Re: RASTER: M2716A-2F1 datasheet

I also have the Data I/O 29B with Unikpak (and the logicpak) but I don't
think it programs the 2716a's which require 21v - but you're right it's
a pretty reliable beast. I just wish it fit nicely in my desk drawer
like my Dataman does.

Anyway, after reading this discussion
<http://www.eevblog.com/forum/chat/what%27s-up-with-2716-eproms/> I
decided to try reprogramming a couple of times and it finally worked.
