Interface HP42S to Notebook PC?


Is it possible to link the HP42S to a HP Notebook PC using the IR port. I am trying to get a ROM Image from the HP42S to use with an emulator, available on the net. A Mr. Garnier describes the process of transfering the ROM contents, but this requires a HP48, which I do not have.

Can someone help?

Thanks and Regards


The problem is that the IR in the 42 is not compatible to that on the laptop computer.


Sorry, you really require a HP-48 to do this...

...or need an interface like Christoph showed in Allschwil. (Not for sale, AFAIK.)



Thanks mates, for your help and comments.


You can try Thomas Okken's Free42 (No ROM required):
