I picked up a wood box LDS modem many years ago at
the FootHill Swap meet. I hope nobody harbors a
grudge but this was before I was a serious collector;
I bought it for the box and gutted it
(would never do that today).
Anyway, as far as I can remember the thing had No IC's
in it. It was all discrete components and dozen(s) of
thimble sized things in it that I assumed were tuned
inductors.
Does this sound right? A Modem of completely analog
devices?
