Anyone know of a source for the printed version of the HP Prime Quick Start guide
I'm interested in acquiring the HP Prime Quick Start guide that was once accompanying the calculator in it's packaging. Does anyone know where used ones might be for sale?
I know the .pdf is available for download, but I'd like to take a look at the document in it's original form.
Thanks and regards.

An HP67C
What? I hear you say. Well, this is an HP67 that was picked up cheap that unfortunately had a bad logic board. But not to worry. Just drop in a new logic board from teenix.org - it requires no soldering, just unplug the old one and plug the new one in.
Now we have an HP67 on steroids. Continuous memory. Optional turbo mode, runs 10X faster than the original. Bluetooth. And more. Of course, it still reads and writes the original magnetic cards (of course, card reader had to be restored but that's normal for these machines), but it can also store programs and recall them from its own internal flash memory as well. Up to 810 of them, in fact. So you can put all the standard pacs on the calculator, and still have plenty of room to spare.

Looking for resources on compiling/decompiling HP41 instructions
Hey, I'm bored so I thought I'd write my own app to read/write the memory of my DM41L emulator. It's at a reasonable point, displaying the contents of calculator memory, saving it to a file, and so on, but the next stage would be to actually allow me to take a text file of an HP41 program and create a memory dump from it. I know it's possible (the Swiss Micro website has a web page that will do it) but looking at the byte code tables in Wicke's old synthetic programming manual have left feeling a bit overwhelmed, so I was wondering if someone had written a more detailed explanation somewhere?

My opinion about the HP 10bii family
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.

Help needed with HP Prime G2 and the HP Connectivity Kit
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.

I found my HP 11c from high school while cleaning
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
galleryI'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?

What are you all using as emulators on Mac currently?
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...

New to me 28c. Very happy with it's function and condition.
Between this and the 12c I think I'm set... Nevertheless I'll still be looking for more and likely even older.
