    As follow up to earlier questions, the 4702A and 8702A were the MCS-4 and MCS-8 equivalent numbers for the 1702A. Electrically they are identical.

    Hugo -

    The BK Precision 867C does specifically support the Tesla (MH) parts, and I've used it to program them successfully. That's actually the reason I grabbed this programmer as the Tesla...

    I have a BK Precision 867C that will program most bipolar proms. The MMI 6301 isn't listed, but most equivalent types (82S129, 27S21, 74S287 and 24S10) are supported. If you don't care about the...

    The TL866A is worthless for 22V10's and 2716's. Trust me, I've wasted way too much time trying. They often render 22V10's dead, and when they appear to program the parts won't work properly. They...

    They don't do much, but are fun to play with. The tiny basic in rom is pretty simple (eg, no FOR/NEXT loops) but was useful for simple control purposes and the Z6132 can be replaced by an Eprom once...

    I built an interface for the Praxis 35 using 4066's wired to the keyboard matrix. It was slow (especially on carriage return) but worked nicely.

    I do have a handful left.
    I've been asking $40 for an assembled, tested unit with midi cable and 3D printed case (plus actual postage). Less if you are looking for more than one.

    Happy to program, but I'm in the USA so shipping may be costly....

    I also have two of the Micromint Z8 basic boards, and probably have the documentation here too. The psudostatic ram was an interesting feature of that board.

    The IBM Thinkpad T42 also works nicely.

    I've never been able to use the EMP20 with anything but a "real" LPT. No luck with any of the Needham programmers and the USB<-->LPT adapters.
