Mod Kits for Sega Master System

All my mod kits are hand made in the UK by me from a combination of my own PCB designs and open source PCBs and software. All my mod kits are using high quality, branded components from large distributors. Any exceptions to this will be noted in the individual product pages under the credits tab.

Most kits offer price reductions for multiple quantities making them some of the best deals in the world for mod kits. They are mostly made to order and occasionally in small batches so if something is out of stock, drop me a message. I can get most parts within a few days and would be happy to help.
