This "Draft Version 1.0" reference claims a 10MHz clock for the
MC68000 and a 5MHz clock for the Am9513; though the original design
may have specified a 10MHz CPU, and though this speed may have been
realized in later models, schematics suggest the system's core
devices actually run at 8/4MHz (divided from a 16MHz XTAL), which
lets the 1.0 monitor ROM's Am9513 configuration generate a more
plausible baud rate.
04/12/2009 Skeleton driver.
04/04/2011 Modernised, added terminal keyboard.
