NOTE: If you select JiffyDOS, you’ll need to be sure you have an official JiffyDOS license. Licenses can be purchased from Retro Innovations for $8.00.
This ROM replacement for the Commodore 64 will give you the ability of utilizing the RESTORE button to switch between ROMs. The most common configuration is to have the original Kernal ROM and JiffyDOS to swap between but there are other Kernals that could be utilized instead. If you need other Kernals then please let me know when you check out.
To function, you’ll only need to make sure that you’ve got your board prepared by having a socket for your Basic / Kernal ROM and then solder 2 wires to the board and then to the replacement Kernal ROM.
You can also choose not to solder the wires and just use the ROM as a drop in replacement to replace your existing Kernal
