I personally haven't done any with that lid type but there's the money boards. 8)

Where do you guys find junkyards that will let you in the back. :evil:

Clearly, those chips have a cap soldered or glued in place atop a gold rectangle. Who here knows the composition of those caps?

Steel, it is best to run them seperatly from any thing else you run.

Thanks, Barren, I fantasized they might be Pd-plated or something similar, but I have seen enough of those with corrosion to reject that possibility.

Couple of today's finds.

1. Heavy duty GOLD Harness and Coupler .. took 10 minutes to wrestle that out of the mangled connector. Application ???

2. Zilog 1979 Ceramics in background

3. I think I dug up some ancient magnetic core memory boards ( know nothing about them ) DIGITAL CORP ? i'll clean those up and post for review if anybody wishes

With regards to Junkyard access and these finds, it was basically luck.. I work multiple accounts and these pieces were someones trash 20 years ago thrown in a scrap metal yard. I know I should be working my other accounts, but I'm addicted to digging this stuff up

NEC's version of the 4116 16K Dynamic Ram chip. I knew them well! When I think of all the bad chips and boards I threw out back in the 80's before I got interested in gold...

is this the FANUC version of the NEC 950 .. ?? .. am finding next to the NEC 950 / 951, so I'm wondering if they serve the same function .. i just love the color of the ceramic .. very unique .. not to mention the insides .. good evening for now

Actually the NEC part number is the UPD416D portion. The first character is actually a Mu symbol not a letter U, but I don't have an easy way to type one. The D at the end indicates the access speed in nanoseconds which if (my) memory serves is 300ns. The other number 950, 951, etc, is the date code.

I always thought the purple ceramic looked classy too. As for your purple and black chips those are I believe most likely made by Fairchild or maybe Fujitsu, but their logos have changed over the years and I'm no longer certain which it is. They're definitely not made by Fanuc though. In either case yes they are another version of the once popular 4116 ram chip.

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.

I think I have those same exact boards...haha. I will check.

Couple of New Ones to Me .. Western Electric ??

 

[oldgoldman]

Weitek 3170 .. also new to me ..

 

[glorycloud]

I have always thought the Weitek chips were pretty chips.

Seems like I have sold a few that I have desoldered to collectors
to save them from a crushing blow from Mr. Hammer and the ensuing
acid bath. 8)

Yes Western Electric brand, apparently some sort of multichip modules. They quite likely contain gold interconnecting traces too. I've been really impressed with the recent finds on display here. Wish I was so lucky.

Thank you for the compliment. My intent with this lingering thread is not to brag or show off, but to share, preserve and enjoy these rare pieces with all on the forum. I'm not a refiner like all of you. I'm an entrepreneur who enjoys the hunt. I will need your individual help in the near future to convert some of these babies to $$s. ( Pins, Chips, etc )

Now .. back to business .. anybody ever dealt with these Dynatech Racks .. they are very time consuming to take apart, but gold looks painted on and they have some thick 1/2" long pins in the middle when you filet open the individual modules.

Happy, Healthy safe weekend to all.

Additional components for your review from the same module that yielded the above WE Gold Leg chips .. Hope these have good yields. I'm worried about butchering the braze on the tophat .. 3 simple through hole leads on the back ..

Just heat the solder up a little bit till the part dislodges from the board and you will be ok. No damage to the part.
