[Coco] emulator problem

[John Donaldson]

I''l try one better, I'll make a new 80T boot disk using DSKINI.exe and 
use RETRIEVE.exe to
remake it into a  DSK. Then I'll change DD.DMT byte so that the emulator 
will see it as a 80T
DS drive and see if that boots. I already booting from a 80T DS DSK drive.

    I understand that IBM did some changes to the floppies on the 
thinkpad laptops, but this is
a old 486 DX2 desktop and it uses the standard floppy cable. BTW, this 
is about the oldest
system I have seen that has both a PS/2 keyboard and mouse connectors.
