First off, the LANCity is a dark gray colour, metallic and looks like a slightly rounded rectangle with ten little fins on top. The TeraPro comes in two versions: one that is jet black and rectangular, and another version that is dark blue, which some subscribers liken to a shark fin. Both mainly consist of a plastic construction. The LANCity was one of the first kinds of cable modems that ever appeared on the market, way back in 1995. Developed by Massachusetts based LANCity Corporation, the company was soon bought out by Bay Networks. In turn, Bay Networks was acquired by Nortel Networks in 1998. Sadly, Nortel chose to discontinue the production of these impressive pieces of hardware after it consolidated Bay’s operations with its own.
