Have spent the last few days wiring up extra connectors to get Minimig running on the DLB.
First up was the SD card connector. After miscalculating the physical constraints and putting together a makeshift "board on a string" I was utterly amazed to see the Amiga Kickstart screen - especially considering I still can't successfully build the native DE2 project from Tobias!
No PS/2 input - which turned out to be the extra 'key' inputs hard-wired to all active, so I couldn't bring up the on-screen-display. Discovered this after <CTRL><LALT><RALT> actually rebooted the Amiga...
After fixing that I could insert a floppy disk image - but the Amiga refuses to recognise a disk in the drive... a problem I am yet to solve.
I re-did the Minimig add-on board - this time it interfaces via an empty 42-pin IC socket which gives me more options and physically more room on the board.
Next attachment is the 2nd PS/2 connector for the mouse. It's working in Space Invaders but am yet to see it in Minimig...
Finally I added a (redundant as I soon realised) gamecube connector to act as the joystick input. It's redundant because I can still use the other header! Doh! However the up-side is that by re-soldering 1 wire I now have a 2nd gamecube controller input! I'm waiting for another build to complete (~40mins) so I can press the joystick 'fire' button during booting to bring up the Kickstart config screen which should also let me test the mouse input...
UPDATE: the mouse works!
