Yes it is posible with coax cable BNC connectors and cards.
But why???
One switch cost about 30-40$

You will need to fit 2 network cards to one of the systems and a card in each of the other machines, connect together using cross over patch leads. Using TCP/IP give all the machines IP addresses within the range 192.168.1.x
subnet 255.255.255.0. To access the internet from all the pc's you will need windows 98SE or better and configure internet sharing.

If TCP/IP configuration suggested by glynn010257 won't work you should configure your PC's like this:
ComputerA with 2 network cards:
card1 - IP 192.168.0.1 - netmask 255.255.255.0
card2 - IP 192.168.1.1 - netmask 255.255.255.0

computer connected to ComputerA by card1
IP 192.168.0.2 - netmask 255.255.255.0 default gateway 192.168.0.1

computer connected to ComputerA by card2
IP IP 192.168.1.2 - netmask 255.255.255.0 default gateway 192.168.1.1

and now you can share internet connection from computerA to all other computers.

I'm not sure if those 2 other computers will see each other (they will se computerA), but Internet will be accessible from all of them.

Since "ComputerA" in the above answer is acting as a router then you will have to have the other two PCs on seperate logical networks.

The above answer should work just fine.

If your internet connection is dialup or USB connection, then yes - as described above. Else, no.
