Also the unsocketed chip looks to have been rather untidily soldered in position. Out of interest what did the machine quote as the available RAM when it was working, albeit briefly? As Sothie says the 416C and 4116 are pin compatible.
By the way my favourite contender for the intermittent power supply fault is the pin 4 connector in JP8.

Hi Alan. I've attached a couple of pictures of the front/back. It's a 2001 series, and the label at the back notes it as a 2001-16N BS. So it could be, as you suggested, upgraded. It was very brief (and just the once!) when the Commodore screen was displayed, and as far as I remember it was around 32k (minus some bytes). It does look a bit of a mess around the RAM area; it does seem that they were having a few problems!
Tim.
