Some old school instruments showing how it's done (HP 3325A and Fluke 8506a)
joeqsmith:
From this datasheet, it's 232 ohm 1% 0.125W +/-30ppm. I let it run overnight and it looks like the p-p error is 2.3mohm with a standard deviation of 0.35mohm.

So I got the Batronix programmer, took 4 days to ship in from Germany.
....
I tried both Intel and TI NMOS 21V chips, and both worked first time.
Bottom line, it works like a charm... I feel it is good value at EUR 159, given the obvious care and attention that has gone into everything (hardware, software, and chip database that goes into extreme detail, even listing the EPROM variants with different timing).

So you can install these parts into the meter now and they work (meter boots and everything appears normal)?

Same ShallX part with the HP34401A, using cables shown, 100PLC.

Yes, everything works perfectly so far across 4 different controllers, using Intel and TI branded 21V EPROMs, and one pair of Intel 12V EPROMs (the latter also worked fine with TL866).
The Chinese minimalist eprom eraser also works like a champ, 20 minutes to zero the chips.
joeqsmith:
What's the plan now? Do you have a goal in mind for the old meter?
I checked eBay and there are a several with what I would consider some very crazy asking prices. Maybe they are collectibles. :-DD
I like this one for about $900.00 with tax and shipping. "Works", I know what that means. :-DD
