I doubt that. An avarage Linux/*BSD box will doubtlessly outrun this thing, regarding performance. (If you're able to lay your hands on it, which is a tale of its own). I suspect that the thing has a major part of the TCP/IP stack in hardware, which effectively means that you can't make a router of it easily. > Question: > 1) in what way is it available; can you buy it (price), build it? Honestly, I don't know. The thing I had on my desk was a gift from the appropriate company (whose name I have forgotten - I'll check that next Thursday, when I'm @work again) to a certain manufacturer of lamps in the southern part of the Netherlands.. They gave us an experimental kit, consisting of the "real" thing (some small module, carrying the microcontroller and ASIC), and an interface board (containing the UTP transceiver, MAX232's, voltage regulator...). They *intend* to be selling the thing at a low price ($10, or thereabouts). A small serach on Google gave some results. Check http://www.linuxdevices.com/articles/AT7186701822.html (Not that it is even remotely related to Linux...). Interesting detail: "According Jack Schoof, NetMedia's founder and CEO, the P89C51RD2 is so new that there are not more than fifteen of them in the US, right now. (That's probably why he wouldn't lend me his prototype SitePlayer to play with!)" The P89C51RD2 is rather old hat. I've been using the darn thing for more than 1.5 years now. > 2) what interface is available towards the rest of the world (RS232, > parallel)? RS232 (3-wire interface); and a spare I/O port (8-bits), AFAIK. It wasn't exactly my purpose to tell you that This Is The Way To Go, but it might prove to be interesting anyway. If that RealTek chip is available seperately, I see no reason why a C64 can't have an Ethernet card. A 8051 isn't exactly the worlds fast machine. (allthough the 8051RD2 clocks twice as fast, "only" having a machine clock of 6 clock cycles. (and the avarage instruction takes 2 or three machine clocks.
