National Semiconductor HPC16083/HPC46003 High Performance microController Family - Info Needed

    The HPC was a fine micro in its day - I believe it was one of the
    fastest microcontrollers available at the time (15 years ago?). It's a
    16-bit accumulator-based CISC cpu, with a reasonable range of addressing
    modes. We used to have an emulator for it, but it's unfortunately
    broken. It was an impressive system - a main board around 50cm by 50cm,
    with a "daughter" board at about 30cm by 50cm. The assembler was, as
    far as I can remember, free (or at least very low cost), while the C
    compiler from National Semiconductor cost extra. It's been about 10
    years since I've written a new program on the HPC, but the last
    modification I made to a HPC program was a couple of months ago.

    Talk to your National Semiconductor representatives about tools and
    documentation. If they can't give you the tools, but can authorize a
    free copy, then I can send you a zip of the assembler and linker (and C
    compiler, if they authorize that too). That might be easier to deal
    with than the originals, which I believe came on 5 1/4" floppies. The
    documentation would be harder - I think I only have it in dead tree format.

    As long as you don't have to debug anything (which you might avoid, if
    you are only modifying a working system), then the HPC is fine to work
    with in assembler, or even its (slightly limited and very old fashioned)
    C compiler. It's certainly much more programmer friendly than many
    8-bit micros.

    Good luck!

    email address.)

    I inherited an embedded computer using the National HPC 46003 processor. I
    am obliged to correct some programming problems in the code but I have
    little information and no tools. I have only found some high level spec
    sheets and app. notes. I'll probably need to hand assemble the changes but I
    need sufficient info to build the object code. Does anyone have the User's
    Manual, assemblers, etc for this processor that can help?

  3. I agree with David, a fine micro - every micro that National does
    seems to dissapear :-(
    Still have the tools and documentation - Even have some spare micros
    somewhere Im sure..

    Hi dear David
    I can't find any assembler or compiler for HPC series controller.

    please help me!
