I'm assuming that after you fire up the emulator you have have to boot OS-9. But that's reasonable! Is there a way to get a 5.25" floppy drive attached? I'm assuming that for now you just use DSK files and the 3.5" floppy, thumb drive, or CD to get CoCo files on the laptop. Hmm.. forgot it's a 486 laptop, might not have a USB port!

Has anyone ever looked at one of the 3.5" USB drives? Is it a circuit attached to a standard laptop floppy? If so, I wonder what it would take to attach it to a 5.25" drive? Should just be an adapter for the connector...

Frank,
  I am doing this with a OLD 486DX IBM laptop. It runs DOS 6.2 and has 
both the
JVC 6809 and the JC 6309 emulators, both running NitrOS9. When it boots 
autoexec.bat
runs a simle menu script that allows me to select either a 6809 or 6309. 
Then the select
script fires up the emulator. When I exit the emulator it calls the menu 
script again.

considering is tkaing the old P166 laptop I have and configuring it to auto boot 
into the CoCo3 emulator. If the emulator can be patchd or configured to 
automatically open in a specific setup (like max memory, number of drives, 
etc.), then I'd have a virtual CoCo4 ready to go. The next step would be to have 
the emulator not only auto start, but load NitrOS9 automatically. Can that be 
done with a DOS script? My thinking is to strip down DOS to a minimum to reduce 
emulator overhead. Anyone see any problems with this? Will the P166 laptop 
(remember, a laptop generally runs a bit fater than a desktop due to better 
integration -- "seat of the pants" feel on this one is like a P233 or so 
desktop) be fast enough to seem at least like 4-5 MHz CoCo, or at worse a 
standard CoCo3 at 2MHz? Any problems with the LCD screen?
