doctorclu Posted November 20, 2017 Share Posted November 20, 2017 Back in the 80's my Dad enjoyed taking Apollo game cartridges since they were relatively inexpensive and used eproms and would rewrite them. I came across a Apollo cartridge the other day and it had a regular rom on it. So in anyone aware of the Apollo cartridge productions, when the eproms were used and for how long. Also any way to tell the eprom and rom productions aside from opening the cartridges? Quote Link to comment Share on other sites More sharing options...

AFAIK, if you see an off white board, it uses EPROM's, the green ones are usually ROM's. 1 Quote Link to comment Share on other sites More sharing options...
Tempest Posted November 20, 2017 Share Posted November 20, 2017 How on earth does it make sense to use EPROMs instead of ROMs in anything other than small runs? Apollo wasn't huge, but they were producing enough that that couldn't have been cost efficient to do that. Quote Link to comment Share on other sites More sharing options...

They were selling the PCB's to home tinkerers, via Jameco. 2 Quote Link to comment Share on other sites More sharing options...

doctorclu Posted November 22, 2017 Author Share Posted November 22, 2017 Here is the inside of one Apollo cart I am buying online. Yep, they used eproms in quite a few of them. Now a fun Thanksgiving meal conversation with Dad is how he found this out back in the 80's. 1 Quote Link to comment Share on other sites More sharing options...
Supergun Posted November 22, 2017 Share Posted November 22, 2017 This subject matter was actually how me & Wiz first met here. And the unfortunate subsequent miscommunication was what inappropriately led to incorrect assumptions which resulted in us thinking we weren't friends. What? Never mind!
