I'm not sure how device support on the 29xx/39xx
compares to Unisite, but the only old programmable devices I've found that the Unisite
doesn't support are the first generation EPROMs (1702, 1702a,
5203, 5204), due to these needed rather extreme programming voltages (e.g., -40V to -50V)
on many pins (not just one program pulse pin). The Unisite does support most bipolar
PROMs, while most modern
programmers do not.
Just checked, and the earliest parts a 29xx/39xx will program is the 2716, ie. they
don't support 2708's.
