The calculator's link voltage depends on the batteries. If the batteries
were new, the voltage would be slightly higher. The voltage is likely to
be near, but less than, 5v. If you wanted to feed a 5v signal into the
link port, that would not be a problem. Unless you had the link port set
at 0v at the time.. If you're trying to attach something like 74xx
logic/glue to the link port, it should work.
