The more insane thing to have done would be to look at the 68k version of CP/M (written in C) and getting it to run on the 386 in protected mode……………….

Insane!

https://uploadfiles.io/gwfr692t

you cant get a more complete collection anywhere else
better hurry and grab it before its gone again.

The vetus ware link is just in case.

Although its an older & less complete release, there is more than enough to biuld your system from the ground up as you see fit.

“This is the original BOOT ROM distributed with CP/M for the SBC 86/12 and 204 Controller. The listing is truncated on the right, but can be reproduced by assembling ROM.A86 from the distribution disk.”

and

“This program resides in two 2716 EPROM’s (2K each) at location 0FF000H on the SBC 86/12 CPU board. ROM 0 contains the even memory locations, and ROM 1 contains the odd addresses.”

This comes from a file called ROM.A86 in a source code archive called c8611src.zip.

Is this the equivilant of the ROM BIOS in a regular PC? If so, then there might be a path of understanding in this, since it’s the actual source code.

Ages ago I thought that taking CP/M for the 68000 would be a better choice as it’s written in C. Although I didn’t get far enough…

And there was that VAX port..

Anyone here familiar with CP/M-86 1.1 source code? I’m looking to “modernize” CP/M-86 1.1 by (initially) just fixing up CPM.SYS (I have the three necessary files: BIOS/CBIOS.A86, CCP.A86, and BDOS.A86) a bit. Rather than using the “patches” (AT and Y2K) on the binaries, why not fix the problem in the source code, so the patches aren’t necessary?

Try exchange… Its decapitated CP/M and can manipulate various disk images..

Late to the party by a whopping 7 years. I have a copy of CP/M-86 1.1 (.IMG disk image) on an emulator called PCEm. It’s running in XT (8088) mode, based on the BIOS I’m using. I’d like to tinker with some CP/M-86 source code files, but they’re in Windows/MacOS X. Not sure how to get them into a 160K floppy image. I can create a 160K disk image in PCEm or an image program in Windows, but other than the fact it shows the same screen of dots (when I dir from the B drive), it never shows any files I’ve injected. I can’t read disk images I create from PCEm in the Windows image program (says it’s corrupted or something), yet disk images I create in the image program show nothing when I try to dir them from the B drive in PCEm. Weird.

Hi, this is a very late feedback, but it’s really “up to date”.
Plz feel free to visit my blog (again) and look how beautiful CP/M-86 runs in VMWare, VirtualBox and even on a Thinkpad T23 – slightly more modern than a PC/XT.

Good news and bad news. I actually found some of my old magazines, but it looks like I pared down the collection so the issues I NOW want, are gone. I found 5 ProFiles issues (8/86, 5/87, 8/87, 8/88) and 3 Micro Cornucopia (37 - 39). Amazed I found any really (I think my collection use to go back to 84 or so).

Thanks for the tip on multicore. If I have any problems, I'll give it a try. So far everything is working.
