I am sure I once saw a 5160 XT with a power output socket (4 pin) mounted
on a palte in place of that removeable blanking plate above the keyboard
connecotr. It looked like an official IBM product, not a homebrew. But it
wasn't my machine so I couldn't pull the cover to investigate.

I've seen PC/XT machines with a drive mounting screw going up from underneath
I doubt very much if you'd distort a Tandon TM100 drive chassis casting
with that screw. More likely it was a right pain to fit said screw....
