Nothing to worry about...

Need more info. What is the condition of your connectors to the CPU,

MY BH has developed an intermittant fault.I can be playing the game on
the upper or lower pf,then,it will just hang.Lose power to the
flippers,initially I though that was it-ie just losing flippers-but
checking around I see any hits on targets etc won't register.
The display stays fine-ie showing whatever the current score is.
If machine is turned off,then back on all will be fine.It may be fine
for one game,maybe 10 even,it just happens randomly.
Wondering maybe cpu is hanging??Or something else I could look for?
I have original power and driver boards,and aNi-wumpfcpu board.
Only started happening yesterday

Hi all,
Thanks all-just an update.
After closer inspection I realise previous owner had done most,but not
quite all mandatory mods.
I have now added a ground cable to theNi-wumpfboard,and replaced
pins on a connector on the cpu board.
Quite a few connectors and/or pins have clearly allready been
replaced,and a comlpete new interconnect loom assembly had been fitted
between the driver/cpu board.
I think (touch wood)you were right the connector pins seem to have
fixed it-difficult to tell with an intermittant problem I know!
It is all working fine and scoring correctly.Although I have to read
display from right most digit to left for the switch tests to be
correct to the manual.As i said all working right;maybe it's aNi-> wumpfthing?
Sys 80-a bit of a PITA,but worth it!!

Poibug - if you haven't got an answer for this yet - let me know.
Older revisions of our CPU's had DEBUG code released in early serial
number boards for production release. This code was waaay too much
overhead for the CPU to handle during long uptime, and infrequently
allow the CPU to lock-up (stop, that is - NOT lock-up coils or cause
anything to damage the game) in the main code idle loop. I believe
that serial numbers lower than 155 *can* have this problem if it
hasn't been updated. Updating the code on the board should fix this
(download it from the website - use a computer to update it).
