Re: A Simple Programmer for TESLA "MH74S-" bipolar PROMs
The forum engine downsizes uploaded images quite aggressively and the circuit diagram for the hardware (in post #5) has ended up quite small and low-rez.
If possible, could you please post that diagram again, but this time put it into a .zip file and attach that, so that it can be unzipped and viewed in its original glory - it's very neat, by the way, it looks as though it has been drawn with hand stencils or with a computer drawing package designed to produce a result which looks like it has.
I think I have a tube of 74C906 ICs rescued from near-oblivion at work, if anyone wants to have a shot at putting one of these together.
