Hi Ruud!, > Please see the bottom of http://www.jschoenfeld.com/products/catweasel_e.htm No, I mean some simpler hardware. As I see the Catweasel must be kind of a bitstream capturing device (ie. it is a standard ISA card that probably captures / writes one whole track to / from its onboard RAM, that your PC program can reach through I/O ports). Instead that - let's suppose a small microcontroller based board on the floppy cable itself. It could be a 'through' interface, ie. you connect the floppy drive to its one end and connect the interface to the PC floppy controller with the other. The uC would be programmed not to interfere with any regular floppy operation - but if it received a special MFM sequence, it hooked the floppy controller signals for itself. The idea is to leave all usual tasks to the PC (select head, track, turn on the motor etc.), and instead of buffering, rather let the microcontroller generate a 'fake', long MFM sector (containing one full track), on the fly, from the raw bitstream it is receiving from the drive. I guess it could work similarly into the other direction. ...Provided that the main idea is correct. I had this idea since a long time, I just haven't known such vital infos that I just read in the article... (and also, I probably still couldn't write the neccessary PC code myself). (Heh... If it worked... Imagine reading a full 1541 disk in hmmm... 35* (60/360 + 0.05) = 7.58 sec ;-) in a regular 5.25 HD drive... (and I was probably too pessimistic about the floppy seektime).
