* '''PLEASE NOTE: The schematics and files have a few errors:'''
** MC6850 pin 7 (/IRQ output, in v1-v3) is connected to Vcc, but should be left unconnected.
** The signal marked 153.8MHz (in v3) is, of course, 153.8kHz (4MHz/13/2).
** The photo seems to show v1 and uses 1.8432MHz crystal, whilst schematic v1 uses 10MHz (?)
