Nota: Es ist bereits vorhanden in CB-Emu pakket.

As was already mentioned before, one of the EPROMS says "polgar". I think this may be (based on) the bookrom part of the first version of Polgar. It's partially unused in Mephisto T+T.

Does someone have a dump of first version of Polgar? Or have a this chesscomputer in possession? Does the test mode (MEM->INFO) say "TEST-PROGRAMM" instead of displaying the version number?

I'm not sure this is a prototype of Polgar. A prototype of Polgar would make more sense on Polgar hardware.
