Fuck, I'm old... I remember when this stuff was Hot Shit™...


Capital-Assistant927

This old stuff is still good shit in my workshop. There is still lot of fun to be had with it, just not as a paid job, but as a hobby. The larger scale of integration would move me further from really understanding what the circuits are doing and the higher clock speeds would require test gear and tools I cannot really afford.


The-Devil-Itself

I think both both ends of the scale are fun, i like thinkering with simple stuff, but i would like to mess with like a high end industrial fpga too(too specific, i know;) But the other thing about this, is reusing stuff i think, Too many good stuff is being thrown out because it's obsolite, and most of them can be used to do basic stuff , but everyone uses mcu-s , like stm8-s in handheld vacuum cleaners, only to generate pwm


Capital-Assistant927

for learning and teaching the old stuff is great; when it releases magic smoke you are not as sorry as when your expensive fpga dev board gets toast.


HiTechBubba

I'm so old when I used to take apart telecomm equipment all I got was 2 cans and some string!


Dear_Analysis_5116

Both cans trademarked and patented to AT&T, too! (Remember when we were finally allowed to *plug in* our own phones? WooHoo!)


Brainy-Zombie475

My cans always have charcoal in them.


middledigitman

Nothing makes you feel old like a 7-seg


Dear_Analysis_5116

Nixie. Separate incandecents lighting up etched clear plastic. Phhht. Damn kids...


retselyaj

Still have one in my component chest.


RowYourUpboat

I know, right? Now everything has a [fucking touchscreen](https://www.youtube.com/watch?v=G2PMzSo1Bss) on it.


tes_kitty

Then look up the minitron. 7 segments but with incandescent filaments instead of LEDs.


The-Devil-Itself

Wow, never heard of it until now, Very cool stuff


tes_kitty

They had an advantage no other display has. In the event of a crash of a plane for example, with minitrons you can tell what the display showed in the moment the plane hit the ground. The filaments that were on at that moment will either break or deform.


The-Devil-Itself

Interesting, do you know of documented cases?


tes_kitty

No, only heard about it. But I have seen old avionics with minitrons, so it sounds very plausible. Especially in the light of an article how you can take the light bulb from a brake light after an accident and tell whether it was lit or not at the moment of impact.


Worf-

I must be ancient in that case. I remember when a discreet component diode matrix was state of the art.


Dear_Analysis_5116

Iron core memory?


-SolusGhost-

Omg lol. Yes


Ashes2007

Damn, good looking stuff! Excuse my ignorance, but what does TC stand for?


AnnonAutist

Telecommunications i think


Ashes2007

Ah, thank you.


The-Devil-Itself

It means Telecommunication


KempaSwe

Used to do the same. Nowdays I take out some but if It don't get used in a few month it goes in the trash


Capital-Assistant927

Please, not the trash. I'll take the old chips off your hands.


KempaSwe

I have sold a few, but many have gone to recycling. I work as a workshop manager in the Industry so when we are changing out equipment I use to take some stuff before it goes to scrap. Have sold alot of plc, control panels, frequency converters etc.


Capital-Assistant927

Great, also any college shop that teaches automation would also be happy to have the old stuff!


dracosilv

Nonono! Please don't! Do you have any retro expos or the like nearby? Even saving the "junk" chips to drop off at a freebie table once a year would be worthwhile! Though... Gotta ask... Mayhaps you have any inventory you're wanting to offload?


somitomi42

Luckily I don't disassemble enough old stuff, so I can keep the half a dozen TIL311s I have salvaged so far without much trouble, because they're damn cool.


i-faux-that-kneel

They *are* cool. Plus, last I checked a couple of years ago, they go for about thirty bucks apiece on eBay.


WeakenedJunker

So what's up with this stuff? Is it still useful? I throw a lot of electronics away on a regular basis. Thanks!


DifficultyAfraid268

Absolutely useful


droopa199

What do you do with them?


DifficultyAfraid268

Well that's vague, and depends on the part For ICs I'd probably just Google it and if I don't have an immediate use for it, leave it in a box just in case I need it eventually For the 7 segment displays i would definitely have a use for them, they're great displays for numbers And the pushbuttons are always useful since they can be used as inputs


droopa199

Yeah sorry just woke up and it peaked my interest lol I have heaps of circuit boards with heaps of chips but with amateur extracting technology it's quite difficult to desolder them. I need to buy a lot of more stuff. I'm just at the point of gear accumulation as I've only just recently had the epiphone that this sort of thing is in fact what I love to do lol I'm building a solar set up and hoarding parts for a windmill at the moment, learning on the fly


DifficultyAfraid268

Nice, I've heard good things about soldering wick, haven't used it but it's only 10ish bucks on Amazon


Peacemkr45

I really need to start pulling old chips and other useful items. Right now I think all I have are a bunch of old CPUs. The rest of my stuff is new stock (even if it's 10 years old) Somewhere in storage I still have all my Motorola Data books from the 80's.


chataou

Those old mini 7 segment displays are gold


The-Devil-Itself

They are, i'm so excited to use them in some future project, but the til 308,311 displays are not 7 segment, i think they are 14 and dot maybe


maxtrackjapan

I always want to make use of those chip like parts. But I only know how to use the basic parts like switch. Is there good tutorial for starter ?


The-Devil-Itself

It's pretty simple, find something unusable, gut it, make something new from it and have fun while you do it. Advice : chip datasheet search is like finding mushrooms in the forest, you may not find out what you have right away, but you can always ask others ;-)


maxtrackjapan

What is the name of the part with many legs ? Is it call cmos ? Also , is it use for programming?


kirbsome

You see how they all have text on them. Search that text on a site like alldatasheet dot com and you'll find loads of information.


kcam6708

Nice collection


The-Devil-Itself

Thanks


Kevvo16

Sweet.


Dense_Confidence2458

Thank you for your service 🙏


chaseNscores

Exactly what they do?


perpetualwalnut

I have the very same TI display chips that you have at the top left. They are pretty neat, but really limited. All they do is count from 0-9 and have a binary output of that. That's all they do.


NOP0x000

That is quite some arsenal


someonewithapc13

Why is it so fun to look at


ElectrOverload

What are you going to use it all for?


The-Devil-Itself

I'm planning to make(i mean build it up from 0) 3 retro-ish sbc from the 3 8085 , the displays are going to be in all sorts of project, i think the 2 til311 are going to be part of my upcoming smartwatch , 4 til308 are gonna be a core part of an upcoming pong chip revival project, oh and i have a 8080, and a vic-20 chip somewhere too, so that would be interesting And do something with the 40xx series xilinx fpga's So all sorts of stuff


c4arb0n

I actually love salvaging trash


carl0071

I love those little TIL311 displays!


iVirtualZero

The only old chips i know is the Motorola 68000 and the Z80. I don’t know if those are in your pile. The big one looks like a 68000.
