No. I've tried a Sun monitor and a VGA monitor with an adapter, neither display anything. I saw on the list archives that the pinouts are different between Sun and IBM, so I'm assuming that nothing but an IBM monitor, or the right adapter, is going to work.

So I'll definitely be needing AIX install media, then? Or are there any floppy images or the like available online that can reset the console?

Yeah, the case is already off. So I guess I'll try to get some AIX media from eBay and try to bypass the lock. Thanks for your help.
