While I agree that upgrading the machines should be seriously considered, Linux might not be a possible solution. LINUX assumes at least a 32bit processor and that might not be available on machines that are not even running MS Windows.

But he might be able to use the machines as terminals, using telnet. Then sqlplus would be running on the server.

Advantages
Keep old hardware OS at departments.
run latest OS and Oracle on the server.

Disadvantages
local functionality is missing, like printing. (e.g., the SPOOL command would save files on the server which would have to be moved to the client machine for storing/editting/printing)

About even
communication issues would seem to be similar whether running thin clients (telnet to server running Oracle) or fat clients (sqlplus on the department machine)
