+The name comes from a certain fictional monster with three heads. The prefix tri- is greek for three, and the Tridora-CPU
+has three stacks instead of just one like almost all other CPUs.
+It also
+has a strange mixture of features from three different eras of computing:
+- a simple instruction set without integer multiply/divide like an 8-bit CPU
+- speed is like a fast 16-bit CPU, also 16-bit instruction words
+- 32-bit word size from the 32-bit era
