Subject: 22DISK: MS/DOS <=> CP/M File transfers.

Does anyone use the 22DISK shareware program on a PC, to transfer files to
and from Xerox 820 series disks?  At this point, I only have the shareware
verison, not the registered version.  I thought I would make sure it would
work for me, before I actually paid the registration fee.  I can *NOT* get
it to work however.

The shareware version supports 5 different Xerox formats, though one has
nothing to do with the 820's (perhaps it's for the Xerox 6085 workstation).
I started out trying the standard Xerox 820-II format.  It could find no
files on the 820 disk I was using, even though my 820-II said there were.
I tried formatting an 820-II disk on the PC, but the 820 could not read it.
I assume this is because my PC could not write track 0 as single density.

The other day, I recieved some disks through the mail, contaning some
public domain software that I had been looking for.  It had been formatted
for the 820-II 16/8 DEM.  22DISK could not read these disks either, even
though two different DEM formats (called EM-II in Uniform and 22 DISK),
including the proper one are supported.

The only Xerox 820 series format I have not tried is the single density 820
format.  In addition, when I looked at the Disk Definition file for 22DISK,
I think the section for the single density 820 is wrong.

What I would like to know before I waste any more time on 22DISK, is if
anyone else has used it with any success on one of the Xerox 820 series
computers.
