Let's appreciate the fact that the DIP package still exists as of today.

Those came out of ITT Defence, collaboration with General Electric, for a airframe module for switching redundancy while also isolating a bad group from the remaining good group, these were in banks, stacked to the gills on top of each other.. lever lock bulkhead pinblocks.. would also allow for a series if token ring endlessly, while knowing how to automatically isolate one group if diagnostic discovered one bad, it would know each cycle to not include the bad one on the route check.. they worked well, but other means were formulated that were faster diagnostics, easier to build, smaller system, higher voltage ranges on the newer units as well . Obsolete.. you can find these frame control modules decouplers/decoupler units on F-4 Phantoms, 1&2's, and one of the generations for the U-1's... Short lived though on the heli's...they were just too big and clunky.. but, who cares that a billion plus dollars was spent on that campaign to design them, I'm sure, the tax payers didnt care... Lol

It's really interesting to see transistors that you can almost see with the naked eye and make out the parts. To think that this would shrink to be less than 1um big

1969, at that time, still lots of valves and germanium transistors dominated the consumer electronics, and then you see this hybrid IC and it blows your mind such a thing was being made back then.

I could see this being enlarged and used in a Star Wars type setting- the various shapes, and the colors of the ceramic and gold circuitry look like something off of a Y-Wing, controls or ship greebles or something! This one is really fun to look at.

Amazing!! 1969!!

You might consider looking into focus stacking software mate, with that narrow depth of field it could help get some crispy images

A possibility: Textron Inc.

In my opinion the chips were made by Fairchild Semiconductor. Fairchild Semiconductor was one of the best electronics manufacturers in the world and pioneers. Gordon Moore the founder of Intel worked there.

Hmmm, I had a relative in NY State who made chips back then for the military. Wonder if it's one of theirs?

DTL logic, I once came across some surplus PCBs in the early 80s with double size plastic DIPs. 16 pin .2 pitch legs.

Awesome

I worked with the I-Hawk missile system for the US Army and it's computer was a refridgerator sized cabinet with multiple pull-out vertically mounted slider drawers. Inside were 100s of 5" x 4" cards stuck into slots that had 2" gold finger protrusions on the back allowing wire-wrap inter-connection, insane to trouble shoot. Anyway, these chips (like your special hybrid) were the make up of these very basic elemental logic boards, all constructed via wire-wrap to assemble a single 18 bit micro computer. Probably a military governmental chip, many are obsolete the day they field.

I still have some old data books and might go and check this. This is likely some very special purpose circuit.

It's also possible the trimming was done with sand-blasting.

These videos are awesome! Thanks! Would you able to do a series on evwry component in the Iphone 4?

Wow, that was pretty sophisticated for its time. Seems like military application, but the construction of the package seems less robust than i would expect for a military application. Hmmm.

Ahh, 1969. I was made that year as well

What do you want to bet - its an HP creation, for their test equipment line ... they could afford this sort of tech for leading edge performance and repeatability.

There's some solid gold.

Well made

Texas instruments is my guess.

Nice

It's made from Pure gold

History in the making 👍

I've seen those types, even today

You should trace the chip out and post the schematic online...

i can not Imagine they used laser trimming in 69

Sorry, I don't have access to this information any longer or I'd look it up for you.

1969. 😎

Honeywell

That is pretty interesting

Cool chip

IBM

I am stunned , 69 , i was one year old

Лакомый кусочек для афинажников.

Oh yeah,that was me…I forgot to write it on there…

А на них можна дивитися?

lots of gold

Aliens?

Its from Heathkit.

idfk wat ur talking bout!

Nice
