I managed to get a connector (a grad student here at CMU managed to get me
some header pins which seem to work... however now when I hooked up the
LUCAS board, it didn't work-> when powered the power light didn't flash,
the screen stayed black and the song didn't play... I'm going to check over
all the connections, but they look good... a strange thing is that the
resistance from +5V to GND is 529ohms (I believe that the resistance should
have been around 270), I've checked all the orientations of the chips and the
polarity of the of the tant. caps, about the only thing I'm kind of wondering
is the orientation of the SIPs (I aligned the mark on the sips with the
silk screen's "1"s so I should think that's the correct orientation...)
Do the U9 varients cause it to do aboslutly nothing?   How about bad grounding,
I'll try grounding the amiga's PALs, but somehow I've got a feeling that the
problem lies somewhere on the board it self...
