About the MSX-Mega-Adapter PCB
MSX-Mega-Adapter is an open source PCB design by tebl, published on GitHub under the CERN-OHL-1.2 license. It is a 2-layer board measuring 30.5 × 31.8 mm, with 4 components from 3 distinct parts.
Other key parts include the 74HCT04. By type, the board carries 2 diodes, 1 IC and 1 capacitor.
It belongs with the retro computing designs in this gallery.
From the project
Adapter so that Sega Mega Drive (Sega Genesis in North America) gamepads can safely be used with the MSX line of computers.
With the equipment sorted, let's take a step back and focus on what's important in this day and age - shopping. Head on over to the BOM-section for some basuc information on what you need, with sites such as ebay, AliExpress, Wish etc you'll mostly need to treat these as a starting point for what to put into the search engine. By checking out the gallery images, you should be able to discern which you'll need. Considering the delivery times to expect from China, I usually order one of each when in doubt - it should be cheap enough and I'll find a use for them sooner or later.
