Tim's own version of the Catweasel/Compaticard/whatever

From: mann(a)pa.dec.com (Tim Mann) It's definitely possible to pull the crystal oscillator on a Catweasel and substitute another frequency. Jens (the designer) sent me an email mentioning that he'd put a 40 MHz clock in one for a test he was doing -- he connected it directly to the output of an Amiga's floppy disk controller in order to find out for sure where the FDC was applying write precomp. I don't know when or if I'll get around to trying to change the crystal myself, but I'll definitely let you know if I do. I might also forward some of the mail we've been exchanging to Jens and see if that makes him think about supplying a different crystal as standard. It would seem that something with a factor of 3 in it would be best, since the 300 kHz data rate used for 5" double density in a 360 RPM drive should be accommodated too.
