okay... That's a success.... i found some crimpers and some ends...
Got it to a prompt... gotta love that...
next step is to get angband running.  :)
(http://thangorodrim.angband.org)
:)

now... could you send me a copy of that kernel?
I'm going to make a *very* in depth howto/faq today....
I'll probably put the faq on cvs and allow it to be a multiple person
thing.  :)  I want it to be very very good.  :)

The last thing we need is to loose support due to frustration.

I plan on making the faq answer all the basic dreamcast/netbsd quirks, as
well as explaination as to why it's diskless and various "can we do this?"
q&A's ... like "boot off VMS?"  :)
