- Implemented support for the Orthogonal extension into
both the assembler, and the emulator. I finally figured out how I could get support for the Ortho extension implemented into the old assembler. The only reason for doing this, is to buy me some while I start work on the new assembler, and to help me get an idea for how to do the same in the new assembler.
