I have an old Apple //e clone, bought in Brazil (but assembled who-knows-where-on-Earth) that has not been touched for over 15 years.
At least, from what I could see, it is a //e -- but not enhanced, since it has lowercase characters, but came with 48k RAM (is that correct?). When booting, instead of "APPLE ][", "APPLE //e" or any clone brand name, it prints "COMPUTER" on the screen (now that is an informative message!)
When it was working, I remember the character generator had some problem (some characters displayed kind of weird on screen, with some pixels missing sometimes, but not always). So I was wondering if I can dump its content, maybe debug and fix it, and put a new EPROM in its place. But I don't know what kind of EPROM it is -- there is no useful information on it, and all I can see is that it's a 24-pin chip, with the round hole in the middle for recording.
What IC could I use to replace that one? And what kind of gear do I need to dump the old one's contents and write the new one? Would a MiniPRO TL866CS, for example, do the job? (it's easier for me to get a MiniPRO than any other EPROM recorder)
