I think the assembler was by TDL. A very expensive linker was used that allowed code to be put in ROM's in dirrefent address spaces. Development was done on my home S100 Z80 system and debugging was done on a tektronix box. The combined breadboard, in-circuit-emulator and deveolpment computer setup took up most of a 4 foot by 8 foot sheet of plywood and another smaller desk. The code was developed in the fall of 1981 to help Stern use up the remaining "Berzerk" boards. I did they game on an advance toward royalties. After the game was in production, they didn't pay me the royalties and I had to retain a lawyer to collect anything at all. That process took most of 1982 and cost me 10% of all monies collected.
