GRiD laptops were famous for their orange plasma displays, being one of the first laptops period, and being featured in the film Aliens.

Their unique, rugged cases make ideal candidates for conversions to more modern internal hardware, which is what YouTuber SimonsVids accomplished masterfully, with the help of a Raspberry Pi, a couple of Teensy LCs, and the assistance of PJRC forum member thedalles77.

In order to preserve the original keyboard and unique IsoPoint roller bar mouse, thedalles77 wrote custom sketches for each, based on the larger How to Make a USB Laptop Keyboard Controller project. The associated GitHub repo also contains a detailed write-up on the challenges faced, as well as wiring info and aforementioned sketches. The finished product can be seen in all its glory in the video below.
