I think the playstations aren't worth reselling. That NES top loader on the other hand ... I just need to find the extra pieces parts to test it out.
I was told the Mac Book should work, but I'd need a ps to test and think it is pretty old (as far as Mac Books go).
Growler testers are selling on eBay. It's a heavy S.O.B. but they are going for 30 to 40 bucks. The boards on the bottom of the third pic are telecom I believe.
I also need to look into the plasma centrifuge thingy. I think reselling anything worth more than 20 on eBay will help me recover my costs, then the computer scrap becomes all profit. I really need to set up a proper work bench space if I'm going to do this kind of thing.
