The stingy floppy was introduced in April 1979 at the Computer Faire in San Francisco USA.
The order form for the purchase of a stringy floppy includes a field to select the drive software for either the TRS 80, SWTP or S-100. I have a typed copy of the s-100 assembler, but it's for the Cromeco.
The "nose" protrudes 1/2 inch from the drive. The dimensions of the hole from which the nose protrudes is 3" wide x 1" tall
The Stringy Floppy Wafers are 2 11/16" x 1 9/16" (must be metric).
Most of the documentation refers to the TRS 80 with Level II BASIC, except for the Cromeco assembler.
