Default Re: A Simple Programmer for TESLA "MH74S-" bipolar PROMs

Here's the full-size circuit (20mins with a drafting pen).
There was an (obvious?) omission from the posting: "PROM address lines are same as parent SoC circuit."
I'll sketch out the programming voltage timings used in the SC/MP code and post soon.
I have now coded a TESLA version of the SoC Promblower but not yet tested it.
