[Coco] Need utility to read Flex-09 floppies.

[Stephen H. Fischer]

Hi,

It may not be of help, but I have the Flex "Adaptation Guide" manual for
"Unknown" computers.

I.E. You build a floppy disk controller and then write the bootstrap code
using an example in the manual. A short and very simple boot loader used
only to get started.

Not a easy way to do it when you have just purchased two miss - aligned disk
drives.

Worked much better after dealer replaced the drives.

And on a SYM-1 if you believe it. I have perhaps the only upgrade for the
SYM-1 from the 6502 CPU to the 6809 CPU (Satellite board required).

Then the display and keyboard have to be built and the software written.
(Display was a SYM-(Perhaps 2) and hand wired keyboard)

I never really did anything until I got my first CoCo.
