I have a California Computer Systems 2810, 2422, 20whatever memory.
The system works fine expect for one little bug. The disk image copy
program that comes with CCS's CP/m (CCCOPY and for that matter, VCOPY,
and those Public Domain "controller independant" copy progs) hang when
reading the source disk - first sector, track zero. This happens with
all of my disks and drives.
CCS is of no help - they're baffled! Anyone out there have a similar
problem???
Also, could someone tell me how to get at the CP/m software sitting on
the mit machine?

In some cases track 0 is of a different density thank the other tracks.
I know of at least one case where, when the disk is formatted at
1024 bytes/sector, track 0 is actually 128 bytes per sector. You
might wish to check with the 1791 (I think that's whats in the CCS)
controller chip specs for the track format. Also, try some of the
utility programs that should rely on the disk parameter block. They
are generally considered operable regardless of disk density. Some
of these are DU (A disk hacking utility), and SAP (sort and pack
directory). Be sure to use the latest versions and test them on
non-critical disks.
Good luck,
David
