SQL Dev/Data Miner is compatible with 220.127.116.11 and up.
For DB Releases prior to that (10.X and 11.1), you can use the standalone Data Mining Client (aka Oracle Data Miner Classic).
It is not as versatile as Data Miner but it will allow you build, test and apply models.
You will also be able to generate pl/sql code.
Here is the link to get to that download page for the older client:
