JiffyDOS, down to low level, is NOT a hardware solution, it is a replacement communication protocol for the IEC port that is SOLD as a ROM replacement for your drive and computer.nbla000 wrote:JiffyDOS is an hardware solution, i don't like to modify Vic-20 and drives, my best choice is a cartridge and/or a loader as first file of a 1541/1581 diskeslapion wrote:JiffyDOS ?
However, in reality it is a piece of software that resides at addresses normally used by your kernal. But in fact, there is nothing to prevent you from putting it at different adress ranges.
A real hardware solution is something like the parallel cable between the user port and internal 6522 unused port.
The beauty of jiffyDOS, on top of that is since it doesn't need to reprogram your external device, you could, in theory implement it in drives that don't even have a 6502 or compatible processor. You could implement it in an atmel or PIC processor that acts as a hard drive or other storage devices controller.
