OT. Networking problem

[Mick Howe]

I have a client with a 6 station ethernet coax network made up of Pentiums.

Last thursday in the extreme heat one of their boxen collapsed and I have 
replaced it with a duron 1100mhz that doesn't have any ISA slots.

I am unable to find a PCI NIC with bnc connector and the client is reluctant 
to change over to RJ45 wiring. (5 x 25 metre runs plus a hub)

Can anyone offer me a simple solution as I have struck a mental block on this.
