Things I've Built

Busch 2090 Microtronic Computer System Emulator - A 4 Bit Arduino-Based Homebrew Computer

The Busch 2090 Microtronic Computer System was an early 80ies microprocessor trainer, in a spirit similar to the KIM 1 or Microprofessor. This Arduino-based emulator of the MIcrotronic comes with SDCard-based file IO, LCD display and Speech.
