Not a whole lot of PhoneNet, IIRC, before we moved to PhoneNet works through the mini-DIN9 connection, using one of those gray connector boxes... so we may actually have been connected through PhoneNet during those beginning years. The reason I say this is because buying long serial cables and 3-port mini-DIN9 boxes would have been much more expensive than simply using PhoneNet adapters and a lot of cheap 4-conductor phone lines... not that that means anything. =) I don't actually recall, though, whether we used PhoneNet or actual serial cables, since that was before we got the PowerMacs (i.e. before I was wholly active in the maintenance); once those came in, we began ethernetting the entire place (and I became active in maintenance). > 10bT. In 1993, when we had The One Mac That Was Connected To The > Internet, there was a little 10b2 floating around as well. Actually, we had 10B2 the entire time the SE/30s were around, IIRC. Since the ethernet on those things was basically an afterthought (since nobody ever intended them to have it), it was only 10B2 (or in our lab, anyway). Of course, the 10B2 connections were ONLY on the SE/30s... the PowerMacs all used a 10BT network through AAUI->10BT connectors, before Apple started making 10BT connectors standard. One thing to note: one of the primary reasons the SE/30s became ethernetted (through 10B2) was because the LocalTalk->Ethernet bridge we originally installed (to link the LocalTalk SE/30 network to the 10BT PowerMac network) was notoriously unreliable, and dropped connections pretty often. After installing the 10B2 daisy-chain network (connected to the main hub [was it a switch?] through the ONE coax port), everything worked fine. =) > dot-matrix ImageWriters (GRRRNNNK! GRRRNNK!) for code listings). Argh, man, I remember those things. Yeah, we got rid of them once the 10B2 was installed. Laters. =) --- Amir
