Commodore 64 PLA C64 SX64 Replacement 906114-01 - uPLA V2.0

This is a 906114-01 uPLA with high precision pin headers

If your Commodore C64 displays a black screen or strange characters then the problem could be the failure of the PLA U17 (MOS/CSG 906114-01)
But remember that most of the time the problem depends on the PLA but to be sure a test with the "DEAD TEST" cartridge should always be verified, because other components cause black screen / strange characters (RAM,SN74LS257,ecc)
I have made even this DEAD TEST CARD  (check my Store)



TESTED and Guarantees 100% compatibility and operation with the following ASSY MOTHERBOARDS
- KU-14194- 326298- SX-64- 250407- 250425- 250466


DETAILS

Professional & industrial PCB quality

Extreme layout,the smallest uPLA replacement (35mm x 17mm)

Equipped with precision pin headers to plug on your motherboard socket U17 position. Pins  are 0.018" (0.46mm) to ensure they do not cause extra wear on your socket. Gold plated to ensure the best possible contact

PCB designed for double Vsupply filtering

Tested with Super Zaxxon and Epyx fastload cartridges for full compatibility

Timing and CAS->CASRAM delay measured with AGILENT Oscilloscope : 30ns instead 29ns that is the value of original Commodore PLA  

Ultra low consumption at 7,5mA  compared to

a) 90mA for original PLA
b) 70mA for GAL20V8 based PLA
c) 20mA for Xilinx XC9536XL based PLA
