MAME now emulates a Stasi numbers-station speech synthesizer
Gerät 32620 was a digital speech generator, developed in the early 1980s and was used by the Stasi for sending secret coded messages via the mysterious numbers stations that used to be operated on the short wave radio bands. The device is known by different names, including Eiserne Frau (iron lady) and Stimme (Voice).
A MAME emulation has been created. Thanks to the work of the Crypto Museum (https://www.cryptomuseum.com/) the ROM images and documentation for this machine is available. A preliminary driver was written by natarii (Twitter thread) which I’ve taken and reworked.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
