Hiya--
I've just taken my Black Hole and Haunted House out of a 25 year "mothball" state.
HH works BEAUTIFULLY-- No issues... And it has allowed me to swap Display units from one machine to another to determine that...
BH has a Display "Segment" problem in the STATUS Display unit, and Im gonna need to replace a/the chips on the Display Board.
Are the UDN6118s and 7432 Chips Soldered into the board or can they be removed without soldering?
Can the chips be removed with careful prying with a screwdriver or is there a special tool designed to remove the chip?
The machines are located in a summer home, and I realized that I can't just look at the boards TODAY and determine if the chips have sockets.
Also-
How many balls does the BH take?
The trough allows 5 balls-- but I think it only uses 3, yes?
THANKS.
