Thanks! Comment from : Douglas Schaefer

While this comment is now 10 years old as I watched it, I feel that I should make this comment… my purpose is to demonstrate just how fast computer technology has progressed since these boards were made (and, yes, I was around back in ‘63…) I watched this on my iPad computer which is 024 inch (635 mm) I’m still reeling from the implication Comment from : Bill Daniels

You need to talk to Destin over at Smarter Everyday He's got great contacts at NASA that would know all about that board Comment from : RandomTorok

damnnnnn i am in loveeeeee uu Comment from : ASMR Art (asmAr-T)

Beautiful finding, sure this was the father or the grandpa of the SMD technology, but these circuits weren't not commercial???brGreetings from Brazil!!! Comment from : Luiz Marxsen jr

oh my she has always been cute Comment from : Fuck you

Muito bom , parabéns , gostaria de ver estas placas de perto, uma parte da história brParabéns em apresentar Comment from : Joel Macedo

Damn! Fran is smokin hot !!! OOw oooooh!! sorry Comment from : Richie Bricker

I have seen similar boards or very similar ones, either at Radio Rally meetups in the 1970' and also in Computer museums There is a very nice museum in The Netherlands that used to have some examples I believe At some point I had a computer systems design manual that covered many exotic architectures from the era, sadly long since gone I think it was either Wiley or Prentice Hall Just did a search and found a very nice blog post on Ken Shirriff's blog with a lot of info and plenty of links relating to the LVDC designsbrbrIt really is amazing to see the board, and crazy to think about the design and engineering that went into itbrbrThank you for showing it to us and a very nice channel you have here All the best Comment from : Jumpstar

Hey classic Fran! Comment from : Mister Sid

I’m going to keep an eye out for that board on the eBay Comment from : CatLady

My number 1 nerdy chick on youtube Comment from : Qthulu __

Progress seems to come in jumps and motivated by conflicts or crisis Amazing to see that board in your collection Thanks for sharing Comment from : Henrik Morsing

Looking prettier and pretty everyday Comment from : Bryan Contreras

I imagined that LVDC board to be about two technological steps before the single-IC microprocessor Comment from : Floyd Johnson

THIS ASIDE FROM ALWAYS VERY INTERRESTING TOPICS AT " FRAN LAB " (I PREFER YOU BLOND FRAN IF YOU DON;T MIND ME SAYING ) Comment from : Frank Cole

Such a beautiful beautiful brbrbrBourd Comment from : rcorn149

Hi Fran I really like your videos Thanks for sharing this Comment from : William Pezzner

Friend what a great video 8 years ago wow you've been doing this for a long time hun that's amazing I looked well I fingered I checked to see how all the video was cuz I didn't hear you're really great guitarist which I look forward to the end of your videos thank you again for this video I learned a lot I love things like this I love this type of knowledge and this type of video so thank you for the content keep going on 8 years wow PS excuse the Huns they are not the they were not necessary meant no disrespect just my old days sincerely yours, above the flying fishing guitars Comment from : Bob the blind bedroom guitarist guitarist

I think you are so pretty Dreamey Comment from : Glynn Phillips

I love Fran and I don't care who knows it Comment from : Alfalfa Male

is there any piece of tech from it, that is sine qua non for the entire board here? and who made it where did it came from? I wonder if we can trace some of the key techs that made the difference and where do they lead Comment from : Paul V

How Impossibly Cool-that you have this incredible piece of history!! Fran, your deep knowledge with respect to this and the nature of what it is that you hold in your hands, transcends any notion of entertainment You are expounding on actual digital history As someone who has taught computer science, mathematics and such at several universities, you make this stuff the kind of fun I wish I could have exposed my students to!! Comment from : John Kormos

Now I understand from where they got the inspiration for the character of Kaylee Frye from Firefly Comment from : samantha qiu

Nice Comment from : Anton van Haasteren

dang ur cute here! Comment from : James Price

Uve herd story of first semiconductor? STory is they pulled the chips off the rosewell crashed ufo, THEY figured out how to reverse engineer, but kept BLOWING them up, ive heard rumor that for a lifetime supply of Krispy Kreme doughnuts, the aliens toldem @ the CLEAN room Comment from : James Price

Looks like the aliens gave USA a gift card! :) Comment from : James Price

What a gem ! Comment from : Sergeant Crow

it is so empowering watching you be so smart and understated and just awesome… makes me happy Comment from : carlaK

You can go to a grist mill in North Carolina ran by Jack Dellinger He and 6 or 7 engineers made that working for IBM I met him 2 years ago He was hired personally by Von Braun to be on the Saturn development I kid you not he makes grits at his family's mlll they have owned since the 1800s in his retirement A boy from Appalachia help design that baby Comment from : Left Hook

Your amazing Comment from : mike kowalski

wOOOOOAH that's awesome <3brHUMAN ACHIEVEMENT Comment from : Ars Aeterna

I don't care how old you are fran, your a fox! Comment from : James Sheehan

You're very fun and smart Comment from : Hunter the Parmesan Cheese Smoker

Wow your hair Comment from : Hunter the Parmesan Cheese Smoker

All these comments commenting on this computer board, which is no doubt history, but failing to see that you are soooo hot, especially with the dark hair and classic nerdy glasses Perhaps I wouldn't be feeling so amorous had i not seen your vid with swamp ash tele, complete with benders And to think you built it! That is where you had me, hands down!! You see, I am sitting here staring at a tele I am building for the surgeon who did my back surgery, and I am thinking "I don't know crap about science" but this girl makes it interesting, and she loves Teles!!!! Comment from : Ken Russell

They say we lost the technology to go back to the moon Maybe we need to slap that back into our rockets and we would be A-OK again? Comment from : Stronger & Wiser

That's so mind blowing to think that little thing was absolutely instrumental in space travel brbrMagnificent Comment from : Dolphin

Looking so young🤩 Comment from : M Talha Khalid

What if Apollo Saturn V would be launched using electronic tubes digital computer?!! :)) Comment from : EmilMarius1960

That is neat Comment from : John Gormley

How is your LVDC project going, Fran? Comment from : Nicholas Maude

Hi Fran,brI worked for IBM in the early seventies, and a good friend and colleague of mine worked on the LVDC at Cape Kennedy He said he knew they were serious when they brought a cot into his office BTW, the flip chip technology is called controlled collapse chip connection, or C4 for short Comment from : By Wire 1964

Here you gobrAt&t tech channel is for youbrRope memory Who made all of this?brThe TELEPHONE COMPANYbrNo ca-cabrWestern Electric IS a major part of the NASA structurebrAt&t tech channel has videos about how these parts were made They should; George Kupzack is waiting to walk you through the advancements that made the bell system as stout as it was Satellites were first constructed and launched at NASA facilities by whom?brWESTERN ELECTRICbrLook & see 😘 Comment from : Majik Glustik

looks like a processor that you could control how many threads which would be kinda pointless but i'm not a expert on that stuff Comment from : Bo Huggabee

Those 400 billion dollars spent on apollo program in 1960s were possibly best spent money ever by government, so much industries and companies and tech superiority, research progress from that not even universities have that effect despite quite big funding through decades Comment from : effexon

Were soviets ahead in electronics during that 1957-1969 period or did they just rely on "manual tech" more? 1965 Korolev died so that was there hindering development, other than that they had pretty solid rockets early 1960s Comment from : effexon

Hi Fran, I am Michael I am new to your site love it, thank you for all the cool gear😎 Comment from : Michael Sinclair

That is oddly advanced Comment from : TestTubeBabySpy

Hello Fran, I worked at a large aerospace company for 43 years one of my best memories was working on small circuit boards out of the F15 RADAR I have spent many hours soldering(repairing) Flat Packs Yes, the boards were plated through and had at least 8 layers BUT when the board broke due to flexing or heat issues, the plated through holes(traces) broke and I had to solder TINY jumpers to various points on the board to pick up the missing tracesThis was back in the 80s It's fascinating that the technology was for this type of computing was invented for the space program 15 years earlier AND we still use the same technology Comment from : Mike Rootz

How have I not seen your channel sooner, you are so awesome Comment from : Xan Bell

Can you provide also some more infos on the DTL logic board of Gemini missions? Thanks a lot for your video! Comment from : Eduardo Rossi

Tech history awesome glad I subbed your channel Comment from : Fuzzy Lumpkin

Fascinating piece of history! Comment from : Bill Steedle

Forget about pearls or perfume A gift of a circuit board is the way to Fran's heart Comment from : Jun Gleno

Incredible, I didn't know SMD already existed at that time At same time they were still using magnetic-core memory Comment from : marcelorsc

cool franbrwhere have i been Comment from : sparkyindahouse

such a hottie with that dark hair! Comment from : J Mason

Nasa found out tiny connections between SMD start growing "whiskers", they kind of look like a crystals but are actually pretty conductive which makes them dangerous because of shorts, unwanted connections, etc Even satelites have fallen to earth because of this I'm not sure what they use now, maybe different solder composition Comment from : Coda Alive

Oh wow, I'm impressed 👀👀👍 Comment from : Jaroslav Henzely

Hay Fran Comment from : Steven Long

What is the meaning of this video? Comment from : Ricardo Bonelle

The corners of the tracks are now 45' to reduce the inductance by a few tens of nano-henry's I used to track boards manually using crepe tape and scalpel There were 2:1 sticky IC footprints, dots for vias These were stuck to a clear stable film and I did two layers by using two films plus film for the silk-screen Comment from : Andrew Lohmann

hi fran nevin from calf like the stuff had a tip you probably know the halogen lamp puts out radiation that melts salder Comment from : Nevin Loop

Solid state master piece Comment from : James Lane

I had no idea that surface mount technology went all the way back to 1965!brI thought it started sometime in the 1980's Comment from : maddogmcrae

Fran is fantastic, she knows her onions about all things computerish Comment from : Team-Fabulous

Beautiful woman you are fine😘😘😘 Comment from : Bryant Whittaker

God your beautiful Comment from : Jon Chapman

Computer powered eyes Comment from : Bhadra News

So this video just appeared in my recommendations Thanks YT brSee Curious Marc's channel for a series on rebuilding the AGC Comment from : Christopher Lawley

Fran, I graduated in 1969 BSEE specialized in logic design A technique that was used at the time was to use logic nand, nor, and invert gates on the PCB and wire them into a functions like Flop flops, counters, shift registers, etc on the backplane The board you show is likely of this type Hard to know without a schematic I know that the Cray supercomputer of that era was built in this way Comment from : charles vanberg

Anyone ever tell you your hot? Comment from : Cliff Ransome

Whotomadevideo Comment from : Deepak Majhi

It's amazing how fast technology moves when the stakes are high The space program and even war pushed technology to the cutting edge but that hasn't happened in a very long time I wonder if we are lagging behind were we could be now Comment from : Woogoo336

Sounds like a job for curiousmarc !! Comment from : Shamrock

hold up This isn't Curious Marc :D Comment from : rkan2

"This is the mother of all modern computing boards, and largely forgotten" Great comparison to the ArduinobrbrVery curious how you got your nitrile-encased paws on those historic-vintage computing boards!! Comment from : KP

Wow! Comment from : Paul Petty

Wow, I hope you follow Curious Marc and his Apolo AGC recent restorationbrSo little is known about the LVDC, thanksbrAlways great Fran! Comment from : Eric Girard

Yes, but will it make a good distortion pedal? All kidding aside, how did you get your hands on such an interesting piece? Comment from : Ric Cortez

Where in the $#@ did you get your hands on that? Comment from : Carl Franz

I realize this video has been around a while, it is nice to find it The Saturn's were the heavy lift for big payloads I worked on some of those and am happy to see you show one of the boards of that era It is important to talk about the durability of the build The vibration and stress of a lift off could be catastrophic for many materials When you look at the board you see special soldering and heavy duty chips If that board was a spare, it had undergone a lot of test time to ensure the parts and build could survive launch You have a very special piece of history Comment from : Buena Ventura Life

I agree , this was very modern: surface mount, multi layer Comment from : Bernd Grabitz

no entiendo quien se cree que la ciencia es de mojigatos Comment from : MGC
