serial. It was fun to see peoples faces when you shipped a ^C down the
serial line, and dropped through to a READY prompt.
I can find the doco for yo, but it is a high end solution to a simple
problem.
Alternately, I'm more than happy to read an eprom for you, and email
contents - I'm in Oz though. Perhaps there is somebody in the US who
could do the same.

As 2708s are
obsolete few moern programmers support them, apart from a few
that cost many $100s. So I thought why not try and build one? I've found
references to the following classic magazines, and I would be willing to pay
a small fee for photocopies or scans of the articles:
Program your next EROM in BASIC. Schematic for a 2708 erasable read only
memory reader and programmer which uses parallel IO ports to set data and
address. The software to drive the programmer is written in BASIC.
