The necessary delay between doing an erase and

to draw again (a second or two), or the bright blink when you erase?
You can only erase the entire screen?
Overwrite doesn't replace a character, but actually just draws
over it leaving the old character behind?
Lack of scrolling ability?
I wouldn't characterize these as bugs - they are in the nature of the
storage scope technology.
Using that reasoning, you could say that raster graphics has the "bug"
that lines are aliased.
Funny things happen if you send graphics coordinates
too fast
(making the "short mode addressing" useless at high speeds?)
Now this starts sounding more like a bug. What "funny things" happen?
Didn't it also use RC networks for the serial
clock, and there
was a pot to tweak? That was the thing that struck me as being
really chintzy at the time, but there was that pot for rubbering
the frequency...
This doesn't sound like a "plotting bug" either, just something you
didn't like :-)
GIN mode? (And the other GIN mode?) And the funny
characters that
could come out that some minicomputer OS's just did not get along with?
Can you elaborate on this? IIRC, GIN mode is where you used the
crosshairs to indicate x,y position and then pressed RETURN or
something to send the position back up the serial line, right? What
do you mean by "the other GIN mode"?
Of course, to you and me these are just intrinsic
characteristics
of a 4010, but to someone who grew up with non-storage-scope
CRT's they probably could be frustrating.
Well, this quote was taken from a page showcasing a vintage computer
collection, so its not like the guy is unfamiliar with old tech.
