From: Seymour <JOSEPH@RU-BLUE.ARPA> 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. Seymour -------

Guys, I know from nuttin about Vector 3s and not much more about the software you're implementing... but I DO have a system looking to Default disk Same User Area (e.g., from B3 to A3) first, and then to Default disk User Area 0. Works for everything but overlays! Grabbed it from two different files, a somewhat documented explanation and source code can be found (much to my surprise and pleasure) in my article TOADBIOS.DOC now residing in all its glory at SIMTEL20 MICRO:<CPM.GENDOC>TOADBIOS.DOC.1, available via ANONYMOUS FTP. (And more glory to the original patch authors!) Hope it can be of use. Regards, and good luck. David Kirschbaum Toad Hall (ABN.ISCAMS@USC-ISID)
