Re: A85: expander idea (clock)

That could be done, but it would probably need to incorporate the link port.
The calculator pings the port at startup, then we use z80 timing routines to
continue the countdown.  The calculator pings the clock every 5 minutes lets
say, unless otherwise told (like if you wanted to play a link game).
