Welcome to Boardsort™ - Learn - Sell - Profit -

I searched everywhere to try to find these before I sent this. Any help would be greatly appreciated.

Someone is going out of their way to be different!
:)

1)I’m running a database scan on this but nothing yet. Gold cap ICs, and CMCs. My guess is memory. This doesn’t have any permanence in classing. I’ve had similar boards range from gold cap chip board (steel pins) to 486 class (heavy gold plated copper pins on gold sandwich board). Ultimately it depends on what it is. A search on my end could take up to 2 days if I have it recorded somewhere. If it’s just plain old memory you’re on the lower end, at gold cap chip board. If one of those IC gold caps, or the back, hide a controller it will be a 64-series Motorola/TI or a 40k series intel controller which makes all the difference in the ‘boards’ value.


2)need to email Chris for exact class on this. This design isn’t common.

3)with pins, amd aluminium top, no pins is pinless
4)with pins pentium/Mac ceramic, no pins is pinless
5)where’d you find that? With pins black fibre. No pins green/brown fibre no metal

6)DLP, can’t tell if ceramic or fibre

That first one; there’s really two options. You can ask Chris for a blanket value which generally sticks firm regardless of what I find out (Chris is boss), or wait a few days and I’ll do a full database search and see what it is for sure; if I can find it. Which I will post and could substantially raise, or lower, that value in boardsort’s eyes.

I second lost, where did any of those come from/out of?

#1 reminds me of some stuff I was paid to dissasemble a few years ago, several different items in that lot, some decade old graphing calculators and cnc routers/engravers

I never did get back here did I. That’s an ASCU.
Do keep in mind the classes have ALL changed since the time of posting

I am super fascinated by #2. I'd love to know what it came from, too. I think it triggered some deep-seated sense memory just looking at it. I want it! Then again, if I start collecting Xilinx stuff, my wife will probably kill me. But dang if FPGAs aren't attractive... if you're not quite right in the head and are into the vague and difficult to categorize.

Every time I look at #1 I get gold fever and have to stare at my 486 and 70s 80s gold chip collection.

I have zero idea what 1 is. Still have no idea. It’s an ASIC of some sort with nothing I can find a reference manual for.

Okay, did more than a bit of searching.

Here is something very similar to #1 mounted to a board.

I think it might be space-grade?

Also, does that img #2 Xilinx chip look familiar? It's got the same pin pattern, if not the same cap writing. Did it come from the same sort of board?

Well, my teething daughter kept me up most of the night, so I played around looking for #1. They're SRAM modules. Here's a datasheet for the two larger IDT 7M624S30s.

Knowing what it is doesn't really help, does it? Now I just want to know what this stuff came out of even more. Other very similar IDT SRAM modules are used in lots of aerospace and military applications... I've got a mental image of somebody bringing a disassembled Tomahawk to Discovery's scrap yard.

Ah, progress!
Xilinx Was founded in the early 80s. They are principally a custom design company making flexible redesign components to order.

So I’m ow digging. Looks like those ram modules are bus locked. Meaning direct link. Combined with minimal fault tolerance:
Looks like a fail-safe system vs a fail-quick.
If correct we’re out of aerospace and into defence, and energy.
The posted board is an I/O controller module.

Most aeronautics equipment is fail-fast or fail-quick. Trigger a fault, deploy counter, and shut down. Be it dropping o2 masks and starting internal pumps. Or auto trigger ejection. In drone such systems are used to do a data dump of video/photos. Fail-quick allows override. Fail-fast eliminates human error.
Fail-safe systems do a number of protection tasks and wait for input.
Dump coolant into a tank, turn on emergency pumps, switch to backups. Ups: close programs and shut down.
Disarm. ;)

I’m laughing at the previous post. The mental image.
One of my yards buys almost everything. Thinking of a flatbed with a fully dissected tomahawk.... CSL.

Uh, it fell out of the sky? Lmao.
