It's still online here: Marina - The IP stack for Apple II

The web site is now at https://macgui.com/marina/

What happened? I never completed the TCP, and I moved on to other projects. :-/ I learned 68000 in 2019 and haven't looked back since.

Lead occurs naturally in ground water and all living things have been ingesting water with trace amounts of lead in it for millennia. At the risk of being Captain Obvious, it’s likely evolution has caused organisms to adapt to and tolerate lead content as a matter of survival. There's also trace ...

This seems to be a theme with ChatGPT. It's pretty good with concepts, but falls down on specific technical details.
That's because it can't invent anything new that it hasn't seen already, and it doesn't understand anything. All it does is remix text that it has come across on the Internet ...

I have an army of Apple computers. Perhaps I could help out. I will ping them and see what they need.

Thanks!

As far as testing goes, just download the boot disk image , put it on your real Apple IIe or IIc or IIgs (not emulator) and report back what happens when you try the different command ...

June 2016 edition is out today. Adds several improvements to ICMP support, most notably, Marina now replies to pings!

I'm assuming that to be the hard part. Populating the board and finding a decent power supply, case and keyboard shouldn't be a huge deal. I wonder if assembling and selling them for a small profit could get a person into some legal trouble?

Unlikely. All of Apple's patents from that era have ...

It's going to use the $Cx page slot I/O addresses for Apple II, but other than that, I don't think he'll be using any special tricks unique to the Apple IIgs.

The IP65 project has drivers for the W5100. One is in C, the other 6502 assembly.

I'm writing my own of course.

I would certainly be interested in the W5100 implementation. I've looked at including that particular device into another project, and would be interested in hearing of any problems and how it compares to using the 8900.
I could talk your ear off on that score. I beta tested and wrote the manual ...

Probably so. I'm not using any special features to the Apple II, such as bankswitching, or ROM routines, in the core part of the stack. The network driver would of course need to be changed, but I'd imagine that the thing could be ported to another system probably with less than a week's worth of ...

First, a super short intro on me: I've been an Apple II user since 2004, and I started learning 6502 assembly language in 2010, which not coincidentally is when I joined this forum. :) My last project was a multitasking system called the Mouse Multitasking Demo in 2014, and the project that I'm now ...

Yeah, I've been lurking on this forum for the past 5 years, now I finally speak up. I'll see about posting a topic on it soon. It's presented a number of interesting challenges, and I'm by no means an expert 6502 programmer, but I've learned a lot!

A few thousands, writing a TCP/IP stack for the Apple II called Marina. Started in February this year, so it's not quite a year old. No TCP yet, but it does UDP just fine and has a Berkeley Sockets API. No real apps other than a DHCP client and a DNS resolver.
