I'd dare say they are extinct. Of course one might actually find either used in the field, but it'll be a million-to-one find. Sort of like finding that Amiga still controlling the school's HVAC or whatever. Average time of a T connector on a 10BASE2 networking flaking out was measured in months, it would be miraculous if you found a complete network working. -- Doug McIntyre doug@themcintyres.us
