Subject: Trouble Installing ZSDOS on a Xerox 820-II

Has anyone ever installed ZSDOS (by Plu*Perfect) on a Xerox 820-II?  Can it be
done?  I have had one heck of a time trying!!!  Bridger gave me the phone
number for one of the authors, but before I go bothering anyone at their home,
I thought I would first check here.

When I tried using INSTALOS in the normal way.  I got an error message saying
"Bit relocatable table not found" (or something like that).  The error, when
checked in the manual, said that something was probably non-standard, and
suggested trying MOVCPM to create a file, and use INSTALOS with the /A option.

So, I tried MOVCPM * *.  I kept getting the message SYNCRONIZATION ERROR, and
the computer locked up, forcing me to push the reset button.  I finally
reformatted the disk I was trying to put ZSDOS on, and SYSGEN'ed it from my
Master System Disk.  I did NOT run CONFIGUR like I normally would.  Once the
needed CP/M and ZSDOS files were copied over, I ran MOVCPM * * again.

This time, MOVECPM worked.  It would have defaulted to a filename of CPM60.SYS,
but I named it SYSTEM.MDL so I could use the default in INSTALOS.  At that
point, I ran INSTALOS /A, and used SYSTEM.MDL.  It seemed to work this time,
though it came up with the following.

       CCP   0000H
       BDOS  0800H
       BIOS  1600H

Not exactly what I was expecting for a 60K system!!!  Not being happy with
this, I continued on anyway, and replaced the DOS using ZSSYS.ZRL.  I then
SYSGENED the disk using the resulting MDL file.  As expected, the computer
locked up when I tried to boot it.

I really don't know what to do next.  Any suggestions?
