I have opened my 512K to reinsert the floppy drive and discovered a cable wrapped in sellotape to be in the air.Is it normal or not? I’ve post some images from the cable.
Not normal .. first guess is there used to be an accelerator in there, or maybe a hard drive, and that cable powered it. Someone removed the accelerator and taped up the end of the cable?
There is more going on here than those extra wires, what is the vertical mounted black box opposite of the analog board? Seems like a lot of hacks are in this system..
OK, my guess is that is a US spec ( ~120V ) system that was used in another country with different power ( ~220V ?? ). The wires went to/from this added internal power converter.
