2025-12-29: I have restored the wiki to a backup from the end of November. Starting in September 2025, accesses went form the 800MB-1.2GB range per month to 26GB in September, 42GB in October, and 70GB in November with most accesses originating from China. As soon as I realized what was causing all the access problems in November, I shut it down (it had reached 36GB by then) behind a password/login screen. The database had gotten corrupted, and I tried a restore from just before the spike in access but that didn't work. Thus, end of November. I still have the other daily backups so if there were any important additions in December, let me know and maybe they can be recovered. - Allen H.

Controller
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 controllers 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.
Owners of the 64K CoCo 1 (26-3003B) faced the problem of their computers not visually matching this disk drive's original TRS-80 silver or "battleship gray" color scheme. According to the December 1984 issue of The Rainbow, Radio Shack advised [2] that these owners instead get the External Drive 3 for the Model 4 (26-1161). While this would solve the problem of the case color matching, it created a new and different problem of the case badge no longer having the word "Color" nor the red, green, and blue rectangles.
