Dear Ruud and the rest, 

I'm sorry for being so off-topic, and I appreciate the large amount of hard 
work you put into the 1541-IDE-project, but I wonder if it wouldn't be wiser to 
try to make a sort of 8-sec-copy / nibbler hardware/interface for the 1541 so 
you can transfer the disks fast from 1541 to PC and vice versa.
All we need is a little AVR, most likely in the arduino style (, 
a parallel cable on the 1541's side, the usual serial cable, perhaps a bit of 
RAM and a transfer via USB from and to the PC.
This would keep 1541 hardware modification to a minimum.
The AVR ought to behave like a c64 for the diskdrive, including the timing 
critical handling of the fast parallel port routines such as being used in 8 
sec copy, burst nibbler, etc. Granted, it will be hard to get it to work 
because it has to be cycle-exact, but it is far from being impossible. Ruud 
would be the ideal hardware-man for this, and if we take the routines outta 8-
sec-copy or similar, we simply do not have to twiddle with software development 
too long.
What do you guys think? Let me know.
