PLA for Commodore Plus/4, 16, 116


THE ULTIMATE PLA

Commodore 16, 116 and Plus/4 replacement for PLA Programmable Logic Array 251641-02 

The problem:
faulty PLA can cause: Blank screen, no border, colored screen or flashing color garbage instead of startup screen, intermittant loss of cursor, screen freeze and/or program crashes after warmup or random characters on screen.
The original chip 251641-02 runs very hot and is very poor reliable. This is the first cause of problems on Commodore computers.
Replacing the fault PLA with an original chip doesn't fix the problem definitely due to their poor reliability.

The solution:
This chip is based on a new technology programmable logic arrays chip that reproduce exactly the functionalities and the timing of the original PLA.

It's compatible with all board versions.

Please note that a replacement based on a generic eprom technology can cause instability problems and incompatibility with particular cartridges

It's the ultimate solution for PLA replacements:
- it runs cold
- low consumption ... very low dissipation ... also for the internal power supply
- it is reliable (it will never burn)
 
This chip reproduce completely the internal logic and the timing of the original PLA !!!

High quality item, manufactured with high quality PCB.
It's possible to insert directly in the PLA socket. Compatible with normal or turned sockets.
 
Tested and working !!
I ship worldwide with or without tracking number.
