I've made a little board to fit an Indivison ECS into the Amiga 1000.
It rotates every pin 180 around so that the Indy itself is facing away from the power supply. It's a little snug against the daughterboard, but as you can see, it fits.
And here it is all booted up; R2 approves.
These are super easy boards to build; I've uploaded the gerbers to OSH Park for anyone to print if they like. Grab some headers, solder and done.
