Thread: HP Logic Analyzers - HP Pre-Processor Modules - HP Inverse Assembler

  1. #1

    Default HP Logic Analyzers - HP Pre-Processor Modules - HP Inverse Assembler

    I started this thread because I just received a set of HP Pre-Processor Modules and General Purpose Pod Interface for my HP 1630A and 16500B logic analyzers.

    I have three General Purpose Interfaces for the Pre-Processor Modules:

    1. HP 10269A General Purpose Probe Interface, for HP 1630A/D Logic Analyzers
    2. HP 10269B General Purpose Probe Interface, for HP 1630A/D/G Logic Analyzers
    3. HP 10269C General Purpose Probe Interface, for HP 1650A, 1651A and HP 16500A/B and 16510A Logic Analyzers, with Operating Note, August 1987


    Here is the list of HP pre-processor pods I have:

    1. HP Model 10269A General Purpose Interface, with Service Brief 10269-90901, printed December 1982
    2. HP Model 64683A Z80 Interface Module, with Service Brief 64683-90901, printed January 1983
    3. HP Model 64655A 8085 Interface Module, with Service Brief 64655-90903, printed January 1983
    4. HP Model 64653A 8086/8088 Dedicated Interface Card, with Service Brief 64653-90904, printed February 1983
    5. HP Model 64670A 68000 Interface Card, with Service Brief 64670-90901, printed December 1982
    6. HP Model 64681A Z8001 Interface Module, with Service Brief 64681-90903, printed January 1983
    7. HP Model 64672A 6800/02 Interface Module, with Service Brief 64672-90901, printed September 1983
    8. HP Model 10320C User Definable Interface, with Operating Manual, September 1987
    9. HP Model 50601A/002 AD & I 8031 Preprocessor with QFP cable, no docs


    I also have HP mini data cassette tapes for the HP 82161A Digital Cassette Drive with HP-IL (standard interface on HP 1630 logic analyzer) that are labelled as holding the inverse assembler software for the 8086/88, Z8001/02, 6800/02, and 68000.

    I will be scanning all the docs and posting links in this thread.

    Here is a photo of my collection of modules, tapes and manuals:

    Nice collection. I have a similar 646xx preprocessor collection minus the 64681A Z8001 preprocessor. I also have a 64671A 10308B 6809 / 6809E preprocessor.

    Quick work providing a nice quality scan. Thanks.

    Sometime I'll have to see if I can figure out how to feed a sequence of signals into the 6800/6802 preprocessor to extract the contents of the three PROMs without desoldering them.

    Thanks.

    I see that one of the PROMs is socketed on my 6800 module. Would it be easier to just unsolder the other two and try to read them on a programmer?

    One of the docs I received was an 'Appendix I' for the 6809/6809E module and 'Appendix J' for the 80188/80186 module. These appendixes include operation, but not schematics. The 6809 section helped me set up the ADDR, DATA and STAT configurations so I could load the 6800 inverse assembler into the 1630A logic analyzer from tape.

    Here is the 6809 signal list:

    Pod 4 J CLK
    Pod 4 K CLK (I didn't configure either of those manually)

    ADDR A0-A8 Pod 2 0 to 8
    ADDR A9-A15 Pod 3 0 to 6
    DATA D0-D8 Pod 1 0 to 7
    STAT Pod 4 - I configured bits 0 to 3, their table shows all 8 bits are used for the 6809 inverse assembler

    I'll scan this appendix next

    I'll have to look at my 6800/6802 preprocessor and see if any of the PROMs are in sockets. If they are that would be the easiest way to dump their contents.

    I also have an original copy of 'Appendix I' for the 6809/6809E module and 'Appendix J' for the 80188/80186 module that I never got around to scanning.

    I also have an original copy of Helwett-Packard Model 64671A 6809/6809E Interface Module Service Brief, 64671-90901, December 1983. That includes a schematic. I'll have to scan that one sometime.

    New document - Service Brief for HP 10269A General Purpose Interface for HP 1630A/D Logic Analyzers:

    HP Model 10269A General Purpose Interface, Service Brief 10269-090901, December 1982

    From this document, I should be able to create a POD connection table for the 10269B General Purpose Interface for HP 1630A/D/G Logic Analyzers, by looking at the decals on top of the 10269B.

    Do you not have a copy of this one?

    Hewlett-Packard Model 10269A General Purpose Interface
    First Printing, December 1982, 10269-90902
    Second Edition, January 1983, 10269-90903
    Third Edition, July 1983, 10269-90904
    Fourth Edition, October 1983, 10269-90905

    I have an original copy of the Fourth Edition, October 1983, 10269-90905 version.

    It includes these to go along with the Appendix I and Appendix J supplement you have:
    Appendix A: Interface Module Z80
    Appendix B: Interface Module 68000
    Appendix C: Interface Module 8085
    Appendix D: Interface Module Z8001/Z8002
    Appendix E: Interface Module 8086/8088
    Appendix F: Model 10269A Options for Making a User Definable Interface
    Appendix G: Interface Module 6800/6802
    Appendix H: Interface Module NSC800

    Those include the module specific POD format specifications for the 1630 series analyzers.

    I'll have to scan that one when I have time. I haven't found a copy online anywhere.

    No - I don't have any of the newer versions of the 10269A documents. I would think scanning the Fourth Edition and Appendixes would be fine.

    I entered the 6800 configuration screenshots from your eevblog post on the Inverse Assembler, saved the logic analyzer state, then was able to load it back successfully, although I had to manually edit the User Symbol table on my 16500B to select Binary mode. Were these the only STAT symbols for the non-preprocessor version of the 6800 IA? I see sixteen different STAT symbols in the 6800 Service Brief.

    I used the HP 82161A HP-IL Cassette Drive and a couple of HP-IL cables on EBAY, and was able to load a 6800 Inverse Assembler into my HP 1630A.

    I also purchased a "PIL Box" http://www.jeffcalc.hp41.eu/hpil/#pilbox and hooked it up today to try to capture the Inverse Assembler files.

    I used the ilPer program to 'scope' the HP-IL messages, while doing a tape file copy.

    I could easily see that the file data was continous DAB xx hex output, so used Notepad++ to edit out everything but the Hex characters, then used a HEX to Binary file conversion online tool to create the binary files. I then checked each of those binary files with HxD and they appear to be IA program files.

    I haven't figured out how to get my PC to use the PIL Box to emulate a tape - instead of the HP 82161A cassette drive, nor figured out how to put these files into a format to use with the PIL box, but I'll do some more experiments.

    Here is a link to my zip of the IA files that I believe will work with HP 1630 series logic analyzers. I have only loaded the 6800 file from tape but not used it yet.

    Is that what 6800 CPUs are for? I have spares of those and don't know what to do with them.

    Let me know if you need more HP-IL cables, I have several extra.
