Hi Alex
 8702A is mostly the same as a 1702A and can be programmed
with any programmer that supports 1702A. The only difference
is that I know of was that the threshold for data was
a slightly different voltage. The 8702A was designed to
tie directly to a 8080 or 8085 without additional buffering.
Otherwise, the 1702A spec will work. If y9ou want the
exact levels, I can look it up.
 Most current programmers do not support the 1702A's. You'll
need to find an old programmer someplace.
