Switchless Kernal selector PCB. Provided with original Kernal & JiffyDOS (official licence worht 8$ included!).
In basic use it replaces the original Kernal. Second Kernal is started by keeping down the Restore-key while turning on the machine. The default Kernal can be selected with a solder bridge or jumper.
This PCB can also replace the BASIC ROM on the motherboard (anyROM feature). The PCB can be in the BASIC or KERNAL socket and replace one or both ROMs.

Re: Switchless JiffyDOS for VIC-20 + BASIC ROM replacement
I changed the PCB to the V2 model. Jumper 1 is for PAL/NTSC. Jumper 2 is for selecting default kernal between original & JiffyDOS.
Picture shows standard installation and two options for replacing both Kernal & BASIC ROMs.
