Hmm, I bought an early Catweasel for my A1200 tower to give me some extra drives, but never got it to work :-(
Its been a few years since I took the old tower to pieces, but I seem to remember it needed the clock port, and my mobo didn't have the headers, so I soldered my own in. Unfortunately I could not get it to work at all :-(
Ended up with an LS-120 instead on the 4 way IDE adapter which could do both HD/DD and 120Mb discs.
Maybe I still have the Catweasel - anyone interested ? May not be complete but could be useful to someone ! (As long as I didn't fry it with my home made header).
