HP48GX

[Steve Simpkin]

Vagn,

I am a huge fan of the HP-48SX and have used mine as my daily engineering work calculator since I bought it new in 1991. That being said, €450 is a very high price to pay for a calculator you may or may not like. I might suggest you purchase a used HP-48SX/GX or the very good HP-50G or play with a free emulator first to see if you even like the RPL models. There are some people on this forum who never did transition from the traditional 4 level RPN calculator models to the unlimited stack RPL models.

I also recommend looking at the excellent book HP 41 - HP 48 Transitions by William C Wickes.  It helps explain the differences between the RPN and RPL way of doing things. It is available on Disk 12 of the MoHPC documents on DVD.

To see the different display contrasts on the HP48 models, look at Post 43 of the following forum thread:
