Welcome to Boardsort™ - Learn - Sell - Profit -

I have 29 of reader type #1, and 7 of type 2. #2 has a small IBM flip chip in an hour typical aluminum can. Realize this isn't the normal stuff that you guys Harley deal with oh, but then again maybe you do. Any insight would be most welcome thank you.

Still trying to figure out your system with the pictures.

While they’re dirty aluminium. You can pop the chips for IC rate on them.

crappy pics. Appears to have gold wire in the mylar, and possibly a silver/ or pd wire soldered to the tip.

Here is some scale.

It does. And rhodium. Etc etc. The weight ratios don’t add up. As is it’s dirty aluminium. You can pop the ICs and it’s still dirty aluminium. I also cut the rhodium beads because I have a buyer, it’s worth many levels above gold, and the do slowly add up. Plus my buyer will buy it above 4 grains. So it doesn’t take long to be able to sell it for me.

The gold just isn’t expensive enough for me to deal with it. If there’s a bad arm break in a drive, the work already being done for me then, I’ll pull the gold wires and toss them with my pins.

Keeping in mind that gold is in the $1450-$1700 range depending on location: and rhodium is over $8000 per tyoz

Can you post a pic of the rhodium beads plz.

The rhodium is part of the read head. The actual tiny head. And it’s just one fraction of the weight of the whole head. But as I said looking up a rhodium buyer online...
Rhodium is the most expensive non-radioactive metal and has been for a long time.
It’s why some companies still try to recover and recycle LCD screens. Though that market has just about given up as a buyer vs paying for recycling.
You find it in a slightly larger quantity in laser guided read heads, eg magnetio-optical like floptical drives. It’s also the reason that hard drive cassette readers (the fridge sized machine with the read heads that takes magnetic platter cartridge) currently sell for many many many thousands. Over all they’re not much different from a modern hard drive. Along with apx an ounce of gold from the head wires and many pounds of silver, there’s nearly a quarter ounce (four head) to half an ounce (8 head) of rhodium.
It’s a rare example of spending 50K on a collectible may still pay more in scrap.
...Then again there’s many pounds of gold leg components that would range from a few dollars all the way up to 8086 class ICs on today’s list in an 1131.
And a crap load of copper, steel, nickel, aluminium... —>
The last time I saw an 1131 sell it went for $75000 before commissions back in 2018.
