50g

Hi,
I'm new to the 50g. I have the 48gx and several other HP's. (Hooked
on HP's since the HP35)

Are there any good books or PDF files available that have more info
than the "User's Guide"? Something like a reference manual and
something that tells how to do things like check your ROM version.
Also maybe a good programming guide.

Thanks,
Ron
