    Ok, it took a little digging to find a little bit of info on the 4663 "parameter entry card".

    Tektronix engineers were trying to invent a better way of configuring the interfaces than the switches...

    A photo from a Tektronix plotter brochure indicates the setup is done from the front - maybe behind the panel on the left of this photo?

    Alex,

    I have a working 4662 plotter, but don't know if the 4663 plotter has similar setup switches on the back the interface configuration.

    One of the vcfed users has a 4663 plotter - maybe he...

    legalize,

    I had them scan their microfiche of the Tektronix 4052 Assembler Program documentation.

    I just checked the spreadsheet inventory I did of Bob Rosenbloom's Tektronix documentation...

    This is my setup with my 4054A computer connected to my 4662 (with multi-pen Option 31), right after plotting Snoopy.
    You can read the first page of the program - it is all PRINT statements. PRINT...

    Any luck on getting your 4662 plotter working?

    I started a new vcfed.org thread on getting mine working with GPIB to my 4054A, and plotting "Snoopy - Red Baron" with an old plotter pen, and new...

    Tektronix 4662 plotter is Working!

    I finally figured out how to get my Tektronix 4662 plotter working with my 4054A computer using GPIB.

    There are four rotary switches on the back panel that configure either serial or GPIB...
  12. Latest Tektronix 4052 / 4054 Tape Dump Program

    I have been using the TransEra Super Utilities ROM Pack to recover all the files from a Tektronix 4050 tape including SECRET files with a single program.

    Someone may be able to decipher the...

    Jos,

    I understand :)

    My backlog of Tektronix projects includes getting back to work on the GPIB tape drive emulator with microSD card storage.

    I've been having too much fun with the 4907...

    Maybe Jos Dreesen can create a circuit board for the "Tektronix 4051/4052 Multi-ROM Pack"!
    Jos has already created a 4052 Diagnostic Cartridge, which works great in my Tektronix 4054!

    My github...

    Extending the 4051 ROM Expander idea a bit further - maybe the board should emulate the 4050E01 ROM Expander which supports both 4051 AND 4052/4054 ROM Packs.

    The 4050E01 ROM Expander...

    I agree.

    It sounds easier to just emulate the bank switching of the 4050E01 eight-slot ROM Expander and use two 32Kx8 or one 64Kx8 EPROM to store eight ROM packs. The 4051 Editor ROM Pack has...

    I ohmed out my wiring and found a couple of wiring errors and a bad jumper.

    I was able to read eight of nine MCM6832 ROMs! They were all over 40 years old!

    See my post:...

    I began ohming out my wiring and found mistakes and a bad jumper wire.

    I replaced my cheap DIP socket with a machined pin socket - rewired and was able to read all but one of the 4051 MCM6832...

  23. Anyone know how to capture Motorola MCM6832 mask ROMs with a Data I/O Unipak?

    I just received eight Tektronix 4051 and 4052 ROM Packs and I want to capture and upload the ROMs, but the 4051 ROM Packs have this MCM6832 2kx8 mask ROM that requires +5V, +12V and -12V.

    I've got...
