I grew up in the 80’s with the computers mentioned on this page. I have been collecting them ever since, and I have always been interested in how they work and the circuitry behind them. Because of this I tried to make modifications for these computers. I bought a 3D printer so I could print my own cases and parts for the mods. When I found out that there are a lot of other people looking for these mods, but don't have the tools too make these, I started making these and selling them on Ebay. I started with a single flash rom, but today this has turned into a small shop with several mods and with many more on the drawing board.
