why don't you program a 705 with serial IO code, and make a pc board with
a RAM (instead of an EPROM). You could download S records to the RAM, and then
initiate programming of the part from the RAM. A 705k1 is small and cheap
enough to handle the task. I can get 19.2 kbps on one, which is fast enough.

BTW, does anyone have a summary of the 6805, 68705 etc series? There seem
to be a lot of them. The specs in secs disk doesn't mention the 705k1, the
705j2, or the 705c9.
