I have setup up personal oracle 7.3.4 on a win98 machine. Started the listener and connected from another machine. You should probably have a network card in the machine, if not you might be able to use dial-up networking. You need the tcp/ip protocol setup. You can use the loopback address 127.0.0.1. You can also just use bequeath. Maybe if you publish your listener.ora, tnsnames.ora and sqlnet.ora someone will help you to set them up. There are alot of variables when setting this up. You can also use odbc. that might be easier.

Good Luck,

Brian.
