ZCPR is a replacement for the rather anemic CCP (console command processor) and a few additional utilities. Of ten the BDOS and BIOS are unchanged and that is the core of CP/M. The CCP is user interface. The DOS analog of that would be Windows3.1 is not DOS. See the point! Now ZRDOS or ZSDOS is a totally different codebase and non DRI product that is CP/M compatable and draws form the ZCPRx lineage. Allison

ZCPR & Other CP/M Extensions (Was: RE: CP/M 1.3 memory requiremen t)

ZCPRx is CP/M! I spent a log of time customizing ZCPR 2.2, but never got around to moving to ZCPR3. Can anyone give a thumbnail sketch of the differences, keeping in mind that I'm fairly familiar with the 2.2 version? In addition to tweaking & adding stuff to ZCPR2.2, I also adapted someone else's take on implementing resident system extensions (RSXs) under CP/M 2.2/ZCPR, as well as putting together a small library of RSXs that would work with it (as well as CP/M 3). Any interest in that stuff? I think the floppies may still be readable... -dq

system/36 awefully quiet...

Jeff, It sounds to me like you don't want to live very long. Big power hungery computers and old inadaquete wiring just don't work well together.

CP/M 1.3 memory requirement

NS* DOS is a good place to start. Once you have the IO right for that then doing it for CP/M will be fairly easy. Allison

MULTICS Installation, Halifax

In fact, a DPS-8 can't run Multics, only the DPS-8/M can (in addition to the 6180 and GE 645). However, Multics could be re-implemented on any architecture that either provides a paged, segmented virtual memory with rings of protection, or, on any architecture fast enough that those features could be emulated. regards, -dq

Hello from a new member

by jjackson＠salsa-digital.com

Hello, I found this group while looking for information on an archaic computer system. I have several systems at home that may qualify as 'classic' computers... a Heathkit 6500 computer trainer (I think) with documentation SWTPC 6800 - in storage with a hefty 4k RAM Amiga 1000 Amiga 4000 ...and a few others. I am going home tonight to look at them and see if I might have something of interest for someone else. Intel (360?) Multi-Bus I system used for development... complete with software and manuals. I also have much documentation. I'm a packrat when it comes to User's Manuals. But it is now time to clean out the storage room. <sigh> I have information for those of you with Amiga 4000's for repairing your A3640 CPU boards. This is on my web site. Also - for replacing the capacitors in the Audio section. (This applies to any of the Amiga series. They used polarized caps in a uni-polar output stage of an op-amp.)

CP/M 1.3 memory requirement

I'd say 1.4 was the first commercially viable version but, 1.3 was the first complete working one. Allison
