    Hi Transputer fans!

    For those of you who have not been following my "what happening" page on my website, I've spent the last couple of years extracting the ucode (or VBC) from the Inmos T414 Transputer and writing a fully working Inmos Transputer T414 Rev. B VBC emulator.
    It has been quite a challenge to say the least.

    The emulator executes using the ACTUAL microcode which I extracted from the REAL T414 Rev.B Transputer. I've written all the code (approx. 10,000 line of C) to emulate the data paths, the registers, alu, conditional logic, the Byte move logic, the micro
    controller, the memory access controller (interfacing to 4Mbytes of memory), the timers and the 4-off channel interfaces. It also integrates the Inmos ISERVER functionality for keyboard, screen and hard disk support.

    For those of you interested and who want to have a play, please check out my website page for more details:

    I would be very keen for extra help in running Occam test cases (written and compiled using the Occam toolset D7205a) to test the emulator and help locate and resolve the last remaining bugs.


    Have fun!

    Hi Transputer fans!

    I just wanted to post a quick update to say that I have now finished working on the Inmos Transputer T414 Rev. B VBC emulator. It has been quite a challenge to say the least but at last the MINIX OS runs (well just about!) on the latest release (version
    2.1) and so my work is done. Well, that was the original reason I started the project to extract theT414 VBC microcode back in 2015.

    For those of you interested and who want to have a play, please check out my website page for more details:

    I hope to publish some papers over the next few years with my finding and share the inner workings of the T414B Transputer.


    Bye for now

    P.S. Just for fun the BBC has just released archives for a computing TV show aired during the 1980’s. Check the link for some Transputer gems:
