[Coco] FHL Color Flex

[Stephen H. Fischer]

Hi,

Bob, my bad, and I had the manual right in my hand a second before. Print 
too small for my new eyes.

Darren, OS-9 disks have the density in the .dsk file, but the utilities do 
not use it AFAIK.

I have been trying to determine if Track 0 single-density has a different 
number of sectors, so far TSC in their FLEX manuals says 10 and 10 for the 
double-density tracks.

FLEX is the only OS to do this different track 0 AFAIK.

If that is true, then a .dsk would not be any different if all tracks were 
double-density including track 0.

But then why are we having problems with "188AA_02.DSK"?

Luis, can you extract: "DRIVE is 0, TRACK is 16, and sector is 9"?

A hex dump cannot be disassembled but someone with experience might be able 
to read the hex and understand it.

I could do that ~ 1970 for Super Computer PP code.
