Controler
This model was introduced for use with the CoCo 2 (as it lacked the original CoCo's +12V power supply), and is also mounted in a long cartridge. Early 26-3029 controllers had a Fujitsu MB8877A (5-volt only equivalent of the WD1793) and are capable of high density 3.5" drive operation. Mike Pepe has a page showing how he upgraded a 26-3029 controller: [1]
Note that most 26-3029 controlles use the WD1773 floppy drive controller chip which IS NOT capable of operating high density floppy drives.
Drive
26-3029 'Color Computer Mini Disk' This drive model had a white case, but was still a full-height, vertically-mounted assembly. These first two styles have 34-pin card-edge connectors on their rear panels rather than captive ribbon cables. The addition of extra drives required using additional case/power supply/drive units.
