If you have no controllers, you have no way to talk to the drives. The only think you could do is pull the ADMs and put them in an XServe G4 and secure erase them, or, remove the actual drives from each ADM and use a USB to IDE adapter to connect them to a Mac or PC and secure erase them that way.

7 pass 1/0's is obsolete, one pass is sufficient per NIST SP 800-88. But using one of the supported ATA sanitize or secure erase commands is the preferred method of purging data from HDDs and SSDs, not overwriting. Unfortunately Apple doesn't support these commands, so purge method of sanitization isn't possible, only the clear method is. If you really need to "secure erase" drives at all, pull the drives and put them into something that can boot a Linux LiveCD, and use hdparm to initiate an appropriate drive firmare ATA based sanitize command.
