New kid - where to start

[HP67]

Hi and welcome,

I can't help with the 42 or 41 models, but if you think you might enjoy a FORTH-like language on a calculator as many of us do, then the 28/48/50 are great choices. Sadly they're all out of production but 48s in nice shape in many variants are available at reasonable prices. The S and SX are probably the most beautiful calculators HP has made aside from the 67 but the G, G+, and GX are more powerful. The 50g is more powerful yet but went out of production quickly and is now selling for exhorbitant prices.

I run mostly Linux and UNIX so I understand your frustration at the connectivity options in general. However Kermit works perfectly with the 48/50. There is also a port of the assembler for the 48 models which runs on Linux and supports user and system RPL also.

Of course, running Windows in VirtualBox etc. might also be an option if you want to try the many Windows-only tools.

I'm sure you'll get much better answers from the rest of the guys but since nobody replied yet I thought to put in my 2C.

Some intro. to RPL is here https://www.hpmuseum.org/rpl.htm
