Bingo Pinballs
_ Bally
Continental KDU _
OK, I
don’t even know what to say here`…This is a complete Mess
Back in 2005, I was talking to Oliver about
building a KDU (program box) for one of the Bingo
Here is what I have`…Oliver never
mentions if his device works`..and it
doesn’t look like I asked`

Hi Danny,
I have the manual; this unit is used for the
self test functions. I analyze the existing schematic and made a try. In
the schematic you see the strobe and return lines. The KDU units is quite
similar to a bally 6803 keypad, I scanned almost the entire manual. Do you
want it?
Greetings Oliver
This is the picture of the KDU out of the
Bally manual and I do not think anyone actually has one`
Oliver wrote in to share that we tried to build one from scratch`…Now
this is very Cool
_ Bill-of-Material (BOM) and Wiring Detail _
16 * 1n4004
16 * pushbuttons
7 * 430 ohm resistor
3 * 7 segment-Led (HDSP-5503)
I first used 4 HDSP-5503, but the bally kdu has
only 3.
Here is the
wiring:
Connector
Pin 1 ->
430 ohm -> Segment (1-3) pin 7
Pin 2 ->
430 ohm -> Segment (1-3) pin 6
Pin 3 ->
430 ohm -> Segment (1-3) pin 4
Pin 4 ->
430 ohm -> Segment (1-3) pin 2
Pin 5 ->
430 ohm -> Segment (1-3) pin 1
Pin 6 ->
430 ohm -> Segment (1-3) pin 9
Pin 7 ->
430 ohm -> Segment (1-3) pin 10
Pin 20
->
Segment 3 (rightmost) pin 8, 3
Pin 13
->
Segment 2 (middle)
pin 8, 3
Pin 14
->
Segment 1 (leftmost) pin 8,
3

So, why does Oliver
callout (2) connectors...?
In my original post
for this I mention that I might have had a schematic`…I still cannot
locate it`…I think it might be zipped1
_ Now, I also
posted this picture with the detail from Oliver`…Why is
anyone’s Guess _
What is Cool
here is that this looks to be a Controller that is used to “add
games” to the Bingo
The same
concept of Tel. In and Tel. Out that the Belgium boys have for nearly all
of their early machines`
So, none of the machines
here in America were this advanced, the bars, taverns, and clubs
weren’t wired for this`
Clearly Bally designed this
contraption for the “offshore markets” -or- singular-market -
Belgium..?

stuff from my archives I don’t think I ever posted _
