The obsonet reloaded

Friends, I've recently been busy with the Obsonet Reloaded project, the rereading of the first network card made for MSX. I made a version of the board so that we could use a standard Patola Plastics box (widely available down here in Brazil), made some improvements in isolation, organization of components in the PCB, footprints and with the help of Wagner Tavares, we fixed some minor problems in the TCP / IP STACK UNAPI created by the legend, Konamiman.

As always, if I used something open source and make improvements, I publish everything back on GitHub also in open source model. By the way, I always publish there everything I do... lol

All Daniel Berdugo's original work, as well as mine is licensed under CERN OHL-S (open hardware).

I also created a video (sorry it is in Portuguese) showing some cool stuff we can do with the card. The video is available on YouTube on https://www.youtube.com/watch?v=Ph_3VFheo2I. Watch there and follow the channel... I'm trying to video document all the crazy things we've been doing down here on free time.

I wrote an article in English with all the information and the step by step instructions if you want to build a cartridge from scratch here http://www.theretrohacker.com/2022/11/04/the-obsonet-cartrid...

The project's GitHub with everything you need is available in https://github.com/cristianoag/obsonet

Enjoy!

The corrections of the UNAPI TCP/IP layer are in the cartridge BIOS or on the driver side?
Would it be possible to know the nature of these corrections (in the big lines)?

Thanks for sharing it, Obsonet is one of the network devices suported by SymbOS, so you can do a lot of things with it for sure.

I don't think Obsonet is supported by SymbOS, it supports that, device for CPC and gr8net and denyonet as far as I know, since Obsonet doesn't have tcp/IP stack built in, it would be difficult to get it working nicely with SymbOS (though not impossible, but performance would probably suffer even more than on DOS)
