Since ISA Catweasel was announced, a Freeware project has appeared on the Internet, using a handful of cheap chips to connect an Amiga drive to the PC parallel port. The card is synchronised by a 28.322MHz crystal oscillator in the same way as genuine. A socketed MACH211 gate array provides the bulk of the interface logic, augmented by ten smaller logic chips. The biggest chip on the board is the track buffer, with the stripy tail Catweasel logo. It worked first time on our test machine, a well-stuffed 200MHz Pentium. The default, marked on the board, is $ 320, but you must change this by moving jumpers if other boards on your system already use that space. A ) A Four jumpers on the card set its port address. ) ( ) ISA Catweasel may appeal t hackers, but without more software it's a feeble solution to PC disk limitations. ![]() This is twice as fast as O genuine Amiga drives but is limited by the double-density7 transfer rate of Commodore’s Paula chip. Amiga 3000, 4000 or one of the add-on high density drives for other. For good measure, Catweasel also gives access to 1,760K media, formatted on an. ![]() On the face of it, the ISA Catweasel could cure the biggest weakness of UAE: its reliance on a real. ![]() We’ve been waiting for a review copy of the ISA version of Catweasel, which plugs into a PC expansion slot, since we planned our review of UAE and Amiga Forever. It plugs into an ISA slot, but not on your Amiga. The name comes from a cartoon TV series and the logo from the back end of a lemur. Amiga version has been much more successful, giving fast access to many disk formats, using cheap drives rather than special Amiga variants. The Catweasel floppy disk controller from Jens Schoenfeld was designed to allow PC systems to access Amiga floppy disks. ![]()
