[ Ah, what a delightful opportunity! How so many of us have awaited this, with relish! ] I'm sorry sir, but your silicon is TOO foul. The beauty and the elegance of OS-9 rests on the fact that all code is completely dynamically relocatable. Modules can be loaded anywhere, at any time without relinking and without MMU hardware. This is possible with 680x0 chips, but not with the 808x, at any rate. (although, on second thought, it may be possible with the 80[23]86 ... you could load the segment registers with the module base address ... ah, but isn't it true that OS-9 processes don't even KNOW where they reside?) -- Reply-to: motcid!mellman@uunet.uu.net
