Re: newbie.

Hello Fellow Newbie:

Great topic. I always suggest a good electronics book. Art of
Electronics is my fav.

Search / Browse for OPTO Isolators, Parallel Port Break Outs,
Buffering, Diodes, Fuses. Also I suggest you get acquainted with
using capacitors to dampen noise. I'm no expert but noise and RF
bleed is a topic that pops up here quite a bit from what I have seen.

Then you are going to have to decide if you really need 47 fuses and
diodes behind 94 opto isolators all over the place or not. It's a
cost, hassel, time, risk, warm fuzzy trade off right? Right.

There are a lot of things in the file and photo archives
