Hi there,
I am currently in the unlucky situation of having to duplicate two different 74ALS188 (32 x 8) bipolar PROMs to a whole bunch of a dozen new 82S23 bipolar PROMs. Unfortunately, I don´t own any programmer which is capable of handling such bipolar PROMs. Well, is there any affordable homebuilt PROM programmer available on the net which can handle 82S23 PROMs? Any hints to schematics and PCB layouts are highly appreciated.
TIA Joachim.
