It's a long time since I used GALs, probably 18 years. From the back of my memory I remember entering boolean equations. Try googleing something like 22V10 which if my memory serves me well is a 22 input 10 output versatile logic array (I'm sure I got that wrong).
The original PAL devices were "programmable array logic". But, they were either active low, or active high, but not both, and either registered or combinatorial, but not both. Then the GAL appeared. Each macrocell could be individually configured as active high or low, as well as combinatorial or registered. You can mix and match, making these new devices truly "generic". Hence the acronym "GAL" was coined, meaning "'generic' array logic".
