I believe it stands for Generic Array Logic. It is similar to a PAL
     (Programmable Array Logic), but since it uses an EPROM, EEPROM or
     Flash to set the block connections, it is reprogrammable, unlike a
     PAL, which is OTP. A GAL or PAL is a bunch of logic gates and
     registers in an IC package that can be interconnected by setting bits
     in the EPROM. GAL's are typically used as 'glue logic' to replace many
     individual SSI devices, or to create special purpose registers or
     modules that don't exist off-the-shelf.

     Hope I didn't use too many acronyms for you.

Question: What does GAL mean?
Please forgive me if it is a stupid question but I'm not sure what this means.

                just uploaded to our ftp server schematics and
source/object/exe files for a DIY GAL programmer.
