[Coco] CoCo Model 1 Cartridge Port

I may be wrong here, but my understanding is that you need to update the ROMs in the actual computer to get DECB 1.1. The Disk Controller ROM just "expands" by adding a handful of commands.

On to the cartridge port, which seems workable.

Verified that the Deluxe RS-232 Program Pak (Cat. 26-2226) can be invoked with "Exec &HC000"; I/O TBD.  Got modems and cables, need to find / create a driver.

Also verified same for Disk Controller (Cat. 26-3022) which boots up with the message "Disk Extended Color Basic 1.0".  I have the disk cable, a drive and blank disks but no software.  End-to-end communication yet unproven.

I think there are later ROM versions used with (some version of) the disk controller; can they be used in this cart?
