Hi all,

Motivated by CoCoFEST and Steve's emulator videos I went ahead and installed VCC 2.01 with Drivewire 4 (using DECB). All went well and I am documenting what I have done; however, I have a question. When setting up the Becker port I need to select an external ROM within the FD-502 floppy controller configuration.

When looking at the files included with VCC I see four similar ROM files for HDBDW:



hdbdw3bck w-offset 5A000.rom

hdbdw3bc3 w-offset 5A000.rom

>From the documentation that I found, it seems that those with the 5A000 offset are for use with NitrOS9 and those without it are for DECB. Further, those ending with bck are for the COCO 1 and 2 while those ending with b3 are for the CoCo 3. Is this correct? Thanks all! Salvador
