Now I just need to fix the PCB on the 231 (some idiot has gone and ripped a few tracks and pads off the board) and steal some parts (a PCB mounting screw!) from the 156... Given its wiring, I suspect SW1 is the drive select switch (it isn't fitted on either of my drives). What I don't get is why it's got three pins plus common. Common goes to the "SELECT" input on the controller chip, 1 goes to /SEL1 (pin 4), 2 apparently goes to /SEL0, and 3 carries the READY signal from the drive (?!). JP1 allows SEL0 and SELECT to be bridged without the switch present. The only way this would make sense is if switch pin 3 was open-circuit... -- Phil. classiccmp at philpem.me.uk http://www.philpem.me.uk/
