Robotron K1003 RPN made in GDR
Interesting thing I never heard before:

Today showed up a Robotron K1003 made in GDR on German ebay-Kleinanzeigen.
According to the description caught from http://rechentechnik.foerderverein-tsd.d...index.html it works on RPN with a 3 level stack. It also is programmable and has a built in card reader and a printer.
Function modules can be attached / inserted (if you have one :-).

The seller asks for biding.

Here is the link:

Cool photos, but which direction is the red arrow key supposed to point? One has it down and the other has it up.

The both look up to me, albeit one is either dirty or worn down

I'm guessing that is the ENTER (or ENTER↑) key. I think Zaphod's right: the unit in the first picture has a lot of the key printing worn off. No double-shot molded keys!
