I built and used the Galblast for my own GAL based projects with 16V8 and
20V8, and it works fine. Building it is a pain, because you really need a
circuit board with through-plated holes, otherwise the device will be
unreliable. Ask me, I etched the board myself and sometimes it will not
work, then I have to go looking for the bad connection ...
So if you're going to have a few boards manufactured, I surely would want
one of those, too :) And I'm sure other will also take one.
Things the GALBlast can't do:
- preloading of registers for automated testing with test vectors
- reading of copy protected GALs (but which device can?). Maybe uses
register preloading anyway?

I used Atmel WinCUPL as well, but don't remember if I had to register. I
surely didn't have to pay for it.
