Multi Calculator Kit

[rprosperi]

I'll take one assembled kit please.

To be clear, is this a complete calculator, or just the CPU board?

Which subsystems are included, among:

CPU/RAM/ROM(s)
Power supply
Keyboard
Display

And does the board have a USB interface (e.g. for updating and/or loading/saving programs/data?)

Note the bold but clear indications of addiction here: "I'll take one please, but what exactly is it?"
