I give up. I can't figure out how you define "monitor".
Nor can I.
It's clear (I hope) that the thing I use on my workbench with a
raster-scanned CRT and a composite video input is a 'monitor' by any
normal defintiion. It's equally clear to me that the DEC VT100 is not a
monitor, it's a terminal (although it contains a monitor).
But there are plenty of grey areas between them.
Is it a raster-scan CRT? If so, then yes, it doesn't directly do characters.
Is it a vector-only CRT? If so, then again it doesn't directly do characters.
Try as I will, I can't think of a _CRT_ that can only be raster scanned
or vector scanned.
Is it a vacuum tube with a phosphor face intended as
an output device viewed by humans? That would be the definition I would assume you're
using. If so, then the SAGE displays fit: those are direct view tubes that can display
both vectors and characte
rs, and the character display is a Charactron.
Esactly.
