Oooh, look what I found!

[Steve (Australia)]

As I was giving myself a birthday treat today (going through my HP collection and cataloging things) I came across a piece of paper that I had not seen before...

HP-41 System Demo

This appears to be the instructions that went along with a tape that was suplied with the 82161A cassette drive.

Whilst I have heard of this before, I've never seen one. And it happens I had one all along. :-D

Now though, I am pining for the tape...

Does anyone have a copy, and the means to duplicate it?

I can provide a new sealed tape, and a copy of the document (4 whole pages!) should you be missing it.

Oh, my age is the product of two prime numbers. The larger is product of the smaller and the square of the next highest prime, less the difference between them. I am not the oldest person on this list.

Hi Steve,
congratulations to Your -I calculated it with my 41- 35th (right??) birthday.

Can you scan theese 4 pages and send the images to Dave, so that he can publish them? I can also help to put them into one pdf-file which may be published here.

Have a nice birthday.

I think you're off by one. The correct answer appears to be 34. Then again, I didn't use a calculator (no, no C++ this time either) so I could be wrong :-)

Tes, you get top marks for determining the answer to the question, however I get an absolute fail for wording it wrongly. Worse than that, I actually created a spreadsheet to check that there were no other feasible answers, and there is 34 sitting in the age column.

I should have said "plus the difference between them"

so the two prime numbers are

2

and

19 ( 2*(3^2) + (3-2) )

I really should give up this mathematics thing :-(

[Viktor Toth]

Oh, so 38 it is. But who's Tes (assuming it's a name)? :-)

Viktor

[Steve (Australia)]

Yeah, I can scan it -- I'm somewhat surprised it's not there already though. Give me a couple of days...

Oh, and no, I'm not 35. That is not a solution to:

My age is the product of two prime numbers. The larger is product of the smaller and the square of
the next highest prime, less the difference between them. I am not the oldest person on this list.

5 and 7 are not the 2 primes since 5*(7^2) - (7-5) <> 7

Steve:

We could encode ages as HP models: Your age seems to be the most powerful Spice, and the next year you will have the first Classic.

As per myself, some months ago I upgraded from the most expandable model to a "function set compatible" one (but not expandable); a model currently missed by so many ...

If HP listens to the people posting here, there should be a new RPN model to which my next birthday could be mapped ... :-)

[Thibaut.be]

The 2 primes are 2 and 17.

One could be tempted to say it's 2 and 19, but the "difference" between the smaller prime and the next higher prime should be considered as absolute value.

So age is 34.
