Tatung Einstein TC01 Silicon Disk 256kb circuit board- Gerber file

Hardware
October 25, 2025

Having an original Tatung Silicon Disk 256KB unit sitting neglected and gathering dust, I knew that there would be Einstein enthusiasts who would jump at the opportunity to own such a piece of hardware. The problem, of course, is that very few of these units were ever produced.

When this website project first began, I reached out to several programmers and coders for help, but without much success. Eventually, however, I came across individuals who were willing to assist in different ways, offering skills other than coding.

One such person was a gentleman based in Wales, whose hobby is reverse-engineering circuit boards and creating Gerber files. For those unfamiliar, a Gerber file is essentially the blueprint for a printed circuit board (PCB). It tells the manufacturer exactly where the copper traces, drill holes, and component placements need to be for each layer of the board.

I provided him with a series of clear photographs of the original bare Silicon Disk 256KB board, and he began the process of recreating it digitally. It took some time and patience, but he successfully converted the board design into a complete Gerber file. This marks an important first step.

Please keep an eye on the TatungBytes guide section—we will soon be making the Gerber file for the Tatung Silicon Disk 256KB board available for download, along with images and a full list of the required chips, resistors, and other components. This will allow anyone to build their own Silicon Disk 256KB upgrade board and help keep the Einstein community alive and thriving

I grew up with early access to the Tatung Einstein thanks to my stepfather’s work at Decca/Tatung. While friends had ZX Spectrums and C64s, our family proudly used a TC01. Years later I rediscovered it—alongside the Tatung 256—and saw the potential these machines still hold. This site is dedicated to keeping the Einstein alive: building tools, sharing knowledge, and inspiring new coders to explore BASIC and beyond.
