Tv Oskilloscope

TV oscilloscope was made 1982 for Helsinki school equipment shop.
Where it was sold from there I have no information. If you know, please make an email: moc.liamg|odg3ho#moc.liamg|odg3ho

I was 2-channel scope and it was used to be for first time users.

I was using TV as display.
It used power from TV.
It made screen display with green.
Channel one was blue and channel two was red.

It has color option and it worked well!

I used two inputs, AC/DC switch, position adjustment and time base adjustment.

I would like to say it was a nice design.

Here is schematic diagram of the device
