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!
(If your chip is soldered to the motherboard you will need to unsolder it and install a socket)
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, also on sale elsewhere.
22€ (8$ royalty fees included) + eventual Paypal fees + shipping cost
