  • C64r MK2 s-video gives monochrome screen and heatsinks question

    Thank you for the replies!

    It was indeed a cable issue. I purchased an S-video to scart cable and it works like a charm.


    Unfortunately I now ran into another problem. It appears one of the 6526 chips is defective as my joystick keeps going down, even when no joystick is connected.
    When I swap the two 6526 between CIA#1 to #2 the C64 won't even boot and give a garbled screen.


    Are there any tricks to clean up the pins of the chip or do I need to look for a replacement? (mind you, I don't have a multi meter or knowledge on how to use one)

  • C64r MK2 s-video gives monochrome screen and heatsinks question

    Hi,


    First of a wonderful product! I had given up hope of seeing my c64's ever running again!

    Unfortunately I ran into some problems which I hope you can help me with.


    I have equipped all the needed chips salvaged from my old C64's.


    Config:

    VIC-II: 8565 (75 00 AF61 PAL)

    SID 1 : 8580 (DF 00)

    SID 2 : Unknown (14 00)

    CPU : PHI2 OK (0451)

    MCU : 20180227


    I have put the c64r into a c64c case. This one comes with a metal sheet as heat sink. Unfortunately it doesn't fit over the board. The screw holes in the metal plates don't line up because of the upper left ziff socket.


    As for now I am leaving the metal plate off.


    First question:

    Do I need to arrange some separate cooling solutions for the chips or is the passive cooling enough?


    Everything seems to be working.

    Except the screen is monochrome. I have tried a different VIC chip (6569) as well.


    The C64 is hooked up via S-video to the S-video port of the TV.

    The TV port itself is configured to PAL


    Unfortunately all my old C64's came with an Antenna connection instead of the Video DIN one. So I don't have any cables lying around to test it.


    Second Question:

    Is there something I can try to get the colors back? Perhaps some setting I overlooked somewhere?
    I'll be buying a new S-video to tulip connector cable when the stores are open again.
