About the TRSG3Mod PCB
TRSG3Mod is an open source PCB design by Board-Folk, published on GitHub. It is a 2-layer board measuring 17.4 × 35.7 mm, with 6 components from 6 distinct parts.
Other key parts include the 2332. By type, the board carries 2 connectors, 2 resistors, 1 IC and 1 switch.
From the project
TRS-80 Model I Japanese Version
Two versions of an updated character ROM substitute board based on the original Gendon3 Mod board that uses an 2716 or 2532 EPROM to provide the character set without an original Motorola chip. They require a soldered wire connection not provided by the character ROM socket.
Both boards allow the use of a 2716 2KByte EPROM to provide a single character set to the system, or a 2532 EPROM to provide two selectable 2KByte alternative ROM images.
