Junkyard Find

[oldgoldman]

Apologize if this board has been posted before. I'd call it a survivor board .. obviously not functional, nevertheless beautiful in it's own way with 23 motorola ceramics on it.

Enjoy

Nice find! :lol:

 

[escrap]

And in a Junkyard. I wish I could get every single board that heads to the scrap heap.

What a find! I was just curious, because I've never been to a scrap yard. How does it generally work? Do you just walk in and pay for what you find? Do you pay by the pound? How would someone working at the yard even know what it is you just found? That's a gem! What did they say when you walked up with that? Thanks in advance for any feedback! I'm a student, and I try to keep my overall costs as low as possible: thrift shops, dumpster diving, and things like that. This sounds like another lucrative source of material!

Sorry for the late response. Welcome to a new and exciting hobby / business. I always pay by the pound and have my company checkbook with me at all times .. as you never know what you'll see. For me personally, the thrill of finding a new under-developed source of material gets me out of bed in the morning. Calculated speculation on materials through years of experience gives me the adrenaline rush I need. With regard to this specific board, it weighs 4 lbs .. with tons of ceramics as you see. If we conservatively say it is in the $75 / lb range, then you just got $300 for the price of a value meal. These are the exceptions, but through my normal course of business, I peel off the special items like this both for their cash value, and as an archive. Good Luck .. PM me if you need any advice.

Not even close.
It would be stretching it, to say it is worth half of that.If you desoldered the ceramic processors,you would have about 8.5 ounces of ceramic worth around $100/lb.($53).
Still a great find though.

okay 10 value meals for the price of 1 ..

Heck the way everything is going,I'd be happy to get 1 value meal for free.......so you made out like a bandit. :mrgreen:
Keep an eye on this thread,Im going to post some pics of my load today.....you guys will get a kick out of this.

 

[oldgoldman]

Mic .. looking forward to your pictures. I was at a new scrap joint today and asked if they had any old computer stuff they wanted to get rid of. He said follow the main road around, when you get to the broken down mail delivery truck take a right and about 4 vans down the row there is some old junk. Sure enough some ancient NCR boxes, ancient IBM stuff etc. Okay, so I had 20 minutes, so I started rifling through it and got these 2 boards among others. Then when I was leaving he said, " Maybe you should call Mr G. .. he has 30 years worth of ancient computer stuff .. He comes over here and stuffs our vans full .. but you have to catch him on his off day .. when he's not drinking " Well then .. I got Mr G's number. I'll keep you posted.

Grab all the vintage IBM stuff you can.Do you know what a TCM is?If not,send me a PM and I will educate you.But you need to keep an eye out for any of them.
Im setting everything up to take the pics now,so give me a little while.

You are tooooo funny. :mrgreen:
(Thermal Conduction Module) An IBM circuit packaging technique that seals chips, boards and components into a module that serves as a heat sink. TCMs are mostly water cooled, although some are air cooled.
Also known as an MCM ( Multi-chip Module),there is no way humanly possible you won't forget one if you ever see one.
They come in different packages,but the physical size is the same.
BTW,Im gonna start a new thread,showing the pics from todays load.I should have it up in a few minutes.

I have seen those posted here before. They are really quite something. My mind reels at the technology and man hours it must have taken to design and manufacture those. They must have cost a fortune when new. Now they are obsolete relics of a bygone era. They must have been the benchmark of computing power in their time. I imagine some machines somewhere are still running with those today. What were they used for?

 

[Anonymous]

What were they used for?

They are cpu's,that were used in massive servers and mainframes(at first),then they started using them on some smaller models.They weren' t around very long,which is another reason they are so darn hard to find.

 

[qst42know]

I would guess they are more valuable whole?

From this description what do you suppose 400 m of wiring stands for meters? Would those be fine gold wires?

Good Evening .. Based on earlier e-Bay recommendations ( thx ) .. I thought maybe this piece would be a good candidate for a pilot run ?1? ..

i believe it was element 47 .. have a look at this. 3.2 lb backplane remnant .. heavy duty .. Au content unknown .. estimated age 20+ years .. i hope the picture is good enough for the time being ..

thx

 

[qst42know]

I'd like to see a photo of the boards in the back.

A close photo of the chips.
