    Default Tektronix 4052/4054 Multifunction modules available.

    So I created a mutifunction module / ROMPack for the Tektronix 4052/4054

    - This covers the ROM-expander (Tektronix 4050E01) functionality in that it allows the equivalent of up to 8 ROMpacks into a single ROMpack module. ( Actually 16, if the TEK would have been able to handle that...)
    - One of these can be the equivalent of the Transera 741-RTC module. ( This is verified working ) Not Y2K compliant !
    - and one of these can be the equivalent of the serial printer interface. (functionality to be tested when PCB's are back from the fab)

    For good measure there is also the possibilty to add a reset button that will reset the whole machine.

    The 8 ROM images are combined into 8 16K slots in a 27c010 Eprom and can be choosen at will. If RTC and / or printer functionality is not required, then you can just not populate these devices, and use the freed-up space for other rom images.

    That is what it looks like :

    Sorry 4052/54 (-a) only, the 4051 will need a slightly different PCB, but ready to help out if some 4051 owner wants to try out things !


    Key components :

    27c010 Eprom ( ROM images)
    22V10 GAL (system decoder),
    DS12885 chip ( or DS12887 module) RTC,
    74ls580 (sub-second timer)
    MC6850 (ACIA)
    SN75155 ( 2x, line xref)
    74hc4040 baud rate clock divider,
    74ls173 (bank switch latch)
    74ls245 (data xfer)


    Who wants a PCB ( 15 $ ) ?
    a set of the above components (China-sourced, approx. 30$) ?

    I'd rather not create full kits, nevertheless if that is what you want, shout !
    And who needs build & tested PCB's ( approx 70$) ?

    ( all without shipping that is.... )

    Oh yes : Tektronix 4052/4054 diagnostic packs (equivalents..) are still available !

    Jos,

    Put me down for three PCBs and three sets of components.

    By the way - here is my list of Tektronix 4052/4054 ROMs that I've posted to github that could be put into a 4052/4054 Multi-function ROM Pack:


    1. 4052/4054 ROMs that could be put in a 4052 Multi-function ROM Pack include my posts of:
    2. 4052 Editor
    3. 4052 GPIB Enhancement (one for 4052 and other for A-series)
    4. 4052/4054 File Manager (for 4907 Floppy Drive System)
    5. 4052 Graphics Enhancement (fast graphics & music!)
    6. 4052 Character and Symbol (scalable vector character sets)
    7. 4052 Advanced File Manager (for 4909 Hard Disk System)
    8. 4052 RS-232 Printer Interface ROM
    9. TransEra RTC ROM
    10. TransEra Super Utilities (I use this one for tape backup/restore including binary and secret files)

    And for those with 4051 computers, interested in working with Jos on a slightly different board and components, here are some 4051 ROMs I have posted that could be put in a 4051 Multi-function ROM Pack:

    1. 4051 Binary Program Loader
    2. 4051 Editor
    3. 4051 Matrix Functions
    4. 4051 RS-232 Printer Interface
    5. and Clay's TransEra RTC ROM (hardware design could be incorporated into 4051 MFM ROM Pack board

    That's 9 roms... which one will you leave out ?

    I would leave out the 4052 Editor. If I'm editing a Tektronix 4050 BASIC program, I use Notepad++ on my PC

    Jos,

    I have cross posted your Multi-function board to the "Tek 4051 BASIC" facebook group.

    Ruben Aparicio in that group is interested in a 4051 version of your board, but is unable to register here.

    Jos,

    Some of the folks interested in your multi-function ROM Pack don't have 3D printers.

    They might also be interested in ordering a case for the ROM Pack.

    I just scanned and uploaded my manuals for the TransEra 741-RTC real-time-clock ROM pack for the 4052, and the 4051/4052 Option 10 Printer Interface ROM Pack to my github repository for Tektronix 4050:
