About the MegaCD-Connect-BD-Remake PCB
MegaCD-Connect-BD-Remake is an open source PCB design by Board-Folk, published on GitHub under the CC0-1.0 license. It is a 2-layer board measuring 98 × 44 mm, with 17 components from 9 distinct parts.
Other key parts include the GAL22V10, 74HC374, 74ACT10 and 74HC245. By type, the board carries 6 ICs, 6 capacitors, 3 connectors and 2 resistors.
From the project
A Remake of the MegaCD Connect BD Logic Board, Targeting the 315-5477 (MCE V1) MegaCD
It is to replace the 837-8327-01 IC BD MEGA-CD CONNECT BD with a failed ASIC to the older Logic version of the board that has the Peel IC.
The board is not a clone, rather a remake as i do not have access to an original logic board version to do an exact replica of traces.
* The Gerbers have been created using the recommendations from JLCPCB.
* This board uses a GAL22V10 to achieve the same logic functions as the Peel IC. Jed file is provided. Use a MiniPro to write the Jed file to the GAL Chip.
