Well, I figured out the secret shortcut for “swap” and “review”. But I still havn’t figured out where the function is that converts a decimal into a quotient. I’m afraid they left it out.
Boy! This thing is really slow. One very deadly flaw of the 50G is that I can tap the buttons faster than the thing can register them. That’s not good.
I’ve been looking around to see if I an pick a 50g up for mysself at anything near the price you got. No luck so far.
On the keyboard, I’d been warned the default key response time is too slow. The fix is to set the KEYTIME variable to something like 1/3 to 1/4 the default time, e.g.:
400 ->KEYTIME (when in RPN)
You can write it as a short program and set it to run at startup (by naming it STARTUP, I’m told.) I understand that there’s an enhancement request in at HP to make the default time shorter, and user settable without resorting to a program.
I’m not familiar with the fraction functions, I’m afraid.
