Hi,
I've also got an ancient Taiwanese one that
works only with
a PC XT that will handle 2708s.
That wouldn't be the "Sunshine" brand unit by any chance?
I've got one of those too (along with their PAL programmer from around the
same time) and it won't work in anything newer than an XT. :-(
Why is that a disdvantage _on this list_? Surely original IBM PC/XT
machines are not hard to find (are they?) and they're certainly repairable...
