Added a systime implementation by Stefan Haubenthal with a few changes. The routine reads the TOD clock of CIA1 on the C64 and C128. Since systime was a dummy routine common for all CBMs before, this change adds an individual dummy routine for all other CBM systems. CBM510/610 do also have a TOD clock, so a similar function as in the C64 could be used ...
