I'm not pointing fingers, Gorgonops, but cut ribbon cables like this said that its a stolen Apple from somewhere. It is quite sad to see this.
And $75 for a Apple II(anything) with cut cables, to me takes off 90% of the price. I usually tell them of about the cut cables and then about the cost of "fixing the problem" and then haunt him until closing hours and see if he would let it go at 90% off! Machines like this usually wont sell unless somebody is desperate to replace an Apple for one reason or another, and usually at a haggled price.
For that reason, I separated the all 3.5 with the ejection button as for Apple IIs and 3.5 with a button for Macs in my mind. Its a limiting mindset I know, but it kept me out of trouble.
BTW - back in the day, Dr. Levinson figured out how replace a burnt out PROM with a 2704 or 2708 EPROM. He had to divide the data bus of the eprom into 2- 4 bit buses and set them in what I called a Spider adapter of wires into each of the PROM socket and then pull the addresses from one of the socket. It actually worked! He figured this out from a Chinese Clone Disk Drive card having an EPROM and not PROMs. But then after he got a hold of a several dozens of blank PROMs and figured out how to program them and lets say "He was happy as a pig in shit!"

You might be right on the Unidisk. To me they all looked the same and seen a few of them smoke when plugged into the wrong machine. It can be fixed if the PROMs survived - its usually a couple of 74XXX chips and solder a wire to replace a burnt out trace. I've done those for Dr. Levinson back in the 1990s.
