2024-03-02: The wiki ran out of disk space, so things were not working. This has been resolved by adding another 5GB of quota ;-) Thanks to Tim Lindner for reporting the issues. 2020-05-17: If a page gives you an error about some revision not being found, just EDIT the page and the old page should appear in the editor. If it does, just SAVE that and the page should be restored. OS-9 Al (talk) 12:22, 17 May 2020 (CDT)

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.
