- 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.
