Re: Asteroids ROMs and PCB revisions?

I am slowly scanning in my revision 7 schematics-huge, eh?- and they have a
list of the various versions and the memory used....goes up and includes 5/6...

Someone volunteered to paste them together when I get them all in. I have
one side of page two done so far, the differences are in RED, so I have to
do them in colour mode...a bit bigger as a result...
