like I said in the other thread, it's worh it's weight in scrap value, until you find someone who wants to pay more for it.
same goes for personal value, only an individual can assign that for themselves... for example a voodoo 2 is worth more to me than a voodoo 5 because of the nostalgia attached to it because I used to own one back in the day.
unless it's something that is commonly needed for repairs of old equipment or has a definitive market like amigas or 3Dfx cards for example you can't just assign a value and be done with it.
also not to sound condescending, but you shouldn't expect other people to do the research for your own eventual monetary benefit, that's not how forums work, if it's a technical topic that everyone is interested in people enjoy spending time to solve issues to help others... but helping others make money off of old hardware is not the goal imho.
