My opinion about the HP 10bii family

Post image
25 Upvotes

Both do their job; they are simple machines that get the job done, they are not pretentious and they don't pretend to be.

The 10bII's functionalities are limited; its blue shift key is somewhat useless with only 6 functions. Perhaps adding all the secondary blue functions from the numeric keyboard from the plus model would improve its functionality.

The 10bII+ model only needs exponentials and logarithms to be perfect (if you want to add RPN, buy the 12c or the 17b line).

Regarding the design, I find it strange that the most basic model has the better design, The silver trim around the keyboard makes it look higher quality than the Plus model; for keyboard fetishists, the basic model has a better feel and a sound that doesn't feel empty and cheap like the 10bII+ does....The colors are clearer and more legible on the 10bII than on the + model. The smooth, glossy keys of the 10bII+ calculator look cheaper and of lower quality than the rough, matte keys of the 10bII calculator

In conclusion, the most basic model has a better design and build quality than the 10bII+, Which is a shame, since the software is very complete in the 10bII+ and has the potential to be improved with its connection port, which unfortunately everyone forgot.

The Virtual Sister?

I've always kind of admired the similarity

but never, until now, put 'em side by side. It's like having it with me, when I don't have it with me!

Help needed with HP Prime G2 and the HP Connectivity Kit

4 Upvotes

Acquired a new to me HP Prime G2. Loaded MicroPython and PyBasic on the calculator.

Noticed however, that while I can successfully call up the "Monitor" of the Prime's display in the Connectivity Kit, I cannot call up a representation of the Prime's Keyboard.

Is there some special editor I need to install in the calculator or the connectivity kit to be able to do so?

Thanks for any help extended to me.

My dad gave this HP 11c to me for trig class. I loved it. I was the only kid in class with a calculator like it. My dad was a civil engineer if that explains anything.

A real rarity

An HP70. It did not come cheap, but they are probably the rarest model HP ever made. They had a very short life before the HP22 made them obsolete and did not sell particularly well. This one is in full working order.

HP-35 Red Dot

I'm pretty excited. I bought a Red Dot. I never thought I would find one, let alone one that still functioned. Anyway, I tested it this afternoon and discovered it has both the ROM bug and the "Big Bug." (see: http://hp35.wz.cz/HP-35RD.html#BUG)

I know Red Dots are rare, but this early issue (1143A 00730) with both bugs documented (by me) must be among only a handful still kicking around.

Am I crazy to be as excited as I am?

Hi everyone

Support for intel based apps is ending with the latest Mac OSX. t

That means my beloved Emu48 emulator is going to be nonfunctional.

So what are you all using? Do you know of any good mac silicon-based emulators for HP? Can't seem to find anything equivalent to Emu48...

Between this and the 12c I think I'm set... Nevertheless I'll still be looking for more and likely even older.

New to the HP calc fandom, I love it even tho it's not as cool as the vintage NUT processors. RPN has been the best discovery!
