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.

Home / CoCo Relatives - MM1
Note: the actual product name was not MM1 but MM/1 with a slash, but the nature of URLs and wikis prevent the correct "MM/1" from being this article's title.

The MM/1 (Multi-Media One) was an attempt to make a CoCo-inspired OS-9 machine. It ran OS-9/68000 and included the K-Windows windowing system by Kevin Darling which supported the CoCo 3 style windowing system. The hardware was based on Philips chips used in the CD-i systems.
The machine was initially sold by Interactive Media Systems, then later taken over and sold by David Graham of Blackhawk Systems in Oklahoma.
Unfortunately the platform did not catch on. CoCo users who had never bothered with OS-9 had no compelling reason to adopt it. Some CoCo users felt loyalty to Tandy and thus migrated to Tandy's MS-DOS/PC machines, especially the Tandy 1000 series that offered CoCo-compatible joystick/mouse ports and which could use some other CoCo compatible accessories such as the Koala trackpad and some of the Tandy printers, modems, and external hard drives.
Probably no more than 500 MM/1's were sold[1] and the company that built it folded shortly after. There has not been an attempt to make a next CoCo since then until the recent CoCo-X project by Gary Becker was announced.
Sub-Etha Software published several MM/1 programs.
