No. At the very least you need the 48gx and the 49g+, and both
of them are really handheld computers.


But if we rephrase your question as:

# does anyone know if, with some sort of cable configuration,
# programs (rpn) from a 48gx can be directly loaded into a 49g+
# (without any other computer).

Yes, there is a way, and you don't even need a cable: list the program
on the 48gx, read the listing, and type the program into the 49g+.
Yes, it's slow and error-prone, but with careful proofreading it
works. For very short programs it's even practical.

But if you want a cable directly between the 48gx and the 49g+ through
which you can transfer programs, such a cable cannot be made just by
wiring together the connectors of the two calculators in some suitable
way. There would have to be at least a suitably programmed
microcontroller somewhere on the cable -- and that microcontroller is
really a small embedded computer. And you didn't want any other
computer except the 48gx and 49g+....

I have always used ASCII transfer to PC,
which is then my back-up place anyway
Note that you can download useful www.hpcalc.org
stuff directly with your calc
you will need the PC anyway so I use it to transfer source text files
48SX & 48GX & 49 are not directly binary compatible

Very true -- the requirement "without a computer" seems quite odd to me.
