trying to read it as a 2732? Looking at the pinouts it looks like the only
difference is pin 21 which is Vpp (programming voltage) on a 2716 and A11 on
a 2732.

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

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

It definitely does seem strange. I wonder if maybe it’s a TI style 2716? It’s a
National Semiconductor MM2716Q.
