With a processor the best way to adjust the output voltage is via a PWM (Or
a DAC if you want to get fancy).
Since a voltage into the adjustment resistor results in a linear change in
current (The other side of the resistor is maintained at a constant 1.24V)
in the feedback network, the output
Hi Jens,
At the risk of stating the bleeding obvious... Have you asked John Taylor
directly? He is a member of this group, and may well stop by shortly
anyway, but if not there's a contact route through his website (

The best I can suggest is to infer the pinout by looking at the placement
of the pins on the back-side in relation to the various cathodes visible
from the front. I did this with a similar display (SP-151). The anodes are
copper-colored electrodes; everything else is a cathode. The segment

Well, it seems that was prophetic! At least at the time I was typing it,
anyway
Ebay auction just ended for a Burroughs tube which was likely a 7094, based
on the size. It's gonna be really hard to find 3 more of these for a clock.
Amazing what people are paying for these
I have this clock and have had it for about 3 months now:

Tonight I was moving it around and I noticed that the left side
