content: That "telecomms" board is actually a set of test/serdes characterization and development boards for the recently-defunct Tabula corp which aimed to bring out new FPGAs. Basically, by using time division multiplexing on the LUTs with a faster clock you could increase the capacity by an order of magnitude.

I am totally OK with the price for them as collectors' items, but for gold recovery, there's no way that is worthwhile, right??(For context, right now, gold is about US$50/gram. Given how thin the gold platings are, I doubt there's 11g of gold in those 22 CPUs. And that's if somehow the gold recovery process were free, which it's not.)

content: The part number (21-01170-01) is from Digital Equipment Corporation (DEC), which had factories near to the item's location, in Maynard and Marlborough, Mass. I have not seen that part before, and it doesn't appear to be indexed by G**gle anywhere.My wild-ass-guess would be that it has something to do with the VAX 9000 (Aquarius), which was a VAX supercomputer with vector extensions. The mezzanine connector looks like a FCI Meg-Array 10022671. These chips are probably not usable by breaking bond wires due to rough handling.Incidentally, your "divide by cucumber error" sig is relevant to DEC microcircuits. The engineers there published a joke paper about "organic light emitting materials" in which they stuck electrodes into a pickle. That inside joke became the code number for Alpha CPUs, which were numbered EVxx for "Electro Vlasic" (Vlasic is a brand of pickle). EV also could stand for "Extended VAX", but the joke explanation for the name was preferred.

content: Quote from: daqq on October 19, 2021, 05:32:01 amOf course. Recycling in general and recovery of precious metals is good. I should have been more specific.What bugs me about the ebay 'scrap recovery' area is the very high degree of irrational expectations. What's needed is a way for people with old junk to easily pass it to expert industrail scale recovery operations. Entities with sensible, non-poluting, economically viable production line processes. Where the price offered for items to be scrapped, would be an actual sane estimate of the value of recovered gold etc, minus processing costs, plus a profit margin.Instead, in that ebay category it's the norm to see stuff listed for what must be multiples of the actual recoverable gold cost, because the sellers are idiots and have an audience of idiots, all with 'gold fever' - it's shiny, must be worth heaps! Thus often pricing it out of the range of historical collectors.Gyro's posted two fine examples of completely irrational pricing.OK, it's a free market, but a very irrational one, because 'gold recovery' is such a cult of amateurs who have little idea what they are doing. Of course there are some who DO know what they are doing - some interesting youtube channels about gold recovery. Though I never saw one that added up their costs of chemicals, time, etc and worked out an actual operating margin.In general irrational pricing in a market is no big deal - just a bunch of extortionists and suckers interacting. Except that in this case quite often there are real historical treasures being destroyed. With the sellers having no clue or care. Antistatic handling? What's that?But hey, it's the same with everything isn't it? Ignorant bozos getting their hands on treasures they don't understand, and destroying them carelessly.Also... every time I look in that area of ebay, I end up blowing cash. This time... 304188959597 Gold Plated Can and Transistor Legs Scrap Electronics 7.2 Oz Price US$50!For some metal can ICs with gold plated legs. Appear to be socket pulls. But I notice they are Burr Brown, and at least some of them seem to be INA-1xx series. Looking them up, seem interesting.I got them for $42, which is still way too much for a collection whim.Anyone care to make an estimate on how much (little) actual gold is there? Not that I really care.

The casing also seems to be gilded, could have a more area than pins together on the inside, not sure of construction. Wide bonding was done in gold as well, would assume that to be the case here. Assuming a 100% efficient process and not accounting for time and materials, then you are well in the plus.

So how is this even worthwhile to ship somewhere by post. Someone is asking 20 USD for a kg of PCB, that has to be a scam, or bad valuation, right?

For the new stuff the yield is very small IIRC though.

content: Non-working GPUs, sell on ebay, for just about the price of the working unit. And currently, the average GPU sells for around maybe +2x it's paper value.Broken GPU's are basically not worth fixing at this point, why bother to save 100$, for something thats probably already 2-3 yrs old

content: Quote from: free_electron on March 02, 2022, 03:25:03 amIdiots who watched gold recovery videos on YouTube too much. Even if they can recover that gold to cover the cost of the scrap, chemicals which are requires will eat up any possible profit and lot of time is needed to be spent.

content: Broken GPU's sell for about 80-90% of the price of working GPU's. There must be next to no profit these days, in trying to buy broken GPU's, and fix them and sell them. The market is that screwed up. Between scalpers, miners, the supply chain shutdowns, the duopoly of Nvidia and AMD, and some big retailers, they have made GPU's largely unavailable, and unaffordable, to the average poor working person, let alone kids/teens that might want to save up for a GPU.Wow I thought about this yesterday ?

content: Quote from: Ranayna on October 14, 2022, 10:14:27 pmIf I had zero morals: make some "antique" looking PCB layouts, and just dropship to buyers.Now you make me think though, how much gold is would be on a 100% plated JLC board:QuoteSo 100x100mm x 2 of 0.05um thickness is what 0.000000001m2? 0.5mm3That should be 10mg of gold if true (50c worth), more than I was expecting. JLC charges ~60-80c per board.
