    Best "starter" CP/M machine? (and looking for KAMAS outliner software)

    Same here. I based my system on CP/mega88 by Takashi Toyoshima, (also an i8080 emulator) but turned it into an Z80 emulator with several more modifications. It is now running in an ATMega 168 @ 20 MHz. it boots CP/M 2.2, CP/M 3.1, Dos+, ZCPR2/ZSDOS and ZPM. The apparent speed is something like...

    Boot from MFM disk drive - How to install DOS?

    Maybe you could benefit from using hTest-hFormat from Kolod research. I have version 2.1 (attached) It comes with an extensive manual, of which I do not have a digital copy. Maybe you can find it somewhere on the web.

    Good DOS terminal emulators for the 5150 that run on a 360KB floppy?

    Ah, OOPS... Correct image attached. Consider PC-File as a bonus :-P

    Good DOS terminal emulators for the 5150 that run on a 360KB floppy?

    My suggestions would be PC-Talk , Bitcomv3.02 or Supercom v1.01. And then there is Smartterm v 2.4, but that one comes on 3 floppies. (installs on only one though) Images are attached. If you need only the files, let me know

    Really cheap CP/M

    Using download only needs 2 steps: 'hexxfer filename' to create the package, and ALT-S to start serial transfer, (Minicom already knows where to find the package file) select ASCII and ENTER. It ends up under the correct user too. I never bothered to adapt hexxfer for more than one file. If I...

    Really cheap CP/M

    I use a version of Grant Searle's (http://www.searle.wales/) DOWNLOAD.COM for uploading files using the console interface. I have modified versions that work on most CP/M derivatives as well as a packager program in BASH. It is very useful, it only requires a stable serial connection and robust...

    CP/M 2.2 BDOS serial number clobbered

    I understand why you would consider serial numbers. Microsoft does this all the time. I have difficulty understanding why you would want to forcefully match BDOS and CCP when you were supposed to treat them as monolithic anyway. I Guess the possibility of overwriting (part of) BDOS became...

    CP/M 2.2 BDOS serial number clobbered

    I checked, My Ampro littleboard BIOS also loads both CCP and BDOS at warm boot. This seems to be the best practice then. Thanks for the help

    CP/M 2.2 BDOS serial number clobbered

    Then Why use a serial (version) number at all? I can understand you don't want to load a CCP which does not match the BDOS, but when you always load both there is no point to it is there?

    CP/M 2.2 BDOS serial number clobbered

    I noticed that my CP/M 2.2 implementation would sometimes crash after completion of certain programs. Examples are Turbo pascal, toolworks C/80, Digital Link v1.31. I have determined that this is caused by said applications overwriting the first 6 bytes of BDOS, which contains the serial number...

    Really cheap CP/M

    The words 'sense, sensible, useful, cost-effective' etc have absolutely no meaning with this kind of thing. Talking of sensible, I managed to free up another IO pin so now i have a drive LED too. The sensible thing would probably be to double the RAM or something, but, come on we're talking...
