Wow - Featured on Adrian's Digital Basement ][ YouTube and thanks for looking,
This is special "compact" version of the "PLA20V8".
The schematic is based on the popularopen source project(url removed due to policy, google "PLA20V8" instead)I developed the PCB to make the project compact and to match the look of the replacement IC similarto other ICs on the Commodore PCB.
I covered this project development on my YouTube channel:(url removed due to policy, google "SlimPLA C64" instead)
I used high quality black PCBs from PCBWay andthin pins to protect DIP sockets in your 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
By buying the PCB from me, you're supporting the original "SlimPLA" designer and great future open-source project :) Many thanks!
