"nostalgia" for the old geezers

Too fuzzy to see anything.

Wow look how shiny they look, Those things must be loaded with lead.

Cheers

yeh stupid they didn't film it in full HD it is only 48 years ago /s

There is sometimes useful information in nostalgia:

I have a series of TEK booklets on video that I still find useful (my surveillance camera clients still use composite video). ...Jim Thompson

I'm looking for work... see my website.

Thinking outside the box...producing elegant & economic solutions.

absolutely, if nothing else it should put things in perspective when complaining about CAD programs etc.

Indeed! Fortunately, from habit, from about 15 years of quadrille-pad designing, BC (before CAD), I still "noodle" on paper before hitting the simulator. ...Jim Thompson

Are you suggesting that inexperience and ignorance of electronic history are virtues?

I sure don't miss tape-on-mylar PCB layouts. It could take two people two days to do the schematic-to-layout checks, like in the film. I did that so much with one young lady that we fell in love.

Some of the RadLab books, the technical summary of WWII radar development, are occasionally useful. Certainly interesting. I have the entire set.

I learned a lot by studying various Tek and HP manuals, back when they actually had content.

rather the opposite

it is something to think about when swearing at some CAD program for being clunky or buggy

I have the whole set, also.

Once upon a time ;-) ...Jim Thompson

Try that with a chip mask set. That's how I started out in 1962... multiple sheets of tape-on-mylar, stacked using fiducial _holes_ for alignment. ...Jim Thompson

Correction: That was tape-on-stabilene. ...Jim Thompson

We did multilayer boards with tape on on d-size pin-aligned mylar sheets. We cut the power pours out of rubylith. PITA.

It's much easier with CAD, but then we are doing 10-layer boards now, with 500-ball BGAs, so it's about the same PITA.

Even 35mm film is a lot better than HD.

Back in the day there was also one pretty young lady in the drafting department of my employer. She brightened up the whole room. We didn't fall in love.

Matter of fact, back in the day, whole roomfuls of young pretty ladies worked at my employer. They were hired because their smaller hands made it easier for them to stuff components into circuit boards.

Electronic magazines used to publish PCB track patterns and component layouts back then. The patterns and layouts were 1:1, which enabled hobbyists to simply attach a blank sheet of mylar over an illustration and tape away. There's a few taped mylars from the old days squirreled away in my lab for posterity's sake.

IIRC back then professional IC patterns were made larger-than-life and then photolithographically shrunk down to size. A _National Geographic_ from the 1980s shows a guy standing on his room sized IC pattern, piecing it together. The reason for using such a large pattern is unknown to me.

Thank you,

Try this if you want to be nostalgic and amused at the same time!

I hear these tran-sisters are gonna be really big someday; we'll probably be using them to talk to each other via CB radio on the Mars outpost in 1985
