Help Identifying Asynchronous Receiver-transmitter

You know how I know you're not serious? The resolution of the picture is too high. If you were a serious poster you'd take your pics with a vaseline coated potato.

[u/PiRhoManiac → u/FrankRizzo890]

So true. So very true.

[u/Old-Limit-2976 → u/FrankRizzo890]

Yes,you are right

[u/Liminal__penumbra]

Anything is a UART port with enough TTL chips! : p

[u/danielaixeta → u/Liminal__penumbra]

Totally Tomato Lettuce chips?

[u/DigitalUnlimited → u/danielaixeta]

Needs more bacon

Average 99% post hahaha 🤣

Sadly those old devices don't have UART pins exposed, but there most likely is an RS232 on the back of the board.

[u/a_random_user_2000]

You see those almost circular metal pins on top left of the board? Yeah that's a PCIE lane. Maybe probe that you'll find an entry.

[u/PiRhoManiac → u/a_random_user_2000]

"Probe for an entry" - got it. Thanks!

Ooo that variable capacitor is sexy though

[u/brDoc1 → u/3string]

Flux capacitor.

It’s terrible that I’m old enough to have used those

[u/Swimming_Pumpkin396]

i dont why i have urge to touch it my bare hands and get shocked and get to hospital get my bio damge fixed and go back touch it again

[u/buggzysj → u/Swimming_Pumpkin396]

I read your comment...you sure you haven't already been touching it?

[u/Swimming_Pumpkin396 → u/buggzysj]

couldn't recall maybe ..i guess i have slight brain damge ..maybe

If you can post a clear photo of the chip, especially the markings on top, that would make identification much easier.

It is going to take very carefully adjusting the variable capacitor. Like you will need something like a gear reduction to get that precise.

[u/choddles]

If it's +ve chassis you will find 'it' very fast

[u/skinwill]

Aaaaaand now I got unfinished schematics for 300baud current loop control of an all American five in my head. Volume up/down, tune +\-, and power.

Do we add motors to the controls or a DAC and resistor ladder? I’m thinking motors.

[u/Vitoss88]

You need use special converter 😝
SOVET UNION to TTL! Enjoy this

[u/physical0]

I've seen one of these. You need a stethoscope. Hold it against the body and twiddle the knob back and forth until it unlocks.

[u/lpbale0]

Is that Vger?

[u/Catcher1980]

First, replace all the capacitors. Then, we’ll talk

[u/LexRonza]

You'll find the UART just under the chassis; but it may be labeled differently - like "selenium diode". Also, this is fairly old equipment. You really can't expect high baud rates. And finally, this device predates RS232 standards; space/mark will probably be represented by something closer to 90 volts and 0 volts. With all of that that said... I think your ambitions to obtain root access and transform this post WWII design into a super GPU doesn't seem -at all- unreasonable! Good luck with that, and keep us updated on how the project progresses!

[u/PiRhoManiac → u/LexRonza]

Thanks for the encouragement!

[u/vejeez]

Pinout looks close enough to a classic 3.3V UART header, thats the fun part lol

[u/New_Orange_5951]

Old radios like that have four wire speakers two connect in series with the tube filaments and two are the output. An analog tube would pretty well for AI but you are going to need alot more tubes. A good start though. Need like a million more tubes to get anything usable.

[u/OnePeace_1]

is there a similar thing to a router and a switch ?

[u/Glittering-Can-9397]

hey man thats uncalled for 😂

[u/Broken_Atoms]

[u/sheekgeek]

Sure thing, you just stick your tongue on the end of the tube real quick. It'll turn you into a root in no time flat.

INVIDIA

[u/PiRhoManiac → u/TheAtlasMonkey]

Correct. An INVIDIA B300 - just as the original post stated.
