I picked up a High Speed pinball for $100 a couple years ago. It seems to
work
fine except for when you get a high score on the game. When it comes time to
enter your initials no letters appear. It is waiting for you to use the
flippers to
change the letters but no letters appear. You can hit the start button to
advance
to the next letter in the initials but no letters will appear anywhere.

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

Most flipper buttons have several contacts stacked up underneath them that
do different things. Next time you're playing a machine with more than two
flippers, try hitting the buttons really slowly. Odds are one of the
flippers on a side that has multiple flippers will activate first. It's
possible that the contacts that control the high score initials are screwed
up, but the contacts that actually make the flippers flip are not.

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

You got a high score on the game? See what happens if you wait and enter nothing
i know street fighter II will put up Q as your initial if you do this.

Greg,
My first suggestion is to reinitialize the cpu by selecting the install
factory audits
in service mode. If this doesn't work you may be right about the ROM IC'S.
Also make sure the AA batteries are in good shape & no leakage from old
batteries got on the main board.

Greg,

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

Thanks everyone for the help. I will try to get to it this weekend to see if
it fixes
the problem. I'll post again if not. You guys are lot more help than the
rgvac guys.
Don't hold it against me. I am a video man at heart but I love pinball too.
You guys
are starting to sway me away from the dark side!
