I know the top circuit is a Klass circuit the scope add on circuit i have not seen since i found this which must of been a fair few years ago if not a decade or so .
I would think its all yours Klass ?
I came across this checking some old circuit print outs ...any case it needs a home here for others to try .

The top circuit with the bold lines in mine. It is also in the NBTV Handbook and there is a PCB for it. It is only a sync separator, NBTV video in and H-sync and V-sync out. The description is also on the http://www.nbtv.org website. Click Handbook, or Clubshop and you will find the full description.

Yes Klass i know of this Sync Separator i have made it in the past , i was thinking the circuits for the scope x y and z were yours too i think its ON1AU top of the page i was thinking it was your Amature radio call sign ?
I can't recall where i downloaded this as i have never come across your circuit with the XYZ circuits again ...a mystery !
