I ordered one and it has just arrived!
1. The machine is built in China but bares a label "German Design" on the back.
2. The LCD has three areas:
Bottom row with 11 digits + sign
Upper row with 11 positions, 5x7 pixels each, plus 4 arrow annunciators
Top row with the following text annunciators:
BEGIN YOERS AMORT CASHFLOW STORE RECALL SHIFT NAME
3. The keyboard is ok even if a litte stiff. The contrast for the shifted functions is somthing between ok (grey on red resp. black) and bad (grey on grey)
4. The device connects to a PC. It doubles as a numeric keypad and can upload some stored information (see below) to the PC app the can be downloaded from www.FAF-verlag.com (registered users only).
Only a few words about the functionality:
Its a TVM machine, no programming, no statistics. TVM is very complete (at least for me who is a TVM hobbyist).
It stores up to 40 complete TVM records which can be named. This is the YOERS function: Yes, OK, Exactly, Right, Sure. The records can be sent to the PC for documentation purposes.
It does cashflows but I haven't checked that out, yet.
As a calculator it works with complete AOS, including parantheses and precedence (exponentiation, multiplication, addition). You cannot enter base 10 exponents but the machine handles and displays numbers up to 10^9999 with 11 digits precision.
My preliminary conclusion: The machine works as designed. Its meant as a tool for financial pros to do quick and reliable TVM calculations for or together with customers. The results can be archived and formatted an the PC.
