According to the datasheet (page 89) it says that thanks to the "Multi-Volt" tech inside, this CPLD is fully compatible with 5V TTL logic without the need for external resistors. It says for CMOS it would need pullups, though.
So, my question is do these old 5V game consoles all run at TTL levels, or is there a list somewhere showing what runs on what logic?
