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 (www.arduino.cc), 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. Yours ATT ---------------------------------- Ein Service von http://www.news.at Message was sent through the cbm-hackers mailing list
