Thread: Tektronix 4052/54 diagnostic ROM pack remade.

    Jos,

    Cool lettering on the inside of the base of the Diagnostic ROM case.

    I can barely see it though the case in your photo - cool! Did you print in PLA or ABS?

    I used white, semi-translucent PLA. Works quote well, better than you can see in the picture.
    Would be a nice experiment in a dual-extruder machine, alas I do not have one.
    i added the openSCAD source file for the cases to the FTP site, in case you'd like to fool around with it.

    Generally Firefox should enable you to download files from my FTP server without problems. Never tried to use IE .

    Jos,

    I decided to try to make a 3D printed overlay label with raised letters according to your photo in the PDF.
    It should be easy to print and then color the text and glue to the base, instead of trying to get labels to stick to the base.

    I imported your base STL in Openscad - and found a post that tells how to add embossed letters.

    Here is a link my ASCII STL file:
    https://drive.google.com/file/d/1AOJ...ew?usp=sharing

    and here is a screenshot of the overlay in Simplify3D:

    Thanks for all your hard work to replicate this diagnostic board!

    Monty

    PS - I updated the link to a newer STL with slightly larger fonts
    I just printed it in ABS on my Ultimaker2+ at 0.1mm layers

    Thanks Jos!

    Just sent you an email. I should have no problem getting the parts apart from the programmed GAL; my old Data I/O predates those by a wide margin.

    Diagnostic ROM Pack test results on my 4052.

    All the tests passed. I also ran them individually as BASIC CALL statements, so I could take photos of ROM CRC, RAM and ALU tests.
    My post on this is in my 4052 troubleshooting thread:
    http://www.vcfed.org/forum/showthrea...383#post516383

    Here is the CRC Test result:

    Thanks for the great board - Jos!!

    Default 4052 ROM Cartridge CRC Tests

    After fixing the 7405 inverter issue - I decided to use the Diagnostic ROM Pack to check the CRC for three 4052 cartridges I purchased from Stan back in 2000.

    One cart was labeled Character & Symbols, and two said FFT2 on the label on the end - however one of those had an NII label where I had handwritten a note that it was a 4907 File Manager cartridge for 4052/4054!

    I turned off power - plugged a cart in slot 2 with the Diag Cart in slot 1 - configured to run the ROM CRC test
    I then turned on power and the ROM CRC test would immediately run. If the unit was off very long, the text would not be clear and I would quickly cycle the power.

    The additional ROM Cartridge CRC would be listed after the Diag ROM CRC - as shown in these screenshots:

    Character & Symbol:

    IMG_6748.jpg

    FFT2

    IMG_6750.jpg

    4907??

    IMG_6752.jpg

    Sure enough the Character & Symbol checked OK and the FFT2 was OK, but the suspicious cart CRC was not the same as the published 4907 CRC.

    I opened that cartridge and the board said "16K ROM Pack"

    Here are photos of both sides of the board and my handwritten note on back of the cartridge:

    IMG_6754.jpg

    IMG_6755.jpg

    IMG_6756.jpg

    I then downloaded the bitsavers 4907 User Manual - and tried a couple of the CALL statements in the test program on page 4-1: CALL "TIME",R$ and CALL " UNIT",1 and CALL "DRES",1

    without any cartridges plugged in - those were all invalid CALLs

    with the suspicous cart - the last two calls just returned with no errors. The CALL "TIME" returned with a GPIB error.

    So that cart might have valid 4907 code - maybe early development code?

    Hi Jos and all,

    just wanted to confirm my DRP works as it should! That was an easy project for a change.
    No RAM or ALU errors. ROM CRCs differ for the missing chips (PLAs, patch ROMs) on the rev9 MAS, which I may not be an issue.

    Many thanks again for putting this together in your spare time!

    The 4907 ROM PACK requires the 4907 File Manager to be attached to the GPIB for the functions to work, otherwise they will just return the errors that you were getting. Can you post a dump of the 4907 ROM pack? I'm looking for the 4051 version, but I would like a copy of the 4052 version. I'm trying to build a library of all of the 405x series ROM's.

    oldcomputerexpert,

    Ok - I found my 4907 cartridge ROM dumps - and document I made in April 2000 on how I did the dumps and some info I derived from the Hex files (ROM entry points and CRCs).

    Thanks! Now I just need to find the 4051 version of the 4907 File Manager ROM Pack....
