radio security code unknown

Hello,
I have a '94 prizm that I just bought that has the radio security activated--but I don't have the code. I need to disconnect the battery but am afraid that the radio will not work afterwards. Does anyone know how to fix the radio after I disconnect the battery or have any suggestions? I really need to get this done but don't want to buy another radio.

I took care of the problem--the search function is a beautiful thing!

how do i get the security code for a delco model number
