Thank you all for the suggestions.  The BDI was simply too
 much for the school to spend on a small group of people.
  I did however contact Macraigor Systems and explain my
 situation.  They have donated a wiggler so it looks like
 I'm in business, thanks to Macraigor!

Haven't quite decided on the ROM exactly, still waiting on
 samples from AMD but a regular EPROM sounds like good idea
 for now.

  Hopefully the wirewrap can handle this.

It is starting to sound like I'm really going to need luck,
 so thanks.
