Perhaps a less... bulky method (no monitor required) might be to have an
LED/LCD dot matrix display connected to the parallel port and output the
number to that in the script that does the database entry?

But, for a monitor it's simple.
You don't even need a login prompt, that could be removed by editing
/etc/inittab.
Just output to /dev/tty0. The permissions on it would need to be changed for
non-root to write to it, but...

echo "1" > /dev/tty0
