It has a clock chip at 0x200b8000 from where it reads current time,
similar to a PC.
The console mailbox is also in that chip.

How does a real MicroVAX II preserve its time across boots?
How is this implemented in simh MicroVAX II? i.e. what virtual device
should I attach to a file so that the time is preserved in VMS?
My configuration (below) does not preserve the time (VMS V7.3 fully
patched)
Thanks,
