A M6809 emulator in GoLang with Coco1/3 NitrOS9 Level1/2 personalities.

It used "sbc09" (in C) as its starting point.

It's named for OMAR, my homegrown wire-wrapped 6809 system, built in 1983 in Professor John Peatman's Microprocessor-Based Design lab at Georgia Tech.

Starting a FORTH for 6809, with "relative" pointers, for position-independant code.
