You are both right: the Viking Moniterm was a Sun-style 19" mono monitor
and a card for the video slot, and the A2024 was a monitor with a 23-pin
Amiga video connection and all the necessary goodies inside. I had an
A2024 once, I still have the Moniterm.
Both use the same driver and the same techique - squeeze out four fields
from the Amiga chipset and externally buffer them into one frame that is
put up as a 1008x1008 2-bit greyscale image. As long as you didn't try
to scroll text across the quarters of the screen, it worked nicely, even
for Macintosh emulation. There was a bit of judder if you tried to use
a text window across that split. The bits didn't flicker, but the left
and right sides would refresh at a visible difference.
The A2024 will work with any Amiga. The Moniterm will work with any
Amiga that has a video slot (although I never tried it with my A1000
and Rejuvinator ;-)
Great stuff if all you wanted was lots of desktop realestate. I used mine
while developing text apps - lots of room to edit, compile and test. I
even created a flyspeck font (1x2) to run my makes in a 1000-pixel-tall
window on the edge of the screen. I could tell from the overall shape
of the compiler output if it were done or not and if it was a clean
compile or not. If there were errors, I could restore the font to
something legible; otherwise, I could run the program from a "normal"
window.
