It’s quite a capable and programmable calculator in the same style as the HP 41C, HP 41CV and HP 41CX. In other words it looks magnificent.
This calculator’s capabilities include BASE-n, statistical functions, fractions, keystroke programming, complex numbers, unit conversions, integration and an equation solver. There is no indirect addressing or branching unfortunately.
It has quite a lot of memory, 30 kB for programming and 800 memory locations.
Although being an excellent way to celebrate the HP 35, not everything is perfect with this calculator. There are some firmware bugs and the firmware is not upgradable. And although a welcome addition, working with BASE-n numbers is extremely cumbersome and needs numerous unnecessary key-presses.
This Wikipedia page has quite a lot of useful information on this calculator.

This one was a birthday present from my wife. Thanks, Catheleijne!
