Sounds awesome, can you post some pictures - screen-shots and HW?
I've plugged the HW here before:
there were no DIP .syms available so i created some with tragesym (there
are probably better ways to do that. please name them! :)
my version of tragesym did not cope well with empty pinlabels.
patch attached.

Hey all,
I am just finishing up a busy semester (last of six exams
is tomorrow) and am available to work on pcb again for the
next little while.
According to my git branch, last I worked I was playing
with converting pcb to use nanometers as its base unit.
We had a long discussion about this
I'm currently in the middle of a largish project, involving several
hundred elements and some 1,500 connections, still using a rather older
version of PCB (20080202) -- so far, it served me well.
It so happens that on several occasions, I changed the footprint of
several dozen components at once
Nanometers is the desired units. Yes, you're limited by default to a
seven foot wide board on 32-bit systems. Oh well, use a 64-bit type
for something that huge, if you can find a fab that can make it :-)
No, no real progress lately. If you want to help, the most important
thing you can do is
I can't help but wonder if there's a better way to do this?
Update to at least pcb-20100929 and use File-Import instead of
gsch2pcb. It can bulk-update footprints without moving the element or
its refdes.

in?
Mostly just stuff preparing for PCB+GL, iterating

1. I am bumping up against the MAX_* constants, specifically
MAX_GRID, but they're all too small now. Nanometers are
much smaller than 1/100 mils. Why are these there and what
can I do about them?
Most of the limits are artificial. See if they can be removed.

Does anybody have a nice and simple zener diode model they

have you tried gnucap?
You will need the spice-diode
