This is an offshoot of the R2 CPLD project that I did for a Hackaday video that makes it easier to support 3.3V and 5V CPLDs. Also connects an additional I/O line or two and adds a reverse protection diode.
Altera 7064 CPLD w/ 64 Macrocells , 28 I/O lines and 3 dedicated inputs in a 40 pin .6" wide DIP module. 5V or 3.3V
