The Mailuefterl (German for "may breeze", an allusion to much bigger US computers like "Whirlwind" or "Typhoon") was the first fully transistorized computer in (continental) Europe. It was built at the Technical University of Vienna (Austria) from 1955 to 1958 by Dr. Heinz Zemanek and his team. Now the machine does not work any more and can be seen at the technical museum in Vienna.
In 2007 I wrote an emulator for this pioneering machine as a Java applet, and now ported it to JavaScript to make it usable again in modern browsers. You can try this historical computer as an emulation in your browser at my site at http://members.aon.at/nkehrer It contains some original and self-written code snippets to play around with, and I also shortly described the instruction set of this old machine.
