Versions [edit]
Mk1 and Mk2 [edit]
The initial version of the Catweasel was introduced c. 1996 and has since undergone several revisions. The Catweasel Mk1 for the PC ISA bus and Catweasel Mk2, for the Commodore Amiga 1200 and Amiga 4000, sold out in October 2001. The Mk3 added PCI compatibility and sold out in mid-2004. It was succeeded by the Mk4.

Official software and drivers are available for Windows, [3] [4] and unofficial drivers and utilities are available for Linux. [5]

Mk3 [edit]
The Catweasel Mk3 was designed to interface with either a PCI slot, an Amiga Zorro II slot or the clock port of an Amiga 1200. In addition to the low-level access granted to floppy drives, it has a socket for a Commodore 64 SID sound chip, a port for an Amiga 2000 keyboard, and two 9-pin digital joysticks (Atari 2600 de facto standard). [6]

Mk4 and Mk4plus [edit]
The Catweasel Mk4 was officially announced on 18 July 2004, with a wide array of new features planned. However, due to manufacturing delays and production backlogs, the Mk4 was not released until early February 2005.

This version of the Catweasel makes heavy use of reconfigurable logic in the form of an Altera ACEX EP1K30TC144-3N [7] FPGA chip, as well as an AMD MACH110 PLD and a PCI interface IC. The Mk4/Mk4+ driver uploads the FPGA microcode on start, which makes easy updates possible without having to replace hardware.

The Catweasel Mk4Plus appears to be no longer available. [8]
