I think the contents would be disappointing, and prob'ly not worth
breaking them open. They are glued. I could prob'ly cut the glue joint
and pry one open, but it would be much more fun to use a LARGE mallet ot
open it.
I have two here.
Most here could design something as good in as long as it takes my to type
this, and I'm sure that Tony could build one faster than that.
The first one is model SC817. It has three red LEDs (labelled M, T, and
D) and one slide switch (unmarked).
The other one is model SC817. (just so we know which one is which)
It has 5 LEDs and two switches. The first 3 LEDs and switch are the same
as on model SC817. But, on this one (model SC817), there are two more
LEDs and a 3 throw slide switch.
They obviously
do not work anywhere near as well as a conscious human
being with an LED tester and a breakout box.
I think it's always the case that
a clueful person armed with test gear
will beat a simple 'automatic' device...
