 Original MOS Technology 906114-01 PLA chip for the Commodore 64 computer.

This is a genuine vintage Programmable Logic Array (PLA) used in the Commodore 64 and C64C. The PLA is a critical custom logic component responsible for address decoding and memory control, coordinating access between the CPU, RAM, ROMs, and I/O devices.

The PLA is one of the most failure-prone and sought-after chips in the Commodore 64, making original working examples increasingly rare.

I’m happy to offer combined shipping. If it doesn’t work for you for any reason, please feel free to contact me.

If you add multiple items to your cart and try to request combined shipping but it doesn’t work, the first thing to try is logging in to eBay.com and making the purchase from there, then requesting combined shipping from that site.

Regardless of this, if it still doesn’t work, I will always partially refund the shipping cost, and I’ll be happy to combine the shipping for you.

Due to the currently ongoing U.S. customs restrictions, unfortunately I have to ship to the United States at a higher cost. Thank you for your understand!
