It was great -- we'd plug in the 10baseT xcvr and one by one all the port lights on the central Cabletron TPT-MIMs would go solid. Most of the time, though, I'm using very short lengths, 2 cubits max, with the main length from the wall to the CPU handled by a 3 meter xcvr cable between the CPU and the 10baseT xcvr. The more stupid lengths come into play mainly for serial connections, where I only have the flat gray to go between the wall and CPU, but surprisingly they have also been pretty much uneventful, even the longest ones (~10-12 cubits). >Radio Shack lists duplex splitters for $4.95, we get them >from our supplier for $1.80. This may help as your network grows. Radio Shack sells 8 conductor duplex splitters? Didn't know that -- I'll have to check them out. Who is the other supplier?
