Mike Sprague described his travails with getting ZSDOS installed on his Xerox computer. >> So, I tried MOVCPM * *.

That shows that the system you were running at the time was not one created by that version of MOVCPM, which checks the DOS serial number in the first six bytes of code. Digital Research punishes one for trying to use a 'borrowed' MOVCPM by locking up the system. >> MOVECPM ... seemed to work this time, though it came up with the >> following. >> >> CCP 0000H >> BDOS 0800H >> BIOS 1600H This may or may not be a problem. I don't remember what those values are supposed to be. I'd recommend that you look at that image file and see where the CCP, DOS, and BIOS appear. Normal SYSGEN images have them at 980H, 1180H, and 1F80H, respectively. I would also suggest that you make up a new boot disk based on the system generated by MOVCPM and make sure it works. Then go back to the ZSDOS installation. Chris McEwen at Z-Node #32 runs this stuff, I'm quite sure, on Xerox 16/8 computers. If it will work there, it should work on your simpler machine. Also, I seem to recall that the clock module menu includes something for the Xerox 820 (though I may be mistaken). Good luck. --- Jay Sage

To be fair, most MOVCPM`s incorporate at least minimal BIOS type code to boot the system, so for a general user to use a different version of MOVCPM than the one intended for the system would be pointless and confusing to diagnose. Obviously this doesn't apply to hackers, who find their own workarounds.

Thanks again Jay, and others, for the info. If my MOVCPM and operating system do not match, then I am afraid they will NEVER match. However, I still think it might have had something to do with CONFIGUR. I kept getting the synchronization error until I formatted a floppy with the master, sysgened it BUT did not configure it. Formatting, sysgening and configuring it, even using the master, resulted in a synchronization error. Anyone know the patch for defeating the serial number check for MOVCPM? I may need it here. >> Chuckle it's the same machine, not a simpler one.

Unless you start using the 16/8 board, with concurrent CP/M-80 and CP/M-86, there is NO difference between running CP/M on a 16/8 or the 820-II. Even so, I suspect the changes for ZSDOS might be no different for CP/M-80, than for CP/M, assuming it could even be installed. CP/M-80 is NOT sysgened onto the boot tracks of the bootable floppy (nor is CP/M-86). Normal CP/M is what gets installed. You have to run an application (I don't remember what it is off the top of my head) to shift from CP/M to CP/M-80. Thus, I suspect you can't even install ZSDOS on the 16/8's CP/M-80. I may not be exactly correct here, as it's been a while since I messed with a 16/8 board. It seems that there is so little software for CP/M-86, that it's really not worth my time. This does not mean, however, that I will not contact Chris McEwen. Is there a way I can contact him, besides the Z-nodes? Someday I'm gonna hook a modem to one of my computers ... someday. :-) ~ Mike (Sprague.Wbst311@Xerox.Com)
