Options for USB on A2000...

[Matt_H]

Your options are:

Thylacine
Highway
Algor (Pro)
another Zorro board w/ clockport + Subway

You'll need some other expansion as well. 030, Kickstart 3.1, some RAM. There's a new USB stack on Aminet that can run on basically unexpanded 1.3 systems, but it doesn't yet support massstorage devices.

The Thylacine is pretty cheap. Check out this thread from a few weeks ago. Registering Poseidon will cost more, but you may be able to get by with the included Sirion stack.
