Thread: Interdata Model 1 Information....

  1. #1

    Default Interdata Model 1 Information....

    I am looking for the service manual for any of the early Interdata systems. I have an Interdata Model 1 that I would like to restore. It uses 10-inch boards that were common in other early Interdata systems, like the Model 3. I have a user's manual for the Model 1 which has the instruction set and interface information, but no schematics. I would also be interested in any parts.
    Thanks

    a confusing aspect of the Model 1 is it is more similar to the Model 70 than the Models 2,3 or 4
    and was released after them in 1970

    you might look at the documentation on http://bitsavers.org/pdf/interdata/16bit

    I have little information on the model 1, so scans of what you have and pictures of the boards would be useful

    given that it has a model 70 style front panel, I'm guessing it is a microcoded machine with semiconductor rom microcode store

    I have photos of all the Model 1 boards on my website at http://www.archerservices.com/History/Interdata.htm
    bottom half of the page. The top half of the page is about my PE 1610 (Interdata 8/16).
    The model 1 isn't microcoded. The processor consists of three boards with all logic built out with simple TTL and DTL chips.
    I think it's closer design to the model 3 & 4, which also used the same style 10-inch boards and back plane.
    I scanned my Model 1 user manual and it was recently uploaded to BitSavers. It has lots of good information, but no schematics.
