How to tell Rev. A

[zjinqui1k]

I've spent the last few hours searching the web and this forum, and I'm sorry if I've missed it, but if it's somewhere, it's burried. Maybe I'm just late to the party. How can I tell if my HP Prime is a Rev. A or Rev. B?

I go to the Help screen, hit "tree" then "About HP Prime," Whereafter, the following is displayed on my screen:

HP Prime

Software Version 2013 8 13 (5106)
CAS version 1.1.0
Native OS Version V0.025.5106
Serial Number 4CY3610GYS

(c) 2013 Hewlett-Packard Development Company, L. P.

[end screen]

Nothing there indicates either NW280AA or G8X92AA.

I only ask because I was trying to update the firmware without success. (This is just sort of standard operating procedure for me with new electronics.) But the thing is that the CK never comes up with anything. It seaches for host for a split second and then just sits there and say's connected.... and will just stay that way for hours.

So, I figure either A) my calculator is the old one that cannot recieve the updates, or B) there is a problem with my CK installation.

Sorry if this is a redundant question, but point me in the right direction if you could.

Otherwise, I am enjoying the upgrade from my 50g.

Thanks.
