i always liked to tinker with almost everything. there was a time where some screw and parts could still be lying about after putting back together something. that something could have been anything. kinda of still worked like (as the intention was to make it) better than before. then the numbers of orphan parts and widow screws lying about had shrinked considerably - i mean - it still happens today, and i like it :) but software... that is whole new story. to be continued...
