There exists a program, to be named MICROS, which is currently waiting to
be restored from DART tapes.  This program is a cross assembler for
various microprocessors, including the Z80, 8080, 6800, and 6500
microprocessors.  This is a real assembler, not a set of FAIL macros.
More news when this utility is up.  Sugestions and comments to ROB.
