Bingo Pinballs

 

 

 

 

 

A long long time ago, and I cannot at all remember why, I was talking to Olvier about building a KDU

(program box) for one of the bingos……. Here is what I have on file:

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?

Hello,

 

Greetings Oliver, I am trying to learn more about the solid-state bingos machines and

would like to know more about this KDU device.

 

What is it used for?

 

How did you know how to build it?

 

Thank you,

 

Danny

The following KDU (keyboard display unit) was missing for the bingo:



I built one from scratch:

I used the following material:
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

(pages 11=19, 30, 33, 35, and 36 (key) for schematic details) – It looks like the KDU programs by pulling line “low” to the “return” – To “ground” potential)
