Is it possible to obtain programmed 74S288 PROMs for the H949 Harmonizer?. I have an H949 in which pin4 of PROM #8 is giving a bogus output. Alternatively, armed with a binary, I could create my own using a fast EPROM of flash chip.
I can help you with the PROMs and have the mapping at each address if you wanted to roll your own. Some proms were programmed differently depending if they were in a 949 with the DeGlitch board. Let me know if you’re still needing this. Best, Ben
