    clock
  • a simple battery backed up clock
  • only a couple of components are on the board - the ICs are a SARONIX RTC58321B and a SN7400N
  • A-Time remains active until the clock is read (by issuing the Read-RTC program from CLI or the Startup-Sequence), after that it becomes inactive and the parallel port is passed through transparently
  • without Read-RTC it will be automatically disabled when output is detected (eg. towards a printer)
  • when inactive, it's not possible to read or set the clock until the next reset or startup
  • early versions were hanging down from the parallel port, conflicting with the A1300 genlocks so later it was changed to hang upturned
