This reminds me that my VT102 is on top of my VT52 which doesn't work.
I'd really like to repair the VT52, but I don't have any schematics.
when I power it up, the voltages form the suppy seem correct, the high
voltage for the tube is also there.
Another strange thing: I lack the serial port (I suppose it is serial or
a current loop) there should be a cable coming out of the bottom of the
VT52, but I only have the power cord. Inside there is something that
looks like a connector, but I'm not sure if it really is one.

Does anyone have the schematics for the VT52 ?
Or a hint where I should start looking for common errors ?

DECwriter III is a funny 'Terminal', at least you can always scroll back
to the beginning of your session :o).
I have never seen those DECwriters beeing used, for me it's hard to
imagine that someone actually worked on such a terminal.

Lothar.
