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)

That's a really great idea, but I'm thinking all the external hardware 
to control that pseudo-floppy is expensive. Wouldn't it be cool if the 
CPU core had an alternate register set and memory space? Like a 
user/supervisor mode- you hit a hotkey and the normal processing is 
suspended, you get an on-screen menu to mount/unmount floppy images with 
names and descriptions (instead of a number on an LED display) then you 
can just resume normal operation. Kind of like how MESS works. It would 
probably be less costly from a hardware perspective I would assume.
