Simulate dice roll mechanics from the comfort of your vintage Tandy TRS-80 Model 100/102/200 ("Model T") laptop! Roll any die from d1 to d4200 (why not, you know you want to!) or use one of the built-in systems. Designed to pass around your table, the Model T Dice Box brings a retro new dimension to any game night! Dice Box supports a variety of popular RPG systems and dice mechanics including standard dice expressions (A+*dX+-*B+-L:H), exploding dice pools, full Continuum support (yes, that really is the best time-travel RPG you might never play), and one-off rolls like Traveller's d66. See the feature list for more RPG systems available! This project includes the compact source code (.DO), the tokenized BASIC (.BA), and a REX image (.BY). Dice Box needs around 1KB memory while running and the tokenized BASIC file is ~12KB. And check out the video! Fun fun fun!
