Hi and thanks for looking, 

This is special "compact" version of the "PLA20V8".

The schematic is based on the popular open source project (url removed due to eBay policy, google "PLA20V8" instead)

I developed the PCB to make the project compact and to match the look of the replacement IC similar to other ICs on the Commodore PCB.

I covered this project development on my YouTube channel: (url removed due to eBay policy, google "SlimPLA" instead)

I used high quality black PCBs from PCBWay and thin pins to protect DIP sockets in your C64.

Professionally assembled and tested on ASSY 326298 motherboard - but the project is unchanged from the original published by Daniel so should work on all except for the short board ASSY 250469
