There is possibly only a few mm between the pcb and upper case, so all the large connectors would need to be removed - as you say, I only need one power connector, but even the 4 pin floppy power connector is too deep for the SD cards to align in the slot correctly. The big 40 way IDE will definitely have to come off and go the other side.Dave wrote:You'd just need to remove the HD power connector, because it's duplicated in the floppy power connector.

Would you emulate the 8049 on a chip level, or try to implement it's QL specific communication interface?Pr0f wrote:My first sub project will be to replace the 8049 with a propeller chip and support logic, to provide QL keyboard, sound and PS/2 keyboard and mouse.
