So... basically this thing has been butchered to heck and back; in addition to all the jumpers there are almost certainly some additional trace/pin cuts that might be devilishly hard to spot; to reliably convert this thing back it'd be a huge help to have the instructions for the mod as originally applied, and even if you *do* manage to convert it back you're going to have to live with having some ugly soldered jumper wires bypassing the aforementioned trace cuts.
Personally, if what I wanted was a 128k I'd go to the mat demanding a complete refund of the item as being nothing like as described. I'm sure it's *possible* to get it running again but right now it's a worthless wreck missing most of the important parts to be a "genuine" 128k; in addition to the hacked mainboard and blown-up analog you've got the wrong ROMs and floppy drive. Was it the American seller who ripped out the memory upgrade or the Italian guy who flipped it on you? The latter is obviously a sleazy liar, I'm just wondering where the blame for the stupidity lies.
The tragic thing here is personally I think the machine as-modified would have been far more interesting to have.
