First of all, it's good to see you around again Virgil,

What cable does one use if the 'net access is through the cable company instead of a DSL line?

After the modem you will use cat5, cat5e etc as with most newer networks. Before the modem, cable will use the RG6 and I'm not sure of DSL.

Older networks, base 10, would use coax cable. Most of the equipment is pretty obscure now and I don't think you can even get those NIC cards in anything newer than a ISA slot configuration. The newer technology has really made those older networks obsolete by todays standards.

And I think you did the right thing to replace it.
