Description

Multi purpose ethernet interface, with built in 128K EEPROM for settings, and MMC/SD card slot for mass storage being the three main features hence 'the trinity'.

Initial use of Trinity requires a floppy drive to load B-DOS or you can install a Trinity Boot ROM to allow the SAM to boot B-DOS from the onboard EEPROM at power on.

Current status: Released. Priced £79.99. Updated in November 2019 to v1.1 with purple PCB. Updated in 2021 with a red PCB.

Mass Storage for SAM files using MMC and SD cards up to 64Gb supported with B-DOS

Unveiled in SAM Revival issue 19.

A big round of applause to:

Adrian Brown - hand converting C based uIP TCP/IP stack to Z80 assembler by hand

Simon Owen - writing the Trinity Ethernet Driver for handling the comms to the ethernet controller on the Trinity

Warren Lee - original artwork

David Sanders - some fab eTracker music

Chris Pile - B-DOS enhancement to increase supported card size.

Trivia

Thanks to:

Howard Price - for letting his SAM remake of XOR become the first downloadable game for the SAM!

Adrian Brown - for the TCP/IP stack code

Simon Owen - for the Trinity Ethernet Driver

The two TCP/IP test programs will be included on the software disk with supplied with the Trinity Ethernet Interface as well as on the coverdisk with SAM Revival issue 25.
