That second sentence is not mine--I don't know where it came from.
In fact, the only reason that I can think of to use 2708s (or even 3-
supply 2716s and 2732s) is historical accuracy.
For that matter, why bother with UV erasers and UV EPROMs at all?
There are plenty of good EEPROMs around that are easy to erase and
simple to program. Flash is even better, with boot block features
and the ability to be partially programmed. And there are some
moderate-capacity nonvolatile technologies, such as FRAM that should
do very handily in most designs.
