.  MOVCPM gave me a
SYNCRONIZATION ERROR.  I deleted MOVCPM and then copied it over from the master
disk again.  It ran without a problem.

I tried this a couple more times, just to be sure.  If I ran INSTALOS in the
normal fashon, then I was NOT able to use MOVCPM anymore, until I deleted it,
and copied over a new version.

Strange!
