I think you're far more likely to blow the CM-8 with a higher horz freq!
Better get/borrow a multisync monitor.

My thought is: it'd be a better idea to grab some old, cheap CoCo's
and create EPROM paks for them which contain code to do much of the
handling of the serial login ports... and then have them send data
to/from the main CC3 via say, the old keyboard parallel port or ??

That should work much better than attempting to overspeed the coco board.
Plus it might make a neat commercial product ;-)
