Thanks for the confirmation.  From what I can see, all the cabling appears secure.  I'm not sure how to get at
the power supply, though.  Having removed the side and front covers, and all of the screws obviously securing the power supply, I still can't free it.

What about the small battery linked to the reset button?  If it's shot,
would that affect power-on?  Also, does the reset button have a role in
power-on? 

Obviously an IBM newbie,
