[Coco] Making my 80T 2S OS-9 Boot Disks boot able

[Stephen Fischer]

I just realized that the floppy controller in SHF15 was for the DISTO 
No-Halt and that may be why it may not boot.

I keep thinking that the offset to the boot track is messed up by the 
conversion to a .dsk is the problem. That's why I asked the question for 
using DED. Double sided disk to single sided .dsk.

So I must either find what I did for the original Jeff Vavasour's CoCo 3 
emulator, Or try another disk. Someone wants to stay far far away from 
NitrOS-9 Level-I due to the decreased memory available.

So it's OS-9 Level-I that needs to be booted in VCC, I just thought it 
was better to go with my last system which I want to get running anyway.

Perhaps SHF13 OS-9 L-I V02.00.00 which may use SDISK.

It has been so many decades since I tried to get my old system running.

I live ~ .25 mile from Murphy's house so he has many chances to mess up 
what I want to do.

NitrOS-9, the last time I tried to download it I got 100GB in addition 
to the OS with every book, help file and so on ever written for the 
CoCo. I stopped that install just in time and went back to the last 
restore point.

Now it's Hyper-V and Vista for CoCo stuff so my W10 laptop will not get 
messed up. But that is an animal that I have yet to tame. The Virtual 
Machines I used before were easy compared to Hyper-V.

BTY, The computers with floppy disk are down to two and one is my 
Weather Station and the other is about to get a new MB due to problems 
with the old one. It must be in good shape to be a backup HTPC.
