Indeed. Especially impressed that it's got a T11 in it in addition to
the 8085 that helps with the video.
These two will need a good scrubbing but electrically, so far, so good.
I've got more than a dozen LK201 keyboards from this lot too...
which will also need, ah, scrubbing and delousing. The fate of the 10
or more terminals that should go with the keyboards gives one pause--
but we can't save them all I guess...

Yes... although I've seen another reference that says it runs at 56KHz.
That could be wrong. I've not yet found the statement in the VT240
docs that says what the terminal actually sources...
It's definitely NTSC or very close to it.
Yes-- as I guess was confirmed by the reasonable image on a Sony studio
monitor. The image was a little too wide and a little too tall for the
Sony though... which has no controls to reduce height and width but it
did sync just fine.
Are there any recomendations for a converter that can
take RGB with
sync on GREEN as input and produce a VGA (or HDMI) output suitable for
driving a modern LCD?
Sivne you mention the VR241 later on, I guess yoy need to do scan rate
conversion too. The VR241 is TV rate (around 15kHz horizontal). However, I
have just confirmed that two VT240 work with nice clean video on
another monitor so that is good news and very much worth the price ($0) :-)
Excellent. I really like VT240s. I'm glad to have a couple here as well.
