(MESS) APC: Fixed a few missing keys (a few are still missing though),

Browse Source 
and hooked the rtc clock, command and strobe lines up in a plausible
configuration. The status line clock now works though shows an invalid
value for year (the upd1990a didn't have a year response, so perhaps
whatever rtc is being used here is a later variant which does store a
year). The "date set" command doesn't work properly and doesn't even seem 
to poke the rtc at all. Needs further investigation. [Lord Nightmare]
