Looking for Mikohn Parts

[jay]

I am looking for some Mikohn progressive parts....

Specifically I am after some Cham44 boards (also know as LED4).
I could also use a spare Mikohn gateway - these are used to convert a CON1 output to a PE+
Any spare Con1's might be a good idea too if the price is right.

I have finally after 3 years got my home casino back up to par, and I need to rebuild my large overhead sign (10 ft, ... 2rows of 8 display boards @ 16" each).
I think the power supply that I had the board on, fried and took the board with it. I had a spare and have the sign partially working (I have not dug out all the display panels).

Anyways it has left me with no spare boards and given these were built in the late 80's they are now coming up on 40 years old.....

Also would be interested in any kind of overhead sign plexys - I have one that wraps around my 36" progressive sign sitting over a bank of slot machines (double double bonus poker).

I have some mikohm parts for stand alone progressives if you are interested

I have shot you an email.

I have some Mikohn boards.  Not sure if i have what you need.  Maybe post a picture or PM me.

Here are some pictures of the equipment.

This is a CON1. Its the progressive controller - designed to link several machines together into a common progressive. You can have up to 4 levels of progressives.

You can see the two rows of white pins. Depending on the model of the CON1 there may be as many as 32 pins on the left bank. The one pictured here is a 4 machine model.

2 wires run to each slot (common ground + Coin in). As coins are inserted the progressive amount advances.

The pins on the right are for the display. Again 2 pins are used. There are 3 sets of outputs. The first is for overhead displays and the other two are for smaller displays. The output from any of them are exactly the same. I am not sure if the one for overhead displays has a higher voltage bias because its designed to run longer distance.

This second board is the Cham44 also known as a LED4 (Link Extension Device).
It takes the two wire display output from the CON1 and then outputs to the display panels connected by the ribbon cable.

The board is sitting on top of a Mikohn power supply.

The display panels are interconnected by the same style of ribbon cable and power from the power supply.
Typically you can run 4 display panels from one power supply. These things suck alot of power and get quite hot.

This is a Mikohn Gateway.

It takes the 2 wire display output from the CON1 on one side of the device.

On the other side of the device there is a 2 wire output.

On the S+ and PE+ there is a 4 pin connector on the motherboard for the progressive.
Ground/Coin-in/Data/Unused.

The Ground and Coin-in run back to the CON1 for the coin in / advance progressive.

From the 2 wire output on the gateway, you combine the ground from the gateway with the ground from the coin in and run the other gateway wire to the data pin.
This allows the progressive amount to be shown on the PE+

Lastly for completeness of this thread.
This is a Cham1 also known as a LED5

Once again it takes a 2 wire input from the CON1 and outputs via a Ribbon cable to what I believe is a 12 cell LED panel.
Mikohn uses the term meter when it refers to the LED display panels.

I have all of this, let me know if this is what you are looking for.

Hi Everyone still looking for the Mikohn Chamm44 boards.

RILaw helped me out with the LED5 boards and such.
