Here's a message I got that's some official low-down: You'll have a wall outlet with 4 rj45 connectors. Each connector could connect to a phone, or a 10base-T ethernet controller. You'll probably get one of the 4 connectors activated for a phone. You'll get AT LEAST one of the connectors activated for 10base-T. You MIGHT get two connectors activated for 10base-T. The issue of one/two 10base-T connectors being activated is the cost of the network hardware to support it. The proposal, which sounds like it will be funded, is to get enough network hardware to activate one 10base-T connection per room. Housing might decide to put up the money to provide the additional 10base-T connection. The 4 rj45 connectors will each be wired--each connector will have two twisted pairs. So, each room will have 8 twisted pairs run from a wiring closet. The wiring closet is where the network equiptment will be installed. This equiptment consists of 10base-T hubs and a router. The 10base-T hub is a box of electronics which can connect 12 (or so) 10base-T cables. To support more 10base-T connections per room more 10base-T hubs would be needed. The router could support however many 10base-T hubs that were installed. The wiring would already be there. If you just want to hook up one system, you'll need a 10base-T ethernet controller for that system. For pc clone type systems, you'll be able to buy one from the Computer Warehouse (the new name for the Microcomputer Service Center) for about $120.00. For your Amiga, if you get an ethernet controller that has an AUI (15 pin D connector -- I don't know what that costs) you'll need a 10base-T to AUI adaptor (about $140.00) to connect it to the rj45. If Housing decides that there will only be one active 10base-T connector, and you have some money, and you want to spend it on ethernet hardware to connect up two or more systems you can install your own 10base2 ethernet. I think you can buy a lot of these parts from Radio Shack or someplace like that. To install your own 10base2 (thinnet or cheapernet) for system you would need: a T bnc connector, and some rg58 cable with connectors on each end. This might cost $10-$40 for each system. You would also need two thinnet terminators (a connector with a resistor inside) for maybe $10 each. Then you would need a 10base2 to 10base-T repeater that costs about $400.00 -- you just need one of those. That connects to the active rj45 jack on the wall, and to your thinnet network. You could hook up 10 systems in your room this way -- but you'd end up spending some sizable cash. ------ What I want to do - is to run an FTP site off the my 5 meg Amiga 2000 with 105 Meg HD. I'd *LOVE* to run Citadel 68k (my favorite) but.. aparantly the Amiga's ethernet board dxoesn't support our 10-base-t... What do I do!!!?? I dont want to spend a fortune - I mean the board is $250 and what else is it gonna run me!??? Please please please please reply here or to my address below.. thanks!!! -- E Pluribus // Contacts: jeremym@brahms.udel.edu or jeremym@chopin.udel.edu or Unix // jeremym@freezer.acs.udel.edu -amiga clasic 2000- \\ // --->Monitor of comp.sys.amiga.emulations<--- \X/ 2001 Dalmations - My stars, its full of dogs...

No sweat dude ! It's easy ! ((-: What you need is a TP-MAU (understand a twisted pair media access unit (understand a twisted pair transciever)). What it is, is a small box that has on one side a 10base-T connector and on the other side the usual db15 AUI connector (understand 'Thick Ethernet' connector). That's what your friend calls a 10Base-T to AUI adaptor, it's simple plug and go, since the Amiga Ethernet card has both a thin and a thick connectors. Or, you wait untill CBM offers a 10Base-T Ethernet card (should be around the same price as the current one). By the way Mr Commodore, will you eventually release such a card soon ???? Believe me, this is important ! 10Base-T is gonna be big RSN (it's allready in fact). As for the end of the message, you are not concerned, since you only want to connect one machine. The problem will eventually be with your roomates, and the number of machines per room you want to hook to the net. Hope you're living with, like philosopy majors ...
