Here as promised are the photos from my efforts to expand my QL to 640KB and also fit the new power board to replace the 7805 regulator. You can see the original board and then the "slimline" version I had to produce on the fly after it became clear the original sat way too high to fit inside the case. This probably explains why people bought the expansions that fitted the Eurocard connector. You can also see the replacement Microdrive ribbon cables, these are parts from Farnell and work a lot better than the originals as they have proper metal ends to fit into the sockets rather than the tinned wire ends of the original cables that had no strength to them to push into the sockets. The final couple of photos show the QL after all the upgrades fitted and the Minerva boot screen showing available RAM.
