If you know how to test it 1) The teletype CPU if it works should be in the $30-$50 range. They're not all that useful but the historical factor keeps working chips high. It's actually a 4040c06, a cut down 4040 with half length bus (2-bit x2) and a cycle controller built in for timing. A convoluted processor that was the computer equivalent of two cans and a string. Despite the missing gold cap it can still go in 8086. I've sent these before. You'll need a trainer to test it and make sure you torture test 0003. Known to be a bad register in otherwise good CPUs and if it's faulty lowers collectors value by about half.
2) see 3 3) looks soldered; gold cap chip board. The ones with gold pins; yes you could use a heat gun to remove them, keeping pins whole, for 8086 rate. However they (the little ones) weigh nothing. My suggestion is pull ONE and weigh it then do the weight math to see if it's worth your time. I'm not sure it would be. The white one in 2 is 486 class. Not worth pulling as the board is scrapped higher as gold cap board.
4) those NEC CPUs are 486 class. The cap is silver nickel, with heavy gold bond under, working worth $5 or so. There's a lot of them out there so the price stays low
5) 8086 class, not really collectible Unless it's working, then your in the $5-10 range.
