The COLE-2 is, as its name implies, the next evolution of the COLE-1 SBC. It is a modest upgrade, the main change being that it uses a 65816 instead of a 6502 CPU, and has considerably more RAM.
I have tried to keep this as retro as possible but there are some usages of more modern hardware in the interest of robustness and ease of interfacing to modern peripherals (ie PS/2 keyboards, VGA monitors, etc).
