The PLA264 is a replacement for the MOS 251641-02 PLA chip used in Commodore's TED-based 8-bit computers, the C16, C116, and Plus/4. It is an alternative layout to the PLA16V8. Like the original, it is based on the GAL16V8 and it requires the same JED file for programming. Unlike the original, when properly assembled, it is small enough to actually fit into the case of a Commodore Plus/4 without issues.
