The Busch 2090 Microtronic Computer System was a 4 bit microprocessor trainer from the early 1980s, similar in spirit to the KIM 1, Microprofessor, and likewise CPU trainers of that time. It was made by the company Busch Modellbau GmbH located in Viernheim, Germany.
This Arduino-based Microtronic emulator has some features not found in the original Microtronic, such as SDCard-based program storage, an LCD display for programm debugging and CPU status display, as well as Emic 2-based speech synthesis.
Each Monday is ArduinoMonday here at Adafruit! Be sure to check out our posts, tutorials and new Arduino related products. Adafruit manufactures the Arduino right here in the United States in cooperation with arduino.cc. We have a huge selection of Arduino accessories and all the code and tutorials to get you up and running in no time!
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
