Hello, I\'m considering building a GAL programmer featured in the May 1994

Thanks for any help

Don\'t waste your time and money on that antiquated crap.

Do this:

Then check this out:

and all the ICs it handles:

- a lot more bang for the buck.

Those DIY programmers may not even be spec for all the GALs- means you get a quirky chip.

If you build a system using a significant number of them, you better think about bringing out a representative sample of signal on header connectors to be captured by a logic analyzer for debug, or even a self-diagnostic.

Depending on your goals, you can likely find a moth-eaten
copy of CUPL, ABEL or PALASM if you looked hard enough...

(Or, something more \"current\")
