      Hi Lee,

      Are you able to image those disks?

      Wow; what an impressive piece of equipment! Looks like an 80x24 video
      display, twin 8" floppies, BASIC in ROM, and quite a few other things
      that 1802 fans would be drooling all over! Imagine getting this thing
      working again.

      If you do, I have a set of FORTH Inc. polyFORTH disks for this system. :-)

        The most useful thing would be the first couple of pages of code from mpm-207 the floating point routines. That would let me know if they're different from what i have today.

        Thanks very much.

        While I'm lunching with the scanner next week I'll slip in part of the timeshare manual.  That should at least give you a chance to see if it really is what you're interested in.

        Actually, I’m sorry to say, I haven’t begun.


        It wasn’t clear there was anyone interested so I didn’t start.


        The MPM-208 Ops Man for COSMAC Dev Sys is ~136 pages… that’ll take some doing.

        I think I may try cutting the staples loose and scanning it as 2 sided 11x17.  Unfortunately that’ll mean it is largely unreadable unless it gets printed out on 11x17, folded into 8.5x11 and re-stapled.


        The MPM-216 Ops Man COSMAC Dev Sys II 18S005 is a bit smaller @ 124 pages…  Same problem though.


        The other question is, while I have them, and am willing to scan them for the greater good, it is not clear that both are covered under the release obtained by Dave.

        In the case of MPM-216 the title - “Operator Manual for COSMAC Development  System II CDP-18S005” exists in the list but there is no mention of the title “Operator Manual for COSMAC Development  System” nor is it referenced by number as MPM-208.

        Dave lists the title, but not the specific manual number in his communications with Intersil.  Since RCA was in the habit of changing the manual number for newer releases there could still be some confusion.


        I’ll ask Dave to consider a more detailed listing of title and document number if he decides to revisit this with his Intersil legal contacts.


        I’ll also consider opinions for the gallery on these points.

        Hello Steve,
        I was wondering if you made any progress in scanning those manuals you spoke of.
        I am especially interested in:
        MPM-208,Ops Man for COSMAC Dev Sys,Sgemeny
        MPM-216,Ops Man COSMAC Dev Sys II 18S005,Sgemeny
        I have a COSMAC Dev Sys setting in my basement and would like to get it running again.
        I used to have all the COSMAC documents but over the years and several basement floods I have lost them.
        To run the system I have an 8" floppy Single Sided Single Density (SSSD) with RCA DOS 4.0.
        Probably the last one in existence.

        If I can get the system running I can make/contribute copies of the RCA DOS 4.0 to anyone wanting one
        if they supply the SSSD 8" floppy. They are hard to find.

        Really great news, and so fast!!!

        Perhaps collecting a list (CSV or Excel format) in the files folder (or
        GoogleDOCS or some other file sharing medium) we could all include our own
        holdings in the list and avoid duplication of scanning effort - all with
        one carefully contrived effort.

        In looking through my collection of RCA Manuals that I'd be willing to scan
        and contribute:

        Man #,Shore Title,WHO
        MPM-201A,Users Man CDP1802,Sgemeny
        MPM-202,Time Share Manual,Sgemeny
        MPM-206,Binary Arithmetic,Sgemeny
        MPM-207,Floating Point,Sgemeny
        MPM-208,Ops Man for COSMAC Dev Sys,Sgemeny
        MPM-212,Inst. Man MicroTerminal,Sgemeny
        MPM-216,Ops Man COSMAC Dev Sys II 18S005,Sgemeny

        Hi Dave,

        This is very good news. I'm impressed that it happened so fast and with
        positive results. I guess I was expecting much more red tape.

        Did this list include the RCA COSMAC Game Manual (original & II)?
