Hi Adrian, keep up the interesting work! Are you aware the 68764 EPROM is a drop in replacement for the 5150 masked ROM? No adapter needed. I worked at Mostek in the Telecom department and I was wondering if you realize that some 4116 RAMs require other voltage in addition to +5? The MK4116 was a 5 volt only device but not so with the original Texas Instrument device. Maybe that is why you have some failed RAM. I have the company data books if needed. I enjoy watching your videos!
