It'll do something if the Term board/video board functions :) That's why I
suggested first seeing if the video section and Terminal on "Local" works.

That's exactly my point Tony. Nonetheless, regardless of the label used,
you're more of a wellspring of technological documentation -at least
regarding computers- than I've ever experienced.

I try to latch onto any technical docs that I can that is related to any
kind of electronic device. I've often been pleasantly surprised when I
either got for myself or had to fix for someone an early radio or somesuch :)

"More info" . . . yes indeed, that's the influence of the good old Heath
Company in writing those manuals :) In my mind, and other Heathkit
collectors' minds, they set the standard in how a tech manual should be
written and presented.
