Re: M2716A-2F1 datasheet

Well fortunately, these eproms have 21V written on the top of them so
it's not hard to miss. I'm using a Dataman-48Pro+ where they give you
the specs of a generic 2716A and yes it's set to program at 21v. I'm
not sure if there's anything special about STMicro's. Normally what I
do is try to find the datasheet, send it over to Dataman and they
usually fix the problem. But I can't find a datasheet anywhere on the net.

There's also the possibility I have some bad devices. :| I only did a
quick search but I don't think the Data IO 29B does them either. I'll
double check. I'd love to find a datasheet though.
