Subject: Vector 3 CP/M 2.22h CCP patching

I have been working for some time on installing a RBBS based RCP/M
system on a Vector 3 system.  I have installed XMODEM and BYE and RBBS
and am just about ready to bring the whole thing up.  I am having
one last annoying problem though.  I usually install ZCPR on the
systems I use as RCP/Ms, to allow searching back to A0> mostly.  This
makes use of the system much more straightforward.   I don't like 
DUPUSR and this allows me to keep just one copy of the system 
software online in A0: and have it accessed from any drive or user#.
We have succesfully installed ZCPR in several other systems and have
never had a problem like this.  If anyone out there knows anything
that might help, please send me mail.  Here's the problem:  We install
ZCPR and SYSGEN a disk with it.  We cold boot and everything works
fine.  All the ZCPR commands work and the prompt has changed from A:
to A0: as it should.  The system searches back to A0: as advertised.
BUT, on the first cold boot (after a ^C or program exit) the system
tries to reload the CCP and crashes with a message that looks like
this:

-SYSTEM ERROR

As an alternative we got a patch that just implements the search back
to A0: instead of the full ZCPR and tried to install it.  We got the
exact same behavior from this patch.

Any Ideas?  What is so magic about the Vector CCP?  I have called
Vector several dozen times and they have proved to be much less than
useful. I am stumped and turn to you, the DARPA CP/M wizards to give
me a helping hand.
