Over the summer, I created the MTS-70 app, exclusively for my dad’s vintage TRS-80 Model 1. Despite its limitations, the MTS-70 does six quirky things for my dad’s enjoyment, like chatting with Dadbot, playing Go, and previewing marine forecasts. I faced numerous challenges, from creating a custom power supply to getting the TRS-80 online using the TRS-IO card. Despite the setbacks, the project was a hit during my dad’s birthday weekend and highlighted the enduring appeal of vintage tech. The TRS-80 community remains vibrant, and I look forward to future projects connecting old and new technology.
