I thought Vic20 JiffyDos was already being sold a year or two ago?
It was produced and sold by Maurice Randall at one time, but is no longer available. Retro Innovation currently holds a JiffyDOS license from CMD, but it does not include Maurice Randall overlay for the Vic20.
Here is what Jim Brain had to say on the subject:
* JiffyDOS for VIC-20
* JiffyDOS for +4/C16/C116: While there are ports floating around,
they are mired with uncertain copyrights, and I cannot legally
obtain all the clearances. I've been instructed by Mark Fellows
to just re-port them. THe VIC-20 one is easy, but time is short
around here. The +4 one will require more work.
