How exactly do PAL chips get programmed?

Rumor has it that Teo Zenios may have mentioned these words:

I have a programmer that can do older PALs and/or GALS -- not enough brains 
to actually use it, tho.[1]

Older PALs/GALs/PEELs can be had pretty cheaply at www.bgmicro.com (It's a 
US company, dunno what's available worldwide, tho they might ship 
worldwide... you'd have to ask them) - maybe someday I'll actually be able 
to figure out how to program some of those critters.

Hope this helps,
Roger "Merch" Merchberger

[1] I do know how to use my programmer for EPROMs, but I've never 
programmed a PAL/GAL before.
