Pi Pico Enhances RadioShack Computer Kit
The Radio Shack vintage microcomputer kit from the 1980s, originally built around the 4-bit Texas Instruments TMS1100 microcontroller, has been revitalized with a modern twist using a Raspberry Pi Pico. While Radio Shack was once a haven for electronics enthusiasts, its decline led to the nostalgia for its DIY microcomputers, prompting this innovative project.
The kit, featuring a keypad, switches, and status LEDs, provided users with hands-on experience with the TMS1100 microcontroller. In this updated version, the Pi Pico serves as a digital clock, driving the antique computer by sending switching pulses through a relay. Despite its age and limited processing power, the microcomputer continues to serve as an educational tool, now enhanced by the modern capabilities of the Pi Pico.
Although the microcomputer’s slow clock speeds and reliance on a relay module may hinder its performance, its simplicity allows for a more intuitive understanding of its operations. With the integration of the Pi Pico, the vintage kit gains newfound functionality and relevance, bridging the gap between retro electronics and modern technology in an educational and engaging manner.
