What should I know about the 30B?

[TheKaneB]

Hi there!

I just bought a brand new HP 30B that I plan on converting to a WP 34S. Is there anything I should know about it before doing the mod?

I don't care so much about the financial stuff, but is it possible to revert it back to factory firmware, just in case anything happens?

What about bricking the calculator if the flash update fails? is there any risk there?

About the financial calculator itself, how does it compare to my 12C and 17BII?

Sorry for that load of questions but I am very excited by my new calc and I grabbed it for just 42 Euros still sealed in the box!

As a side note, on the 34S even the basic trig functions are under a shift key, but the WP 31S (which in my opinion have a nicer keyboard layout) lacks RPN programming, so I am not sure which firmware to use, I might try both.

Any suggestions are very welcome!
