Well, I find it interesting, if for no other reason than I have a pair
of 27C512s I'd like to reprogram (new version of BTS6120) and I did not
happen to bring my programmer with me. No, there does not appear to be
an EPROM programmer for at least 850 miles, if not 3000 miles.
I don't know that I'd construct my own here, but I probably could. We
have adjustable bench supplies I could use for the programming voltage
(meaning I don't have to roll my own); all I need is a way to cycle the
address pins and to read/write the bits (since I would really like to
verify the parts before and after).
I do have several device programmers at home, a full-sized Data I/O unit
with about 8 ZIF sockets, a Bay Technical Associates serial-interfaced
unit, a B&C Microsystems UP600A, a Promenade (for the C-64), and a couple
of SBCs with built-in EPROM programmers (Z-80 Starter Kit...) None of
them were small enough to be worth the chance I'd need one down here, so
now I'm stuck.
One thing holding me back - no way to erase the parts I have with me...
I can't even use the trick of concentrating sunlight. :-)
I have a couple of "ultraviolet" LEDs with me, but I doubt they are the
right frequency to erase EPROMs.
