[Coco] Sierra Xmas 86 demo

[Stephen H. Fischer]

Hi,

What should DNS be for my 80 Track 2 sided 5.25" Disks?

If you look at the definition for 3.5" disks, the DNS should be DNS = 3.

 I had A 80T2S 3.5" drive and a 5.25" 80T2S which I swapped /D0 and /D1 with 
a switch.

But most people having only 3.5" 80T2S drives might well have DNS =1.

What a mess Charlie Brown. Your rule "It should dns=3 for 3.5 and dns=1 for 
5.25" just does not work.
