Slight detour on the way up from the dwagon-cave; now that the Saturn is sorted, I went out to the garage and finally got the first coat of urethane down on the Anniversary Project table. We'll see if I prepped it right; it's been sitting a while. But hey; the stain is definitely dry.  :-DD

A " Signature Analyzer " wow that sounds fancy high tech and mysterious all at the same time.... do you hook up a camera to it and it reads a hand written signature and tells you if it's been forged or is legit ?
Pretty high-tech for the day indeed !  :-DD


OK OK... I will go download the user manual to see what it does ...  :-//

The HP noise generator at the bottom looks pretty nice, it deserves some cleaning for sure, please !  :-DD

Yes but the upper right unit matches the page number, rather the point...

Just starting on sorting 60 or so DIL8 packages here.

I found an IL300-F ... an opto-coupler. OK no big deal but... that's no ordinary photo-coupler, look at the datasheet, that's one hell of a fancy one !

Just search this forum for IL300 for quite a lot of information on this device. I use it all the time for isolating audio. See schematic with some real data.:

The style of that schematic of this audio amplifier looks like a project from "elrad". Hmmmm....

Maybe, but the circuit was further developed based on the data sheet examples and tested by me. Moreover I produced the schematic with Abacom SPLAN 7 resp. which today is SPLAN 8
