Yes but the bundle was rearranged :-)
The HP41 IL modul is now missing and the parts were arranged differently with new pics.

I think the seller is not professional and no HP collector.

EBay -> HP-35S - $585.

It's not inflation, it's madness.

Good to hear. I have three of four of them... finally I am going to be rich! I will build my own Mars rocket like the other billionaires ;-)

Here is an interesting piece of history for sale:

Vintage Unicom 141PF Calculator - Busicom - Grey Intel C4004 and MCS-4 set

$20,000

Is the price justified? Perhaps it is. CALCUSEUM lists a 10/10 collector value.

This time it sold for "only" 900 Euros. I wonder if we will see it again soon...
eBay Germany has completely removed the fees for private sales a short while ago. So you can keep buying your own stuff as often as you want without having to pay anything. He's probably going to repeat this game until he is happy with the result.

I’m afraid I will be dead before TAS removes fees for private sellers. But I still won’t be selling and letting them take my money, I just won’t FEEL THE PAIN. LOL

When you consider the effort that went into making this calculator then, I think, this price is justified. Actually, this will spur makers to start trying to design their own calculator with what they(we) have to hand like the 6502,Z80,AVR,PIC and 8051.There's nothing wrong with old electronic technology, it is perfectly usable today(hp15c ce). In fact, the latest electronic technology software support tools are generally out of our price range, e,g., ARM uC's compilers.
Well, I have been trying to design my own calculator using the 8051 and I can't seem to get the bcd floating point to work but I keep trying, I'm coding in assembler.
There is plenty of floating point code around for the 8080 and others if you want to check those for inspiration. -J

If you are watching to think about to buy - too late, it‘s sold last (here in Europe’s) night

Just to clarify, while the HP-15C CE is functionally the same (same ROM and appearance) as the original HP-15C, the hardware inside the HP-15C CE is not "old electronic technology" and is 100-150 times faster than the original HP-15C.

Quite correct, but to tell you the truth, I'd prefer to have the original hardware any day.
