Exatron Stringy Floppyby billdeg Total messages in this thread: 2 Updated: [ Exatron Stringy Floppy ] 05/23/2005 Here is a preview of a more in-depth report on the Exatron Stringy Floppy Pictures 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. Bill D">... [ read more ] |
