- Hey, that sounds a *lot* like what I used to do on my Tandy Color Computer 3!!!
- Just had to use a simple BASIC "poke" command into a certain location on the

- it down in order to write to the floppy (but not for reading), but the
- point is the speed-up worked! Ran the multi-tasking OS/9 operating system
- pretty darn quick in that "sped-up" mode. It performed rather well for
- a 1/"2" MHz machine.
