I have a very old 24" iMac (model A1225, early 2008) that I want to hook up to my old iMac (27", late 2012) as a dual (not a mirror) monitor. What connector/adapter/cable do I need in order to do this? Please make your answer VERY elementary, and thanks!
iMac 27", macOS 10.14
No sorry, the Early 2008 iMac is to old and does not meet the requirements for Target Display Mode.

Sure, tlslex, I'll give it a try. Hold it...breaking news.., I was thinking of TDM, but, Target Display Mode is only officially on imacs from 2009 and later, but was dropped about 2014. So, your iMac from 2012 qualifies, but your 2008 iMac does not. You could try ScreenRecycler.......

Is there a way to do it using an external adaptor?
The 2012 iMac has 2 Thunderbolt ports and a Mini DisplayPort output with support for DVI, VGA and dual-link DVI. The 2008 iMac says it has a "mini-DVI that says it supports external display is dual display and mirroring modes. VGA output supported by optional Apple DVI-to-VGA adapter (sold separately)"
Can it be used for screen sharing, 'den.thed'?
Any advice on HOW to do that, if it's possible?
Perhaps with ScreenRecycler or another VNC, but they are slow and clumsy.
No it will not work. The iMac's are all-in-one computers, not computer displays.
