Coco FDC on a Dragon computer

[jltursan]

Please note the Dragon firmware is NOT from Dragon Data, it is a modified version to allow the DOS to work on the CoCo's different FDC controller.

Thanks for clarifying this, that makes more sense to me. So it must implement the HALT/FIRQ conversion...

Indeed is nice to see it working thanks to Ian's post

Hi everyone, video shows the DragonDOS-only FDC running on my Tano 64:

And this video shows the other FDC I did last night with the switchable RS-DOS 1.1 and DragonDOS:

It was a pleasure sharing it with you Ian, thanks for the acknowledgement.

Thanks Bas, and everyone else, I've needed a kick up the ass to get onto this project which has been in the back of my mind for years.

Don't you mean a SPDT switch?

I'm going to try this. I ordered the switch and resistors. Gotta track down my full sized cartridge.
