I really like how these seem to be coming up more regularly.
Studio 868.
Really handy for your EDC. πŸ˜‰

Just for fun: This is the that started it all. My dad's .
He used it during his communications engineering studies in the early 1960s.
(I think he started around 1960, before my parents were getting married in 1961. The toaster we still use was one of their wedding presents.😊)

He gave me this one some time before I took up my own studies, but I didn't learn how to use it until well after my university time. He tried to teach me but gave up, eventually.

Re FUBAR:
Here is a detail of the trial one. At some point the frame bracket broke and it seems it was glued.
It holds up fine but looks terrible.
The damage wasn't visible in the offer but the spares make up for the 10 EUR I paid.
So this donated its case, cursor, and accessories to other slide rules. Fair enough.

After new glues arrived today, I tried and glued the two broken slide rules.
One is pretty much fubar, so that was the trial run. Had a bit too much glue and thus some cleanup to do, but it worked just fine. Second one is supposed to be used, so I was a bit more careful apied what I learned.
Pretty nice again. Not a shelf queen but very well usable.
Awesome!

What grind my gears...
When sellers hide damage, no matter if intentionally or because they don't care.
See this 0968 here? It's rough and has quite a bit of use, but also has a broken frame.
Yes, it can be patched, but why not tell beforehand?
I paid 12 EUR and the cursor alone makes up for that, but I'm still disappointed by people.

I have a frame and slide from one of the recent repairs, I think. πŸ€”

Checked and yes, I have a better frame. Also needs gluing but that's quite inconspicuous as it's just a glue bond that broke, rather than the whole bracket.

Crusty little bugger.
An 868 .
Had a lot of fingerschmutz and corrosion. The green stuff probably comes from the golden decal under the cursor and doesn't clean off completely.
Had it apart to the last screw. A lot of cleaning and a proper adjustment later it's good to be used again.

The sleeve needs sewing. So far I gave it a little shine. Might visit my trusted shoemaker around christmas. Maybe he can help me out.
I wonder if these could be reproduced. Basically just two leather pieces sewn together. The most difficult part is this stamped logo.

Back in the M75.
Decided to give it a battery in isopropanol to remove flux residue and dirt.
The red brick turns out to be some kind of potted circuitry. Not sure what that is as I haven't found any schematics yet.

Now that my major (or whatever) has somewhat returned I put this on the list.
They've been sitting in a box for way too long.
This is the basis for a class kit of Studio that I collected over the last years. They need cleaning (the cases are already soaking), minor repairs, and probably adjustment for the cursors.

Side note: They are from different revisions. Colours differ, and the cursor design went from metal to plastic in different shapes.

Apparently, I can repeat most of my shenanigans over here. 😁
Here are my favourite ones. and by .
Both were top of the line slide rules for scientific work. (as far as I know)
The HyperboLog is quite hard to come by while the StudioLog surfaces in waves every now and then.

A little bit of history: (Dennert&Pape) in Hamburg was one of the leading manufacturers of slide rules. With the upcoming turn to electronic calculators they tried to keep up with these. The M75 was produced 1975-1985 and was intended as a successor to slide rules. As far as I can tell that did work, just not for Aristo.

Going by markings on the box one of these was purchased in 1976.

Well, one is flakey but somewhat working, the other remains dark.
I guess they need a proper clean and a little bit of TLC.

Now that's really neat!
I wanted one of these M75 for ages.
And what's the best part? I got two!
One got a smoky perspex cover, the other has a leather pouch. They come with the power supply.
One looks wonky because I opened it to .
Didn't have any, though.

Just look what we have here.
Won an auction that I somewhat forgot about and today it arrived:
A pretty complete . Just needs a clean and a place on my desk. Comes with the hard case and a set of stands.
(This one is pretty hard to come by. I'm lucky to have snagged a total of two by now. Still looking for a HyperLog.)

They just make them like this anymore. Or at all.
