Default Gould OS3350 Manual Wanted, for loan or purchase please

Hi!

I'm trying to research Member "Radio Wrangler" David's suggestion for a V.I.T.S. Generator/Inserter and all the circuits I can locate so far use at least one special/custom, programmed or ASIC device!

Has anybody got a Gould OS3350 Manual they can scan or loan me to scan, or purchase please?

The '3350 has a special selector switch on its front panel for these pairs of lines, so me thinks some of the circuits from the '3350 night be a useful starting–point!

. . .I've just gone through all my big parcels upstairs ready to start moving them into my shed and discovered amongst them, another Gould OS3350 in the flesh, so I've got a legitimate reason for asking if anyone can help now – I must have bought it a few years ago, and then totally forgot I had it, as per usual!

. . .So I could certainly draw out the TV Line Counter bits, the Picture Display bits and the special Line Pairs Trigger Selector Switch bits from the actual Oscilloscope itself, but it's not a task I relish in the least bit!

Hello Chris

I think this was also the GPO "Oscilloscope type 18A" I have two of these, neither work!! but also no book!

I do have a scan for the OS3500 which is what the 18A is based on but none of the clever video bits.

Evening Brian!

. . .That is indeed the model I refer to in my query, but mine is "Gould" branded in their standard front–panel colouring scheme with red and white knob caps rather than the black knob caps and black front panel yours has !

. . .I think (emphasis on the think!) that the Y Amplifiers, Timebases and the normal triggering circuits are based on the OS3000A/OS3300B design, but the TV Line Counter/Trigger Line Pair and Picture Display facilities were the added bits!
