In the '90s I worked in a warehouse where some of the guys had bought old model 100s for cheap and had programmed an inventory system. The 100 was the perfect size to sit on the console of the forklift and you would record where you were placing or retrieving pallets of inventory. At the end of the day you could sync the updates from one machine to the next over serial ports. For being so computationally limited they are surprisingly capable machines. The extra long battery life made this application possible. In spite of being warehouse workers they were a very smart bunch. There were several other things they had automated as well. I was young at the time and was only interested in video game, so never picked up programming until later.
