HP 49G+ keyboard return
I've had my 49G+ since August of 2006. The "0" and "." keys have broken and are loose. I called HP yesterday and they are sending me a new one.

50g questions, programming and OS [open/closed book examns]
[re: storing potential "crib sheets" on SD cards] At one time, old HP48 series calculators were sometimes permitted only _if_ they were "memory cleared" (and RAM cards removed) before a test (and also sometimes only if their IR transceiver were taped over); it's not impossible to conceive this being extended to ... 12 Oct 2007 20:38
