Apple is doing a binary-compiler for its new line of PowerPC Macs. It
takes in existing 680x0 code and translate opcodes for the PowerPC chip.


Can anyone tell me if this is logical, or right approach? Seems to be a
great idea. Why hasn't anyone thought of it before?

[So long as the underlying datatypes are the same, this can be a very
effective technique. HP apparently uses it to run HP 3000 binaries on the
new Spectrum RISC machines, IBM used it to simulate the RT PC on 370s, and
several packages use it to run IBM PC binaries on workstations. -John]
