Several years ago I worked for someone who had a few dozen surplus
Moniterm 19" monitors, and most of them needed the same repair - the
first-stage video amplifier transistors needed replacing, and they
needed general alignment/color adjustments. They work well at
1280x1024x60hz, but are very unusual in that they use DIP switches to
control the "fixed" frequency at which they operate; therefore can be
used at other resolutions and refresh rates too, with enough patience
and tweaking. My only reward for this work was that I got to keep one
of them; and now my dad has it. He uses it with a Worldwyde S3-Virge-
based PC video card. This card does line doubling/tripling/quadrupling,
and padding, as necessary to force all video modes into an approximately
1024-line non-interlaced format.
They are color and have 4 BNC inputs (composite sync).
I have another old CAD-oriented ISA board which worked with this monitor
too, but it could only do 16 colors, and did not do text mode at all;
it only worked in Windows 3.1 and AutoCAD 10. That card (and docs,
drivers etc.) are available for trade or whatever if anyone wants it.
These monitors do not generate a full-screen picture; there is a large
black band around the outside. Their excuse was that they wanted to have
a very precise image, so that straight lines look straight, and therefore
avoided the edges parts of the CRT. I thought it was a lame excuse;
but if I try to make the picture bigger, it gets distorted. The CRT
is by Sony I think, but they probably designed their own electronics.
I have technical docs on these monitors (somewhere) if anyone here
ever needs it.
