[sdiy] More beginners questions

[James Patchell]

The N designates the package....in this case, a plastic DIP (good for DIY)....

As far as a scope, you are going to get a lot of different answers to 
that.  At the moment, for my synth stuff, I use a cheap 20MHz dual trace 
scope, in general.  This scope doesn't lie...it will always report on the 
screen exactly what is there.  I also have a few digital scopes....and 
while they are much nicer scopes, they tend to lie a lot, and I don't like 
liars.  But, they are handy when I need a picture off the screen.  You can 
get a brand new 20MHz scope for about $400, give or take.  Used ones you 
might find cheaper.  If you find a working Tek 465B for cheap, like say 
$500, and you are sure it really works, get that.
