Hi Carl,
tftpdnld is not supported on 3660. The issue is that your IOS is corrupted. Please download your iOS again from the Cisco website, verify the MD5 checksum before uploading to the router.

also where should i download from cisco the IOS for this old router?
i just found this router at my company stock room... i know its working its just that i was put aside for awhile
