Be sure to find and attach the clear plastic keyboard overlay for the programming commands.
Also, be sure to NEVER rub the print on the overlay. The ink has been applied to the exposed surface of the overlay. It rubs away very very easily, beginning with the initial act of applying the overlay sheet to the keyboard. One would have thought a little better attention to detail would have been warranted.
The functions on the overlay are accessed from the keyboard by pressing and holding the blue shift key while depressing the desired function. The same technique is required to program an UP or DOWN function. Otherwise, pushing those keys scrolls through the program.
The 30b is a lot of fun....The keyboard has a nice feel and it's really fast.
The HP 30b itself is an amazing device. It's the fastest handheld anyone has ever produced.
Here is a HP 30b version of the well-known Savage Benchmark.
In Prgm 0:
1 STO 0
4 Lbl 00
15 DSE 0
16 Gto 00
Set the HP 30b for RPN, RADIANS, and FIX 11. Then execute:
The result is 2499.99946106 (perfect would be 2500). Execution time (from a stopwatch) is 6.5 seconds! That is the same numerical result from the HP 50g, which takes 65 seconds to do the same.
The HP 30b is ten times faster than the HP 50g! (At least for this application.)
