    Default Commodore 64C (shortboard) : JiffyDOS "wireless"!

    Now I'm proposing a C64C (shortboard 250469 motherboard) JiffyDOS with "wireless" solution:
    it will be sufficient to plug it at the place of 251913-01 kernal+basic ROM on a socket
    and it will work without piercing the case and WITHOUT EXTRA WIRES!

    How to handle switching between kernals?
    The C64C will boot-up with standard kernal (I prefer always that on standard boot-up the machine seem not modified....)
    and for swapping the kernal a RESET has to be performed, Hardware or Software!

    Hardware: lowering the /RES line (example: pressing the RESET button on an external card...)
    Software: typing "SYS64738"(+"RETURN").

    NOTE: the price includes the $ 8 that will be paid as a copyright at the conclusion of the sale.

    This mod will be assembled on request.
    22€ (8$ royalty fees included) + eventual Paypal fees + shipping cost

    to be clear ,this is for the actual jiffydos plus basic switchless board right?, most short boards dont come with a socket

    or..is this with the c64 shortboard as well?,its not entire clear
    i have got too much hardware,it would only hurt your eyes to look at it here

    It replace the kernal+basic ROM 251913-01 used on 250469 motherboard (the one that has the big 64 pin PLA),
    I know that normally it's without socket, but if you want to plug any kind of new kernal a socket has to be used, after this the modify can be plugghed/unplugghed without soldering any wires and without makhing holes.
