Thanks to Steve Korn, LABROLZ looks like this now.
Only different in the right "border", which now instead of containing
images of a Whale, a Fox, a gourd, a maggot, and a capitol city;
it now has useful circuitry for a 5 channel stereo mixer!
so all the outputs of the LABROLZ can be brought together
i will be hand-assembling this border, since it is the border that the machine assembler uses to grasp the board and no surface mount can go here. thus it is good ole through-hole, just a little bit. always gotta slog through improvements even if you think your done!
