Last year for Hands On, I gutted a defunct TRS-80 Model 100. The goal was to upgrade its 24 kilobytes of RAM and 2.4-mega-hertz, 8-bit CPU but keep the notebook computer's lovely keyboard and LCD screen. That article was almost entirely about figuring out how to drive its squirrely 1980s-era LCD screen. I left the rest, as they say, as an exercise for the reader. After all, sending a stream of data from a new CPU to the Arduino Mega controlling the screen would be a trivial exercise, right?
