    FREDDY REPLACEMENT  -   You must have installed SRAM MODULE first !!!

     

    • Creates OSC clock (3,5X MHz) for GTIA  (CLK_IN /4)
    • PAL/NTSC independant
    • Gnerates inverted CLK_O for some motherboard revisions
    • CAS_IN for SRAM MODULE CONNECTOR ONLY

     

    STEP BY STEP:

    • swap FREDDIE CHIP with replacement
    • connect wire form LSP1  to CI (cas_inhibit signal on rev 2)  SRAM MODULE
    • after power_on, clk_led shall be constant on - it means we have nice square clock signal :-)

    to do:

    • FIT SRAM REPLACEMENT
