Which tools are you referring to, Allison?
I've found that the tools I once used with the old (pre-1990) 2064's, don't
work with the 3000-series, and, though I have some 3000-series parts (which,
back when I bought them, cost about $200 each) I've not figured out a way to
program them using the old XACT or the more recent "Foundation" software.
They clearly are no longer supported with current software.

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

that's another $8.40. Now
find a
cheap
wirewrap board to which you can solder ... and then use the free
software and build the ~$5 ISP adapter.
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.
