Hi folks. I thought i'd have a go at making a device that allows the connection of a 3.5" dive to a cpc 464 without modifying either the drive or the ddi-1 board.
A simple plug and play if you will.
However I'm not very clued up in electronics and possibly (definitely) should have asked someone who was if my circuit was correct before plugging everything in.
Long story short, I've accidentally plugged my ddi-1 ribbon in the wrong way round, got some magic smoke at the power connector to my board.
After plugging it in the correct way, i'm getting voltage drop across the +5v pins on the DDI-1 board where the ribbon comes in. This is making me think i've somehow made the circuit series rather than parallel or i've destroyed something.
The more i look at the diagram i drew, the more i confuse myself.
