Internet programs for HP48/49/49+ calculators


Hello, everyone !

I'm a long-used HP calculators developper, however I've just discovered this interesting forum.

I'd like to know what you think of surfing the internet using a HP48G/G+/GX or HP49G or even HP49G+ calculator.
It is indeed possible thanks to hp->modem connection, or with ip-masquerading under linux, in that case the linux box acts as a relay between the HP calculator (49G+ for instance) and internet.

Then, we install a TCP/IP library, that handles the internet connection, called Usinagaz.

You can visit
for more information (there are a web browser called Navigator, a mail client "Mail Prime", an IRC client, and some other tools).

Best regards,

Yoann Désir.
