I always wondered what computer was faster, the Radio Shack Color Computer with its fancy 6809 or the TRS-80 Model 4 with the proven Z80 processor. So i tested the Coco 3 vs. the Model 4 in "Model III Mode", which means 2MHz clock and 64x16 text screen.
In this video I run a few tests using the built-in BASIC languages that are in the ROMs for both machines.
