The Catweasel is an add-on card for the PC which allows reading TRS-80 floppy disks. It works by emulating a floppy disk controller using a combination of hardware and software. At the very start of the current project I believed that similar functionality would be possible by reversing the input and output signals and connecting a TRS-80 floppy drive to the interface board. Just recently I have succeeded in doing this.
The interface board plugs into the top of the Raspberry Pi and the floppy card edge connector plugs into the TRS-80 floppy disk drive. The logic analyzer plug is for testing and development only and is not required for operation.
The interface board sits on top of the Pi during use. It is about the same size as the Raspberry Pi. No PC or Mac is required as this is a complete standalone computer system…
