[Coco] Dual monitors on a Coco 3?

[L. Curtis Boyle]

We had The Eliminator card from Frank Hogg labs (which had 2 6552 based serial ports - much better chip than the 6551 - as well as having a printer port, auto-boot ROM, real time clock, and no-halt floppy & hard drive controller), a Comm-4 Board from Alpha Software (4 6551 based ports), and Bill Nobel made a custom card with 2 more 6552 based ports.

Full multi-user and multi-tasking. There are some text editors and terminal programs that supported TERMCAP style capabilities,so we could run them on various kinds of terminals. We even had a custom OS9TERM program for DOS that supported OS-9 display codes for colors, changing screen resolutions (Text only), and even supported overlay windows.
