I've done this with other similar packaged devices and it flies.

find a

Has anybody done that? I have a nice FPGA prototype kit, (altera) but I am
having problems
getting A PROM for it. I may go to using smaller chips like the XC-9572
(72 macro cells) ? $12 canadian. They don't make wire wrap PLCC sockets
What prom are you looking for?
I'm still playing with some 2064s and 3030s and 3050s, yes they are old
but
the tools were free, the parts cheap and easy to load up with a 2816/64.
