All zeroes is really strange - a blank EPROM is all ones, so it?s not that it got exposed
to UV light.

Found a single 2716 EPROM on the Altos and pulled it out and read it in with my MiniPro
TL866CS and it comes back as entirely 00. Since that seemed pretty odd I grabbed another
2716 out of an old Nintendo board and it reads fine, so I'm pretty sure the TL866CS
can read 2716.
I have a feeling the Altos isn't going to work without proper data on the EPROM. :-)
I guest the first challenge is getting a copy of what the ROM is supposed to contain, and
the second will be burning it. Anyone happen to have an image of the ROM for an Altos 8500
board?
