"Vactrols?"</font></p>
<p><font size="4">I bought a bag full of Siliconex optos years ago,
they are all over the map in response time.</font></p>
<p><font size="4">I had tested quite a few in a very crude
breadboard setup, mostly just looking at on/off resistance
timing and off resistance and then putting them in envelopes
with details written on them. I'm sure i could do that again,
i'm just wondering if it's been done better.</font></p>
