That sounds like it was the same thing. It's foot-operated, so both hands
are free to position the PCB. A clamping lever comes down before the drill
comes up, so the PCB is held securely. The magnification of the pad on the
screen is quite high (it looks about 10 cm across), so it is quite easy to
use, even if one doesn't have good eyesight.
