Don't forget PC-104 and PC-104+ used heavily in embedded applications.

   Well even if that many users use S100 stuff, I think it is important just to 
have it in a centralized library.
 
Perhaps it can be organized under categories, like motherboard busses and under 
that you will find footprints for:
 
1.      ISA
2.      EISA
3.      VESA
4.      IBM MicroChannel
5.      PCI
6.      PCI Express
7.      S-100
 
 
 
  Maybe we can even have a “Wizard” that will ask you for the number of pins, 
the spacing between pads, the size of the pad..etc
 
and the Wizard will automatically generate a footprint file!!

Hi! That sounds like a good idea but I am not a KiCAD developer or library 
maintainer. I'm not suggesting to build up a common parts library 
infrastructure although that would be very helpful if such a thing existed. 
www.kicadlib. org is helpful but what you are describing is much more involved. 
I suspect we've all probably "reinvented the wheel" along the way at least once 
or twice. Basically I'm just an enthusiastic amateur homebrew computer builder.

My home brew computer information is free and might be useful to others with 
similar interests. I've made several custom parts for S-100 connectors, board 
outlines, templates, and a lot of tweaks to Z80, 6809, and related 
vintage/classic computers. However it is kind of a specialty niche and is 
clearly not going to appeal to the wider KiCAD audience. S-100 stuff isn't 
exactly common these days...

I am fairly sure none of my stuff would stand up to any sort of "audit" without 
major corrections. It's just the starting point not a completed works. For 
example, I've never made a 3D model since I haven't seen a need for one. The 
S-100 bus connector footprint works just fine and I know what it is on the PCB 
enough for it to be useful. The same for Propeller DIP, SY6545, and other 
custom parts libraries. What I have would be a useful starting point for 
another interested hobbyist but not sufficient for inclusion in any sort of 
official KiCAD part distribution, IMO.

I guess I had more of a "template" approach in mind. Start with a sample board, 
rip out the parts you don't want, put in the stuff you do want, make 
adjustments, make your own board, build, test, pass it along to the next person 
kind of a deal.

I hope this clarifies my intent. If there are other home brew computer 
enthusiasts using KiCAD please let me know and I might be able to help out with 
a somewhat better starting point than completely from scratch. 

Thanks and have a nice day!
