Notes:
- %1 - Unpopulated position for D4701 IC
%2 - Unpopulated position for MSM6253RS IC
%3 - Unpopulated position for MSM6253RS IC
- For games other than Hot Rod, ICs other than LS139 and one uPD4701A are not
populated. Hot Rod doesn't seem to use the second MSM6253 (whose four inputs
are labeled "BLAKE" on the schematics), but has it populated anyway.
- CN1 is shown for completeness, it's actually underneath the I/O PCB.
