Hi,
I’ve been building the 8094 models recently with my 8485 (and spares.) Then I
realized that the 8094’s original plotter model really sucks: you can’t really
memorize a pattern to let the machine write for you since the pen needs to be
lifted and lowered manually (the 8094 only came with 2 motors). So I installed
the 3rd motor from set 8485.
The only challenge really was to gear down that fast 9V motor substantially in
that cramped space.
I wanted to limit myself mostly to bricks coming from set 8485 or 8094. In the
end the only extra parts needed were a few 8 tooth gears and a weigh brick on
the other end of the writing rack.
The “LEGO” sequence was completely memorized in the control center.
Unfortunately, I couldn’t get it to memorize anything longer. The control center
simply stops recording after a while. Anybody knows how to get around that?
(The yellow spot at the bottom of the glass is what’s left of the banana/orange
juice, for the curious).
After moderation:

Then I browsed Brickshelf and found someone who already did something similar
except he used a tiny micromotor (which doesn’t come in the either of the
Control Center sets.)
