AAAH, so you do NOT really need JiffyDOS EPROM into the machine! This is great news!
(anyhow, the Plus/4 PAL Jiffy was very hard to find)
Much easier to get a JiffyDOS ROM ready 1541 or 1571 drive. And use this fantastic piece of SW. Many thanks, BSZ!
Thanks for the tip too, I was not aware, or forgot it!
(too bad C= team was not that smart, and made the 1541 even slower than 1540. Imagine the better image of Commodore 8bit machines if they would be as fast as with Jiffy out of the factory, lighting fast program loading speeds).
One question remains: how it could be, that with JiffyDOS the loading becomes 10x faster on the serial IEC, while 1551 with the parallel bits it is still only 4.5x faster than the original 1541? The 1551 used it's own routines, why C= kept the slow bit-handling routines? With the much more data lines and direct memory access the 1551 should be ~20x faster with such fast routines, right?
