OpenKSK PCB Bundle

Reproduction PCBs for the Sega CD Model 1 & 1992+ Japanese MegaCD Model 1 with Sony Drive Train. Please read the listing carefully before purchasing.

The OpenKSK is a reproduction of the Sega CD Model 1's laser board for systems with Sony drive trains.

Particularly this board's later variants are known to be extremely fragile. All but the earliest boards are made of cheap, paper-like material with singled sided eyelets connected to thin traces with no teardrops. These pads are extremely easily damaged during recapping, especially if the board has any kind of pre-existing damage from water, humidity or acid leaks.

What it does:

•  Allows the clean repair of boards with damaged or missing pads, particularly for the electrolytic capacitors, avoiding bodge wires in a circuit that is quite sensitive.
• Allows a safe re-cap with extremely thick capacitor pads that will not damage easily. 
• Pairs well with Cosam's Repro Main board for a stylistic look

What it does NOT do:

• Does not fix burned out lasers 
• Does not fix dried out rails and gears 
• Does not fix issues with focus or laser power from improper tuning of the pots 
• Does not fix failed chips or other on board components such as the limit switches or motors. 
• Does not fix issues from capacitor leaks on the mainboard, which sometimes cause disk read errors instead of the drive.

Models: The Sony drive train is generally found in NTSC-U/J models, while the JVC drive train is generally found in PAL models. There are occasional exceptions for please confirm your drive model before ordering. This board is NOT compatible with JVC models.

Please note: This is a very advanced project. Significant skill in soldering and desoldering is required along with appropriate tools. Please review the documentation and/or install video carefully before purchasing to understand the project requirements. You will need to purchase a compatible donor unit, and optionally, any parts you wish to use new separately. There is no guarantee that you can make a successful build simply by purchasing this product.
