    Default MyZ80 CP/M emulator help

    Hi, I'm looking for a later copy of the MyZ80 CP/M emulator by Simeon Cran. I have an early copy which is really useful but in some of the documentation it mentions a 2.0 version. Has anyone seen it or used it?
    Best regards

    IIRC the latest version of MYZ80 is 1.24

    Thanks for the reply. I have read through the documentation again and I think it's a bit of wishful thinking on my part and a late night in front of the monitor. Here is the paragraph from the documentation.


    Registered users may request information about MYZ80 which is not
    provided with the package. Requests of this sort made by
    unregistered users will be ignored unless it is considered that
    the information would be generally of use to registered users as
    well. Registered users will also be given priority when it comes
    to sorting out any problems they might be having in adapting MYZ80
    to their needs. Registered users will receive one free upgrade
    from the version that they receive when they initially register.
    The registered user can request this whenever they feel the
    upgrade is worthwhile. This policy does not allow for major
    upgrades (e.g. version 1.xx to version 2.xx would require re-
    registration, however version 1.05 to version 1.90 is allowable as
    the free upgrade). Upgrades beyond the first free upgrade but not
    including major upgrades are available for $10.

    So the last version I have is also 1.24.

    Has anyone had a registered version of this great piece of software?

    What are you trying to do with MyZ80? I've got a JAVA program (should work without recompile anywhere a JRE is available) that emulates CP/M 3 and CP/M 2.2 that I use for running CP/M utils as simple commandlines, for example from Makefiles to automate production of CP/M images. I think there are probably lots of similar ones out.

    Thanks Larry, maybe we should just rename this forum to "Just ask Larry"😀

    Hi, I'm using it to write test Z80 assembly with CP/M. I use the ZdevStudio IDE and push the results over to the MYZ80. Mainly learning at the moment but cutting my teeth on BIOS and Monitor writing.

    OK, so you are using MyZ80 to run the results of what you compile/assemble with ZdevStudio? I take it you are not targeting any particular platform/hardware, just running generic code? Are you experiencing problems with MyZ80 or is it working as you need it to? What is your host platform (Windows, Linux, OSX,...)?

    No problems so far (touch wood) and running it on Linux under DOSbox. I suppose my intended target is the Intertec Superbrain if I ever get her working properly again. Currently I have, with help, a working monitor and also trying to put in a RAM test if I can whittle it down to fit.
    I was just wondering if there was a later version of MYZ80 than 1.24.

    Based on the wording of this paragraph, I take it that it's just an example of upgrade rights, not a statement that those specific versions exist or ever existed.

    e.g. means "for the sake of example"
