(Please, notice, I havn't talked about Colour TV)

First, basicly 70's tv had the same specs than todays.
And second 64 colume _and_ in colour _and_ NTSC ?
Say, do you still belive in the child, bringing all
the gifts ? (Or in Santa, to mention the US variant ?)

For NTSC is even 40 Columes hard to display, since a
yellow to blue change and back (for example, to take
a often used foreground/background) can be done 160
times within one scan line - but nothing else - you
will just get a kind of glowing screen. But thats not
a problem of using a TV set, thats a problem of the
NTSC colour signaling.

And if we talk about a 1976 design of a text screen,
the natural CRT would be a B&W set - still around
this time, the majority of all sold TV sets have
been B&W.


Ich denke, also bin ich, also gut
