Nope, TI 83

It's not a real calculator if you have to use shift to get the exponent 

[capt bullshot]

@Neomys Sapiens I am bidding for one, currently ...

Look what I found in one of the not yet cleaned corners ...

An HP48 calculator, as far as I recognize.

Nope, TI 83

Damn, I'm Pwned now.

Now for something completely different:



Can you spot the HP device? And what make and model is the calculator?

my favorite calculator is:

saskia@morgoth> bc
...

[bd139]

dc is better   

bc was actually a preprocessfor dc originally on V7.

Ooh yes, I am interested, Sir!

Thank you very much for pointing at it.

And? Did you get it for 125 Euros?

Nice bench!

@Kosmic - How many petaflumps izzat?

Well for me, the real problem is in games, like WSC real09, written for XP and Vista but also worked perfect in Win7 but will install under Win10. This is also true for the most part with all of my C&C collection of games. There are now online versions of C&C that will run happily in Win 10 but you cannot buy the games on DVD/CD any more, so the urgency to set up the Dell is not as critical as it once was and besides, I don't get that much time now for games because I got back into electronics and TEA  However I would like to get WSC09 working again because they never did an updated release of that fabulous game other than on PS4 and I'm buying a games' consol just for that.

Now I'm not a programmer by any stretch of the imagination but the main problem as I understand it that programmers like to save time and work will often make calls to sub routines within the OS itself rather than write their own code for that routine and when a new version of OS comes out, if the programmers move those builtin routines to another location then the games will not run or load correctly etc because it is making a call to a location that now contains completely different code and hence the problem.

Ain't I a stinker...?

*out, standing in my field*

No you're not a stinker  Hmm, I might just get that download, probably worth it just for the enhanced graphics  But its the WSC09 that the real pig, because neither Steam or Origin have that available for PC updated for Win10. As an ex team snooker player, I really enjoyed potting a few virtue balls and clocking up a few 147 breaks. Helps to refresh your mind and clarify your thinking, so hopefully one day it too will get remastered.

My Rubidium reference vs my GPSDO.



I probably need to find a cesium reference to know who's right and who's not.

Isn't GPS controlled by NIST & space rubidium oscillators?

[bd139]

Yes. Casio are excused as they're quite decent. I've got at least three here myself

Another one from the HP Harrison 6824A bipolar power supply / amplifier.

Now as an amplifier.
Situation: Load Test.
Input: 2.5V RMS sine wave 400Hz
Output: variable depending on amplification factor (adjustable)
First screenshot: oscillogram of the output waveform at 118,4V peak-to-peak. No distortion/clipping visible:


Second screenshot: output waveform at 121,6V peak-to-peak. Beginning of clipping at the positive peak visible:


Third screenshot: output waveform at 125,6V peak-to-peak. Clipping at the positive peak clearly visible. No clipping at the negative peak. Hmm.


Fourth screenshot: output waveform at a slightly higher amplification factor:


This looks strange to me; asymetrical and with a jump back like a limiter kicking in delayed -inspite of the negative half of the amplifier being able to deliver the peak voltage (?).

Fifth screenshot: output waveform with an even higher amplification factor:


The limit seems to be stable, the sine wave gets cut off "earlier" with higher voltage levels as it is to be expected.
I'm curious why the amplifier of that 6824A doesn't clip symmetrically.
Have to explore the service manual parts more deeply..

Didn't notice that my siglent gave hints to me while capturing screenshots..

Well it was only trying to help stop you falling asleep at the wheel.   

Yep, lean on any of the buttons and Help pops up.

Congrats, it's exactly the same model

don't think so.  the master clock for gps used to come from the us naval observatory.

maybe it changed?

don't you still owe us pictures of an hp5370a?  (or was it a "b"?)

[kleiner Rainer]

I am also in the "Casio Club". Scored at our local flea market for 35€ or so, with all accessories.



If I have read correctly, the calculator on top is not a"real" one, because you have to shift not only for exponential functions, but for ANY function

holy shit.  did bd just come out? 

welcome to the world of "=".   

shall i count you as recovering from "rpn"?

you should start attending meetings or risk a backslide.

[bd139]

They’re standard here for schools so I need to know how to use them. The 991EX is ok.

Just not as ok as the 35s

To me, this poor dog is looking very sadly, like someone who's missing his beloved HP48G.

what that look really means is:

Alas, no. I was the one offering 120 bucks. Got to continue the tradition of "second best offer".

I just wish I knew how much the winner was willing to pay ... Or better not. If that actually was the limit, I'd be really pissed off.

Hei, anybody here in need of an AC calibrator from YEW, the YEW 2558?

Sadly to hear this. 
If I'd bid for that thing, I think I'd have set my limit to around 350 Euros. Usually, these 3330B are going for much more.
More luck next time.
