Title: MK1 connector question
Post by: anunaki on December 30, 2012, 12:18:18 AM

Hi,

I got myself a MK1 boardset that I want to put in my MK2 cab. The only thing is I only got the boards without the cables.

With cables it looks like this:

I know I need a 20 pin ribbon cable with connectors and I know where to buy them.

But I also need a couple of molex cables and a 50k Ohm potmeter:

Connector J2 (CPU Board) to Connectors P6 and P7 (Sound Board)

Use Molex 8 Pin 0.156" Header for Connector J2
Use Molex 6 Pin 0.156" Header for Connector P6
Use Molex 4 Pin 0.156" Header for Connector P7

Connector J2 (CPU Board)

I looked around all kind of internet shops, but I can't figure out which cables/ connectors I need.

I hope you guys can help me with this. What is the name of these cables/ connectors, there seem to be tons of different molex cables/ connectors.
