I don't know if the owner of the site is here, but I was interested in a TTL machine that could run a tcp/ip stack, and what sort of design it was. Since being in a slash dot posting, the web site was unreachable, so I decided to hunt for it on archive.org. The site was last archived in sept 2004 and doesnt have what sounds like the slashdot article talked about, but did have a webring link at the bottom. The only other member of the webring is here http://members.iinet.net.au/~daveb/simplex/simplex.html and is about a computer built 20 years ago by Dave Brooks', and has some interesting references to old machines in it, besides being also composed of 7400 series ttl. This exercise pointed to an os, ported to run on the commodore 64, pico]os, as well as the tiny tcp stack this article referenced. I am interested in these, since these efforts would make possible some bridges into the current technology by other than rs232 ports, and allow for such things as having remote access to ancient media, if possible, and so forth, on modern systems. I am lucky that I concentrated on saving and preserving 9 track 1/2 inch tapes for all I did, and have already read them. A lot of what people did though is not on such nice media. Jim
