About the Kinetoscope SRAM Bank Board

Kinetoscope SRAM Bank Board is an open source PCB design by joeyparrish, published on GitHub under the MIT license. It is a 2-layer board measuring 50.8 × 78.7 mm, with 39 components from 6 distinct parts.

Other key parts include the 74LVC138APW,118, SN74LVC8T245PWR and IS66WV51216EBLL-55TLI. By type, the board carries 24 capacitors, 13 ICs and 2 connectors.

It belongs with the retro computing designs in this gallery.

From the project

Kinetoscope: A Sega Genesis Video Player

The hardware is composed of several stacking boards, each of which hosts a set of subcomponents. The subcomponents are each in a subsheet, exposing hierarchical pins and buses to the parent sheet.

One of these boards includes a microcontroller with WiFi, and runs its own firmware to take commands from the Sega ROM. See firmware in the ../firmware/ folder.

The first working prototype looked like this:
