For all of its faults it was still the market leader.
Did you know you could plug a B&W TV camera into the back of a VT100 and see
the picture on the screen? I did it at Dec Park (Reading UK) one day and
drew a large crowd.
I can remember the tiny on/off switch and the vertical DB25 connector but that
is all I recall about the back of a VT100. I guess there must have been a BNC
connector? I do vaguely recall occasionally having to dissuade academic staff
from plugging their thinwire ethernet segment into the
back of their terminal but
I don't remember which type. I suppose it was
probably the VT100.
Did the terminal automatically sense an external video connection or was it
necessary to manually disable the video generated internally? I guess it was
probably expecting 525 lines, 60Hz but could cope with 625 lines, 50Hz?
My VT220 has a BNC connector on the back but in this case it is an output. It
produces a nice picture on a monochrome 625 line 50Hz monitor after adjusting
the vertical hold.
