SAGE CP/M 68k on SIMH

Somehow, I missed this as a ‘beta’ driver for the last public release of SIMH.

68k CP/M 1.2

68k CP/M 1.2

What makes the 68000 version of CP/M different from the i8080 version is that it was coded in C.  And of course 68k CP/M suffered the same problem every other processor incompatible ‘same os’ OS has ever suffered which is no applications.  But that is when I remembered the COM, which started out it’s life as an 8080 emulator for the 68000.  With a LOT of creative googlling, I managed to find the source, mysteriously labelled 8088M.ZIP.  I also found a binary here. But unfortunately that is as far as I got.  I haven’t managed to figure out a way to inject files into the SAGE CP/M IMD disk images.

So this is where I’m stuck, and this is my call for help.  If anyone knows how to get files in/out of these IMD files give me a shout.  For anyone interested in 68k CP/M this is your chance to get it running.

The one funny thing I found in a hex editor of the disk image was this:

Oh well.

 

***EDIT***

Never mind, me and a friend of mine (hi Lorenzo!) got the disk image thing figured out!

What is there to tell? I've loved UNIX like things since I was first exposed to QNX in highschool (we had the Unisys ICONS!), and spent the better time of my teenage years trying to get my own UNIX... I should have bought Coherent in retrospect.. Anyways latched onto Linux in 1992, and then got some old BSD admin books and have been hooked on the VAX BSD & other big/ancient things since...!

    • I should have guessed…

      $ wine imgtool.exe identify CPM68K12.IMD

      wine: Unhandled page fault on read access to 0x00000000 at address 0x0 (thread 0026), starting debugger...

      let me boot into windows…

    • imgtool & winmgtool are no longer distributed for some reason. the imgtool.exe I found crashes too under windows 7. Oh well, thanks anyways.
