Hi, I'm checking the feasibility of using the Teensy as an ATAPI ZIP Drive Emulator.
The basic hardware flow would be as follows:
The basic software flow would be as follows:
Power Supply: I plan to use the 5V supply, which was originally there for the ZIP, to power the Teensy. I assume that a power supply originally designed to power bulky hardware, with at least one motor in it, should be able to power this Teensy rig no-problem.
Processing Power: The Arduino would seem to struggle with this task, which is what led me to Teensy. It looks like ZIP maxed-out at a 1.4 megabyte/second transfer rate so I think I should be safe there...

Am I on the right track? Seem feasible? Any pointers on existing code that could be modified would be a huge help!
Thanks for any thoughts!

[USB Drive (emulating the ZIP Drive's storage)]
The basic software flow would be as follows:

[USB Storage Driver (off-the-shelf/existing?)]
