The OLD Pre-Unisite (model 2900 ??) programmer from DataI/O was what I used
many years ago to program both the 5203 and the 1702. Surely they haven't
entirely skipped those in the course of moving to the UniSit?, or have they?

Can you program 1702A's?
Unfortunately not. The UniSite is a good machine, and since it's
pin-driver technology could probably be made to do it, but Data I/O never
developed an algorithm for the 1700 series parts that I'm aware of.
How about the similar National part 5203? Both
are
256 Byte EPROM's. There was also a Motorola part, 6834(?).
Neither one is listed on my device chart, so I would have to say no. Sorry
about that. The problem is that Data I/O keeps information about how to
actually program the UniSite's innards a closely-guarded secret, so I have
no way to even try to cobble something together.
