    Default ROM VIC20-C64-1541-(SX64) Test & fix ROM-sets: 8xMultiROM!

    The 8xMultiROM is a settable ROM: the perfect tool for check & replace a ROM-failure into your VIC20, C64, 1541, (SX64).

    The 8xMultiROM contain the image of:
    -C64 KERNAL 901227-03
    -C64 BASIC 901226-01
    -C64 FONT 901225-01
    -"L" 1541 325302-01
    -VIC KERNAL 901486-07 (PAL)
    -VIC KERNAL 901486-06 (NTSC)
    -VIC BASIC 901486-01
    -"H" 1541 901229-05


    For the VIC20 character (font) ROM a specific solution is needed,
    SX64 KERNAL can be tested with C64 KERNAL but it has to be replaced with a specific ROM not included (ask me for it)

    8 MultiROM is available in two different option: the 'Tester' and the 'Replacer'.
    The Replacer is intended to stably replace a ROM, it's image is selectable by soldering 3 pads on rear (on request I can set it for you).
    The Tester is intended as tool for troubleshooting, the ROM binary image can be easy selected with DIP-SWITCH for an easy ROM-check.

    This ROMs need a lot less power than originals, this will lowering the internal computer temperature and also of the PSU...

    This circuits will assembled on request:
    5€/PCs 8xMultiROM (Replacer)
    5€/PCs Font ROM for VIC20
    15€/PCs Tester-8xMultiROM
    Minimum order: 10€+ shipping + PPfees

    For other ROM please look:http://www.amibay.com/showthread.php...-EPROM-27HC641

    Apologies for the newbie question, I need for my VIC 20, the basic ROM, i.e. 901486-01 and I like also, the Tester ROM for troubleshooting. Both of them are drop in replacements, and have 24 pins like my faulty one ?

    All "8xMultiROM" have 24 pin to be plugged directly on the socket of the original ROM that is intended to replace.
    If you want an already selected image on a "replacer", remeber to ask me for it: I'll select it for you before shipping.
