Defender uses two 6809 CPUs - one just for

everything else.
Williams Joust is more complicated and uses four
6809s.
nope..
Defender and Joust both have a 6809 and a 6808 for sound

My goof .. just 2 CPUs on the Joust. But I had to open the cabinet and
count for myself. :-)
www.klov.com has schematics posted for the Joust in PDF format if
anybody is interested. A bit hard to read, but very nice to find online
anyway.
