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.

the 26-3022 Mini-Disk System was the first production release of a disk controller/drive for the Color Computer.
The controller is based on the WD1793. It features an analog data seperator section, and has multiple potentiometers which are used to calibrate various delay and timing features of the disk-side interface. It requires a 12 volt supply to operate, and is thus not compatible with a CoCo 2 or 3 unless a Multi-Pak Interface is used or the CoCo or controller are "hacked"
The disk drive is a Texas Peripherals unit encased in a silver-colored enclosure with a simple linear power supply. The drive is capable of accessing about 37 tracks, so a 35 track limit was imposed in Disk BASIC.
These drives are not the most robust, and many that are out there are probably in need of work. (if they work at all)
The 26-3022 controller is relatively easily modified to support high-density disk drives.
