Programming 2708's - test-drb@ccmp.vtda.org

Dwight:

	Actually what I'm going to do is build a few adapters for different
24-pin densities such as the 2716, 2732 and the 2532. I have a few tubes of
2532s so I'm going to try those by mounting a socket on a DIP header and
making the wiring changes between the two layers.

Hi Richard
 I have both a Byte Saver and a data I/O. If you'll send
me the EPROMs and the data, I can program them for you.
 As was mentioned, It wouldn't take much to make an
adapter out of two machine pin sockets that could take
2716's to use in place of a 2708. Most of the pins are
the same. Just make sure to pull the pins that provide
the extra nasty voltages.

All:

	OK, I'm ready to burn a modified copy of the Altair Turnkey Monitor
into a 2708 to use in my 8800b as a test program. Lo and behold, my
programmer won't do a 2708 -- it'll only go down to 2716. Naturally I don't
have any 2716s around and the VG ROM board accepts only the 2704 or 2708
(without modification).

	So I browsed around eBay and elsewhere to see if any other
programmers support the 2708 and it seems that none do. They all start at
the 2716.

	What programmer can I look for that has the ability to program a
2708?

	Thanks.
