My bezel arrived in the mail a couple of days ago - my congratulations to the C47 team both for the high quality bezel and the fool-proof installation instructions to flash a DM42 to a C47 - the whole process was complete and my coffee was still warm ! I had decided to just use the bezel as an overl...

As an interesting point noticed earlier today that these are primary keys on the Casio FX-82 series (also along with nCr)

Edit : confirming the “everyday calcs” point

Taking a look at the HP48 with three keys and their left and right shifts being the following : [SQRT] X^2 X v/ Y [Y^X] 10^X LOG [1/X] e^X LN This seems quite an effective grouping - albeit for a chemical engineer ! This also gets 9 of the functions together and would allow >R and >P to be left and ...

Don’t understand the need for the x^2 button… I know there was quite a lot of debate over this a while ago but it seems like a luxury and waste of a primary key. I think you guys are doing a great job - can’t wait to try th C47!in the new year. Perhaps the button should be user assignable with [PANI...

Agreed on the number seeming low… I think the addressable market is much larger… I would have approached it from the perspective of how many new potential students come into university each year working on the assumption that most people get hooked on RPN at university. Given that hypothesis could a...

+1 please…. +1 for the physical calculator

Congratulations to all involved - can’t wait for the production run!

Thanks for the update
