We would appreciate your comments about your interest on ObsoNET, Wow, this sounds great! Is there some site with more detailed (technical) information about your product? Like: is this a full compliant TCP stack (or ar some features left out, because of, for example, memory restrictions), what is the current (test card) transfer speed and what transfer speed do you think to accomplish with the 'final' card. Does it support things like DHCP, or how do configure it. Tell us more! :))) You are mainly talking about the software. TCP stack, DHCP, it's all got to do with the software, and not as much with the hardware. In this case, Internestor (http://www.konamiman.com/msx/msx-e.html#internestor) is the most obvious choice. About ObsoNET and transfer speeds, that is depending on the software, protocols used (if they can be and are implemented efficiently), and the hardware. The hardware in this case supports buffering and block-level transfers, so it should be fairly fast, and it could be sped up even a little more if they'd implement some kind of Sunrise IDE-like data port mapping. If the protocols you're using are on the same level of complexity as the DOS2 disk routines, and the interface's hardware allows for transfer speeds just as fast (which I think it will), then you should be able achieve an odd 200kb/s with this little toy :). However, that's just a very rough estimate. But I think the minimum you can achieve is certainly 50kb/s... ~Grauw -- Ushiko-san!!

[MSX] ObsoNET: First speed test
I have performed a simple transmission speed test with the provisional BIOS of ObsoNET. The test consisted on sending one 1KByte long packet, 1 times on a loop, and measuring with the MSX timer how many time the operation took. These are the results: On R800: 31 seconds, so about 320 KByte/second. On Z80: 118 seconds, so about 85 KByte/second. Of course the real performance will be smaller since on real applications more code will be involved, especially when using TCP/IP. But this can serve as an indication of the absoulte maximum transmission speed achievable. *** XXVI MSX USERS MEETING IN BARCELONA: OCTOBER 31th 2004 *** - Konami Man - AKA Nestor Soriano (^^)v http://www.konamiman.com- [EMAIL PROTECTED] ICQ#: 18281450 Be conservative in what you send and liberal in what you receive - ___ MSX mailing list ([EMAIL PROTECTED]) Info page: http://lists.stack.nl/mailman/listinfo/msx

A good browser would be really cool, and I think there would be quite a demand once our MSX is connected to the internet directly. Me and Laurens Holst have been toying with exactly that idea for a long while already... I'm definitely willing to put aside some of my other MSX projects for a while to code this thing.
