Odd accessory for the S2

Hi

I bougth an original user manual for the Asahi Pentax S2. I hoped it was the user manual for the S2 "Super" which was only sold in Japan, but it is for the first version of the S2.

On one of the pages this odd accessory is shown. Can anyone here tell me what it is?

Thanks, Baard-Einar

I would guess attachments for instruments like an oscilloscope.

We used something like that with a Polaroid camera in one of the labs I worked at in college back in the 70's.

Yep, the Japanese says that it's an oscilloscope adapter. It's available with 133mm and 75mm ends and the 133mm cost 6000yen, which would have been a fair old whack at the time. I bet there's a few dusty examples in the drawers of Japanese science labs...

Back in the analog only days this was the only economical way of recording CRT output. Pen recorders weren't fast enough to record quick spikes.
