Mine are for specific-purpose applications, so they're not likely to be of use to anyone else. Note that I'm not interested in archiving disks, but rather getting at their content and saving that. But golly, it isn't that difficult--most MCUs have several timers, and a "capture" facility so reading should be easy. Writing is again, mostly feeding a PWM output to the drive. The floppy interface itself is very much brain-dead.

This isn't news--the HxC emulator basically does the work and runs on an STM32F1 platform--which is weak tea compared to the ARM CPUs currently available.

My .02 cents. Chuck
