We have an old server with 7.3.4 that we keep around for testing. You are in a no win situation... you won't be able to connect to 7.3.x from 9.2.x client.

Here is an attempt using 9.2 client:
SQL*Plus: Release 9.2.0.5.0 - Production on Fri Apr 8 08:45:27 2005

Copyright (c) 1982, 2002, Oracle Corporation. All rights reserved.

SQL> connect system/oracle_at_L73
ERROR:
ORA-24439: Connections to Oracle7 server are no longer supported

SQL> exit

Here is an attempt using 8.1.x client:
SQL*Plus: Release 8.1.7.0.0 - Production on Fri Apr 8 08:45:37 2005

(c) Copyright 2000 Oracle Corporation. All rights reserved.

SQL> connect system/oracle_at_L73
Connected.
SQL> exit
Disconnected from Oracle7 Server Release 7.3.4.0.0 - Production With the distributed, replication and parallel query options PL/SQL Release 2.3.4.0.0 - Production
