I've got three of their FA310 adapters and a 4-port FE104 hub for my 100BTx segment. It's cheap, though there are cheaper ones, and the adapters work at both 10 and 100 Mb rates. The hub does not handle both speeds, though, and it does not do full duplex. I don't think the adapters do full duplex either. I've been satisfied with this hardware, since it was cheap a couple of years ago when I got it (boards were under $40 and hub was $175. It's true, the hub is really small (abut 1/10 the size of my Thomas Conrad hub) but it does require externally transformed power. If you can justify it, a switching hub, capable of full duplex would perhaps be nicer, since you then don't have to string two hubs where one will do. It really does depend on the size of your LAN, though. A switching hub enables you to unify your setup onto a single logical segment so, unlike my setup, you only need one adapter in each box. I have two in the server, one for fast ethernet, and one for standard. When I started out, I had 15 stations, 1 Netware server, 3 boxes running Win/DOS, Win9x,NT, (interchangeably) and 11 running versions of *nix. I've eliminated all the *nix boxes and replaced them with a single one running NT or whatever is on the interchangeable drive. It's been 2-3 months since the last time I booted one of the *nix setups. With them out of the picture, the LAN is much more manageable. The only problem is finding a TCP/IP handler for DOS that isn't bigger than the NETWARE shell. If it's 500 bytes bigger, my essential DOS applications don't work for lack of low memory.

Semi-OT: Running CAT5 Cables

by edick＠idcomm.com

I'll reaffirm that! My 10BT LJ3 is attached to my NETWARE lan via coax and the rest of the LAN uses 100BTx or coax. The 10BT is provided by a HUB connected to the coax segment via one of those little AUI <=> coax adapters. These slightly larger than a small matchbox devices are often just lying on the ground or in a junk box at your local computer-junk-dealers' place It's often cheaper to offer $5 for a box of stuff containing one or more of these plus a bunch of stuff you probably won't need than to pick it out and offer to buy just the adapter.

Semi-OT: Running CAT5 Cables (Stupid Question)

by dylanb＠sympatico.ca

I have done substantial work with 10BaseT and running a network over "phone cable" is not a good idea. It is called "twisted pair" for a reason. We got some garbage uncertified network cables once that caused a whole bunch of problems. Flat phone wire cable is not the way to go [it might work for you]. john -----Original Message----- From: Zane H.

Structural Damage Question

A "live" load is one where the load is not constant or is moving. IE: people, wind, etc... A "dead" load is a load that is constant or does not move. IE: the structure itself. Although local building codes dictate what loads the building must support, they are usually pretty consistent. I did a search and found the following reference: According to the 1991 standard building code: Occupancy or Use Live Load (psf) ------------------------------------------------------------------- Libraries: Reading rooms 60 Stack rooms (books and shelving) 125 Corridors, above first floor 80 Residential: Multifamily houses; Private apartments 40 Public rooms 100 Corridors 80 Dwellings: Sleeping rooms 30 Attics with storage 30 Attics without storage 10 All other rooms 40 So, for a 20' X 20' room in your building the allowable load should be: 20 x 20 X 40(psf) = 16,000 lbs. If one of your neighbors has a large book collection, they may be putting a greater load on the building than you are... :-) Steve Robertson - <steverob(a)hotoffice.com>

Free Arcserve Parts (Was: Re: Semi-OT: Running CAT5 Cables)

by lance＠costanzo.net

This talk of 10b2 reminded me of something. I've got an arcserve hub, some cables (laying in my driveway), and about a 1/2 dozen arcserve cards in some old 5150's. I have absolutely no use or software for them. Free for the shipping (from California). Lance.

Semi-OT: Running CAT5 Cables

>Does anyone know of any sources of info on the net anywhere on running a >network between various rooms in a house? As an authoratitive reference on the subject, I *highly* recommend the Three Stooges' _A Plumbing We Will Go_. Shortly after moving to Canada I was very confused when my electric bill was called the "Hydro bill", but Larry, Moe, and Curly cleared this all up for me. Tim.
