Welcome to Boardsort™ - Learn - Sell - Profit -

I recently bought some circuit boards in an auction. I was wondering how these would be classified, or even if there was any collectable value.

Also I have some regular small ICs that have gold legs how are they classified?

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.

0003 is binary register 00000011
Alt b on Dec trainers

My typical test cycle on 4004 and 4040 CPUs is a 100 word entry per register, twice. Any register that faults over 49% should be considered a bad chip.
If you include the printout with the CPU you boost the value a bit.

Thank you for your help, unfortunately I dont have any way to test them. I guess I will see if I can find anyone who is interested in the chips as untested. Otherwise they will be scrapped.

Also how are regular 16 leg socketed ICs with gold legs classified?

Depends on the IC but the ceramic ones usually will be pentium if there's no gold cap.
Plastic with gold legs I put on green fibre.

You can email me. I'd make an offer but I should be your last resort since I'm not going to be much higher than boardsort is. Probably around $30-50 depending on what they look like out of the sockets.

Thank you I will keep that in in mind.

And Offering only because any that don't work would end up at boardsort.
In case anyone wants to call me on circumvention.
