The controller/computer probably can't handle the higher data rate of the HD
format (twice the DD rate).

You should use LaddieAlpha. I built it. That's the right place. It's safe.
I don't know anything about Win7 Smart Screen. I assume it alerts for any
executable program.

Group,
I purchased a REX at Tandy Assembly 2018, but am just now getting around
to testing it with my T102 Dual ROM/128KB RAM Memory System.
The REX Wiki instructions tell of needing a TPDD PC emulator (I have no
TPDD device) but it does not indicate what program to use, or where to
download
interestingly,
Yes, if I take an HD disk, and tape over the hole to make it appear to be a
DD disk, then it works.
But why?
the floppy is capable of both formats...

the Coco is using it's standard controller
the Coco is using it's standard controller
When issuing the DSKINI 0 command the coco tries to format for 180kB.
The combination of
(Coco, std controller, PC 1.44MB drive + a 720kB dd floppy) works
whereas
(Coco, std controller, PC 1.44MB drive + a 1.44MBB hd floppy) does not work
this is
likely the floppy controller doesn't support 80 tracks or high density..
most of the controllers of the era are ds/sd 40 track or dsdd 40 track..
are you able to format 720k? ds/dd 80 track?

I'll start by saying this isn't an M100 or TPDD discussion, but just
looking to understand something.
I have a Tandy Coco3 with a 3.5 inch floppy drive. The drive is a standard
PC drive and it is working well.
Seems though that I cannot use 1.44 MB floppies in that drive. They don't
seem to
