HP-41CX for sale

[Thomas Puettmann]

Yes, GAO was at Aegediimarkt. I also passed there on my way from Coesfelder Kreuz (Math+Physics) to the center or the train station.

Of course, I remember Guttermann. I bought my beloved HP-42S there.

And I agree, those were the days. Although my current activities with fischertechnik (see signature) bring partly back such positive aspects of the past.
