I am guessing that there is a ROM that might need replacing or possible
there is
something wrong with the battery holder? Any ideas?

I believe there are also some opto-isolators that keep the solenoid
voltage present at the flippers separated from the logic-level inputs
needed to instruct the CPU to advance the letters. Might want to check
those for gozintas -- gozoutas (i.e. voltage going into the LED side,
logic level wave-forms coming out the transistor side). --Bob

IIRC, High Speed has a second switch mounted piggy back on the flipper End Of
Stroke switches. It's separated from the EOS with a plastic leaf that has a
triangle head at the end. When the flipper fires the pawl opens the EOS and
instantly closes the logic switch. This same switch performs Lane Change (c)
on other W*ll*ams games. Remove the balls, lift the field and inspect the
flipper assblies. That second switch is probably quite disfigured. The right
flipper may have another switch that feeds power up to the top left flipper.
I can't remember off-hand, and my manual ain't handy.
It's very important to note that if the EOS leaf blade contacts the logic
switch, it feeds solenoid power into the switch matrix, so make sure those
plastic separators are in good shape!

I had and fixed this problem a month ago. The above is correct and
seems to have been my problem. The switch doesn't have to be bent very
far before it can no longer make contact.
HS has no optical switches anywhere in the flipper assembly, and the EOS
switches are driven into the switch matrix.
Problems with the lane change switches on HS are easy to ignore because
there are no rollover lanes to change. But if you can't see and hear
the engine revving noise when you hit the flippers before you launch the
ball, they're broke. (Bote that the game does this randomly before
launch too, but it does it whenever you hit the flippers if things are
working.)
The upper-right flipper isn't activated by the lower-left flipper,
either. There's a double switch on the flipper button. (Power gets
daisy chained, but the ground is handled seperately, I suppose.)
The upper flipper has only an EOS switch, no lane change switch.
I suppose it's possible that something in the ROMs is hosed but this
stuff's all on the switch matrix so that seems unlikely to me.

HS, and that's it
