Yes, and yes 5V power supply too.  Get a  Digi-key  catalog  for details.
The old MMI pal design book, had a 300? buad terminal all 20 pin fuse

You are limited to 64 I/O pins with the Atmel CPLD's I am using -
84 pin plcc's. The big problem is none of the PCB design programs
have a thu the hole plcc footprint that I know of.
