JiffyDOS requires a ROM in the computer as well as the disk drive. If you have a switch on the JiffyDOS drive ROM then you would remove the switch and connect the green wire to ROM select line. That is the line NOT connected to ground.
Right now I'm mostly using the Ultimate1541 which is Jiffy:ed but eventually, now that I've removed the old DolphinDOS installation I'll add JiffyDOS to the FDD board. As for the "ROM select line" I'm told this is A13 (pin 26) on a 27c128. Correct?
I believe this could be clarified in the otherwise brilliant installation guide
