I’m writing it in m6809 assembly language. At present I have a simple start for a linked list editor. As I see it my system will have a 60k linked list partially compiled Urbane Basic file. That will free up 30k for low level graphics and data along with the 32k for super high level graphics. If I get that done I might jump into Toolshed.
I am going to try to get rid of the middle compile phase and have a program that translates an urbane program directly into an executable.
