Short answer is yes. Os9 may load the program anyplace in memory. Some OS's
consult a patch table which makes it look like PIC code, but its a hack,
multiplying the chances for a take the system down error. The advantages of
PIC code far outweigh any <2% loss of speed considerations when running on
either the moto or the hitachi cpu.
