- Instructions:
-
- When you open the C64 (normally 3 screws) you will see how the keyboard
- is plugged into the motherboard. There is a 20 pin ribbon type plug that
- goes into a male fitting on the board with 19 pins (missing one is a key
- to prevent plugging in the keyboard backwards). Carefully unplug that
- plug (lift at the ends and gently rock as you lift). Solder the straight
- lead header (1) to the flat flex cable (3) (both will have the same
- spacing). Solder the other end of the flat flex cable (3) to a 25 pin
- female connector (5). The straight header (1) plugs into the female plug
- on the keyboard connector (you will need to cut or bend pin number 2 for
- it to fit). This will give you a 25 pin D-sub Female connector for the
- keyboard. The keyboard assembly is ready to put back in to the computer
- case (be sure to remove the computer board first and decide where to put
- it.) You have several choices as to where you would like the 25 pin
- female connector to exit the case (it has lots of holes).
-
- Now, take the Flat cable assembly (2) and solder the other 25 pin female
- connector (5) to it. BE SURE THAT THE PINS ON THE TWO 25 pin D-sub
- connectors will match (the 25 pin connectors I have seen are numbered).
- Plug the flat cable asssembly into the motherboard and the computer
- portion is ready to install in your case (I used an old C64 case for
- this). You can put it most anywhere. Build one, use an old IBM tower,
- whatever. Again, you have some choices to make on where the 25 pin D-sub
- will exit, but less than the keyboard as the cable is only 6" long.
-
- I did not mention the little power indicator light. You will have 5 extra
- leads on the D-sub if you want to connect the light. Having the light
- come on is a nice touch. You can just solder a couple of wires from the
- motherboard to do this.
-
- For joysticks and mice you will need two 9 pin D-sub cables. The cheapest
- are Sega joystick extention cables. The 9 pin cables are common as dirt,
- so you will have no problem finding what you want. (Radio Shack, etc.)
-
- You also may not want 2 meters of cord between you keyboard and computer,
- so you can look for the length you want (male on both ends). I have a
- rig with 2 cables connected to a total of 10 feet (great for games!)
-
- If I ever get a case designed, I will offer a "kit" for those that don't
- have time to solder about 60 connections. I'm open to ideas on how to
- improve this, and what to use for inexpensive cases that would allow
- access to CMD add ons, like the Super CPU and RamLinks.
-
- The main reason for this design is to make using the C64 easier by
- separating the computer and keyboard (not a new idea). LoadStar has
- the same thing in the issue #140 with simple ribbon cable. My design,
- just to toot my SID chip, is much more flexable and LOOKS better too.
-
- I'd love e-mail from those that complete this project (CINDY.S).
- Let me know how it goes.

-
- Note: I assume no responsiblity for your work on this project,
- do this at your own risk!
- Remove power before opening your computer case.
