    From Gavin Crate@21:1/5 to All on Thu Dec 31 07:29:47 2020
    Hi comp.sys.transputer!

    Just to let you all know that I've released the Inmos T414/T425/T800 Transputer VBC emulators for the macOS on my website. See:

    https://sites.google.com/site/transputeremulator/Home/vbc-emulator

    It should be a simple task of downloading the file, unzipping it and then storing the executable file in the following location on your Mac:

    /usr/local/bin/


    Have fun!

    Gavin

    Thanks for taking this on! Do you have the source up on GitHub or
    anyplace like that?

    Gavin replied, but I don't think it made it through to the newsgroup:

    I’m glad you are making use of the macOS version of the Tx VBC
    emulator. I’m sorry to say that the source code is not available for
    public release.

    If you find any issues running the emulator on the Mac please let me
    know and I’ll attempt to fix them.

    That's unfortunate, why can't you share the code? It looked like it was
    based on previous open source effort, which is why I was hoping it would
    be available.

    I'm not using your binary releases because I prefer to build things like
    this myself, and to run them on my NetBSD and Linux systems. I don't
    think there's much to be gained from keeping emulators closed for stuff discontinued 25+ years ago. (Though I do quite understand other
    circumstances, I have changes to projects I can't release without
    permission from my employer...)

    Hello Chris et. all,

    There are two versions of transputer emulator available on my website. The first is the jserver emulator which is a highly modified version of Julian Highfield's original T414 transputer emulator, supporting T414, T425 and T800 processors and multi-
    processor support. The second is the T414 / T425 / T800 VBC emulator which is re-written from the ground up by my very own hands, using the ucode code I extracted from the REAL transputers.

    The source code for these two projects are not available for public release, only the execute code. These emulators (in particular the jserver) have been available for many years to the transputer community for free use.

    If you want source code then Andras Pahia has a working version of Julian Highfield's original code supporting both T4 and T8 emulation. See https://github.com/pahihu/t4


    Regards

    Gavin
