PPorkyPiggy replied to the thread CP/M 2.2 Distribution + MDS-800 Emulation.I have reconstructed the 1.4 distribution disks! Now we finally have a generic MDS-800 version of CP/M 1.4 and build tools for MOVCPM to...

PPorkyPiggy replied to the thread CP/M 2.2 Distribution + MDS-800 Emulation.I knew that of course, that's why I tried to get it to boot under emulation in the first place. I wasn't surprised by the fact that it's...

PHello, I have spent the past few days cleaning up two generic CP/M 2.2 disks from Digital Research (DRI). CP/M had generic versions...

PPorkyPiggy replied to the thread 86-DOS 0.11 Source Code Reconstruction.Big Update This is a very significant update; essentially, the disassembly is 100% complete, and there's only some labelling and...

PPorkyPiggy replied to the thread Zenith Z-100 can read early 8" 86-DOS disks.What if you change the stack buffer from 256 bytes (DW 128 DUP(?)) to 512 bytes? It works in the emulator if I do that. Sincerely, Pig

PPorkyPiggy replied to the thread Zenith Z-100 can read early 8" 86-DOS disks.Would certainly kill performance if you enable all of them (I did that for the IBM PC ports, to work on modern computers). Size growth...

PPorkyPiggy replied to the thread Zenith Z-100 can read early 8" 86-DOS disks.The lockups! That's the stack overflow I mentioned earlier. Compare my v1 and v2 sources and apply the stack switching code to your BIOS...
-
PPorkyPiggy replied to the thread Zenith Z-100 can read early 8" 86-DOS disks.Of course, because it's really just a hack and 86-DOS is not 100% compatible with MS-DOS 1.20 and later. However, with this 86-DOS 1.14...

PPorkyPiggy replied to the thread Zenith Z-100 can read early 8" 86-DOS disks.Put them on a 320K Z-DOS 1.25 disk and change the first byte of both FATs (logical sectors 1 and 2) from 0xFF to 0xFE. Sincerely, Pig

PPorkyPiggy replied to the thread Zenith Z-100 can read early 8" 86-DOS disks.Alright, I couldn't get the 160K version to work (under the emulator), so I made this 320K version. It boots, that's about all I can...

PPorkyPiggy replied to the thread 86-DOS 0.11 Source Code Reconstruction.The source code is now up on my GitHub, with full change history: https://github.com/Piggy63/86-DOS-0.11. If you have anything to...

PPorkyPiggy replied to the thread Earliest known copies of 86-DOS....The OEM modules of all 86-DOS versions for the IBM PC are now up on GitHub: https://github.com/Piggy63/86-DOS_PCAdaptation. If you want...
-
PPorkyPiggy replied to the thread Zenith Z-100 can read early 8" 86-DOS disks.It might just be a stack overflow... or it could be something else. You'll have to debug it, unfortunately. Because I don't have a Z-100...

PPorkyPiggy replied to the thread Zenith Z-100 can read early 8" 86-DOS disks.The BIOS for 86-DOS 0.x is not ready yet, but I think I've hacked the Z-100 MS-DOS 1.25 BIOS enough to be compatible with 86-DOS 1.14...
