Sitenotice: 11/29/2018: The wiki is back. It turns out, some anti-virus product on my web server had an issue with the latest version of PHP. My server techs have resolved this issue, and things should be working again. During the investigation, I did restore to a backup from September. There is a chance that any changes done since then were lost, but I do not recall any edits. --OS-9 Al

8/30/2016: Massive re-work is being done on the InfoBox Templates. Read that page to keep up with the plan for that, and adding better keyword tags (categories) to all the pages. --OS-9 Al (talk) 15:28, 31 August 2016 (CDT)

About the Info Box

The MM1 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.

Sadly the industry had changed too much and the technology was sort of dated and the PC and Macs were just beginning to reign supreme as well...

Not more than 8 units were sold 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.
