Is that a USB port peeking out under the keyboard?

Thanks guys.
All answers in the one post:

It's a bit smaller in area than 50x50mm, quite comfortable to wear.

No, it's not a USB port, but it could be. It's a "universal" I/O port that supports anything you can plug in, like RS232, IrDA, USB, or your own custom gadget. At the moment I only have an RS232 adapter for uploading and downloading programs (yes, it might very well be programmable ;-))

Note the WIDE ENTER key :->
Yes, the buttons are tactile.

Oh, and yes, it's both RPN and Algebraic.

And, no, you can't buy one, yet...

Dave.

Any chance of an RPN-only model (eventually) being available?

You can permanently switch it to RPN mode.

If you are scared that the algebraic mode might pop out and eat you alive at some point, it could be easily removed from the firmware. And the keypad overlay is replaceable so you could have any key layout you want, if you didn't want those horrid parentheses.
Perhaps I should add a "nuke algebraic" function that self erases the algebraic code from the firmware...

Great to see this "in the flesh" Dave!

Now, where's the emulator so we can run and critique your dream calculator software? 8)

Emulator, what's that? :-P
I'm more of a hardware guy, so I like to scratch'n'sniff bits of plastic coated silicon instead of 1's and 0's.

No doubt someone will do some "real" software for it eventually where the 20th digit matters, and the war between BCD and floating point can rage eternal.

It'll be essentially an open design.

Dave.
