I had trouble setting the clock on this system,
maybe this is
the reason.
If the RT-11 "TIME" command isn't incrementing, that has nothing to
do with the TCU - it's an indication that the line time clock (60Hz
for us) interrupt is somehow disabled.
With the board in, does it respond at its standard addresses of
160770 - 160776? If so, then it's installed in the right sort
of system.
You ought to see the value at 160774 incrementing once per second
if the clock is indeed ticking.
