2005-

Ethernet Interface, with built in 128K EEPROM for settings, and MMC/SD card slot for mass storage.

Current status: Released. Priced £69.99.


Mass Storage for SAM files using MMC and SD cards supported with B-DOS 1.5t


Unveiled in issue 19 of Sam Revival magazine.

In Development: Port of uIP TCP/IP Stack by Adrian Brown, Ethernet driver by Simon Owen.

Re:Trinity Ethernet Interface

Just to update the preliminary information that’s in Sam Revival 19, I’ve increased the size of the EEPROM from 8K to 128K to allow for more settings storage space for ethernet applications, and a much more flexible allocation system.

Hoping the PCBs arrive in the next few days to get the first few production units built up. More info, and the first programming article is due to appear in the next issue of Sam Revival at the end of October.

Re: Trinity Ethernet Interface

Trinity is now released, priced at £69.99 + postage.

Simon Owen and Adrian Brown have had theirs for about two weeks now and are making rather rapid progress towards a completed TCP/IP stack.

Re: Trinity Ethernet Interface

Mass storage is now supported with B-DOS 1.5t, supporting MMC and SD cards up to 1GB in size with the currently released version. This will be bundled with the Trinity Ethernet Interface, as well as sent out to existing owners, and it’s also on the coverdisk with SAM Revival issue 21.

B-DOS 1.5t beta5

Just finished an extra update to the version of B-DOS for using MMC and SD cards with the Trinity. Loading from MMC / SD has been increased by 15%. Source and DOS file will be featuring in SAM Revival 23 and if any Trinity owners want it quicker drop me a line!

Also just finished the Trinity Boot ROM and code to allow the SAM to boot B-DOS from the onboard EEPROM at power on. Just awaiting some EPROM chips to arrive then i’ll make them available for Trinity owners.

Re: Trinity Ethernet Interface

A quick video on YouTube showing TCP/IP working. There’s still work to do, but things are moving…

Impressive work Colin!

Impressive work Colin!

Re: Trinity Ethernet Interface

Credit where credit’s due. I only did a few tweaks to the code for the downloading :)

A big round of applause to:

Adrian Brown - hand converting a C 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

It’s damn cool to see

It’s damn cool to see working! :-) Can’t wait to see working SAM websites and stuff! :-D

Downloading a game straight to the SAM!

Another TCP/IP demo program… downloading a game straight to the SAM!

YouTube Link

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 25.

Re: Trinity Ethernet Interface

This demo will be on the coverdisk with SAM Revival 25, along with another TCP/IP test program which will download a game directly to the SAM using the Trinity Ethernet Interface.

Re: Trinity Ethernet Interface

Thanks to the coding skills of Chris Pile, B-DOS for the Trinity now supports MMC/SD/SDHC cards up to 64GB in size!

The new B-DOS will be bundled with the Trinity from today and it will also feature on one of the coverdisks with SAM Revival 25.
