. . . Good stuff Sellam. Some comments: I think you under emphasise the garbage system. I have a PDP8L that came Here in Australia we also have "Council Cleanups" where periodically the local municipal councils pick up assorted larger rubbish if it is left by the side of the road on a predetermined Monday a few times a year. The result is lots of pickings during the preceding weekend. Unfortunately one needs to cruise around all day as the good looking stuff goes very quickly. In some places there are also "tip shops" where authorised scroungers (often charities) sell goods collected from a garbage tip (or "dump" in American). Around here we have establishments with names like Junktastic Park and Reverse Garbage. Do we want to mention the term Dumpster Diving in a primer? Hans
