TRS 80 Model III Exatron Stringy Floppy Boot Wafer Copy Program
This photo is a continuation of the boot process. AS you can see menu selection 1 was used to activate the program to copy of the boot wafer. This is important because if you have no boot wafer the Model III version of the stringy floppy system is useless. I accidentally inserted a 6' wafer so I decided to @new (format) the wafer instead. So far I have not been able to make an working copy of the boot wafer. I don't want to erase wafers that have programs on them.

Cassette cable ports on the back of Model III Exatron Stringy Floppy
On the rear of the Model III version, you find ports for a standard 3-wire cassette cable, as if the wafer drive were a cassette player. The other end attaches to the cassette port of the TRS 80 Model III. Click image for larger view.
