Default Re: Tesla Programmer

Hi OS, nice to see you are still around. I think one of my two programmers here may support Texas SN-series BPROMS but I will have to look to see if that includes the SN74S287.

I have to say that we all appreciate the investigative work by you and Chris, also circuitryboy who worked on the problem independently - I suppose no matter how careful you are, when you are working with one-shot devices you must have to waste a few while fine-tuning things so there would have been a cost in terms of parts as well as time, Although I suppose you could minimise that a little by only trying to programme individual bits at a time in the early stages of testing, rather than the whole device.
