Thread: National Semiconductor SC/MP Low Cost Development System Manual Needed

  1. #1

    Default National Semiconductor SC/MP Low Cost Development System Manual Needed

    Howdy,

    It's my first post here. I've been hunting for one of these systems for a long time - it was my first computer ever and was lost to the ravages of a mom on a cleaning rampage many years ago .. I'm sure some here can sympathize!

    I found one at VCF West and snapped it up!

    Here's a link to a page showing such a system:

    https://collections.museumvictoria.com.au/items/393735

    (Note I'm in California, USA not Australia - they just have some pages about the LCDS).

    I found It seems to work! I have some documentation but I'm missing the main manual for the system - pictured here:

    https://collections.museumvictoria.com.au/items/1136671

    I contacted the museum for a possible copy of the manual but no dice so far.

    Does anyone have a manual they'd part with or make a scan of? Of course I'd be willing to pay a reasonable amount for either.

    Thanks for looking.

    Geoff

    Hi,

    Yes, I have the manual. It's a part of my SC/MP LCDS, but mine isn't working so I am currently fixing it. Originally the system came with a bunch of manuals, including the system manual, datasheets, circuit diagrams and the EPROM listings. It's not a small manual and, being old, it is fragile and the spine is breaking. It will be a while before I would be able to get it fully scanned.

    Hi Geoff,

    If you have no joy, since I live in Melbourne Australia, I will contact museum and ask can I see and photograph manual.

    Will let you know.

    regards

    Hi - thanks for replying!

    river I understand about scanning the document taking a while.
    Do you know what's wrong with your LCDS? Let me know if there is anything I can check on mine that might help you.

    David thanks for the offer of checking the museum!

    Hello river and David

    river I understand about the manual scanning being tricky!
    If there is anything I can check on my LCDS to help you with yours please let me know!
    A question about the manual - does it have the schematic for the CPU card? If so a scan of just that would be very helpful!

    David thanks for your offer! Have you been to that museum before? We have a good computer history museum here in California that I've been to a few times.

    Hi Geoff and river,

    Geoff I have just phoned the MuseumVictoria and asked for access to the documentation, and also possibly the Hardware. Currently, it is in offsite storage so I have to wait for the request to be processed though their system.

    I think it's likely you would get a copy from river quicker.

    river I suggest the simplest way is to get a hold of a digital camera or mobile(cell) Phone camera and just take some pics of the CPU drawing for now.

    Upload them to imgur.com, that free, then post the image link/s here. That's way easier than scanning for now whole manual or even the cct drws. When I do this way as temp way, I take a wide pic of full drawing and depending on camera resolution I will mentally divide drawing and take say 4 closer pics of the image giving a small bit of overlap
