1976 PCB design at CERN

It's amazing what we take for granted these days:

“Quest” for printed circuit boards 😉

In 1976, CERN activities required a growing amount of printed circuit boards, so the Laboratory acquired Quest systems to automate their design and production.

As you can see in this #ThrowbackThursday, each system was equipped with a digitising table, a teletype, a computer, a pen plotter, a perforator and a photoplotter, so that the user could guide the machine to drill holes in the boards.

Guess how much faster it was to make printed circuit boards using these machines?

Well, what to do if you need "Ctrl+Z"?

Based on my experience this year trying to learn Cadence PCB design and schematic tools by myself at home in lockdown so I could make some 8 layer boards for CERN, I think I'd rather have used this!  :D

Are we forgetting that KiCAD is supported by CERN?
Or do they not use it internally?

"Guess how much faster it was to make printed circuit boards using these machines?"

Well, what to do if you need "Ctrl+Z"?

Altium has plenty of CTRL-Z support. I used Orcad for a couple of years in the mid 2000's, and it had only one level of CTRL-Z on the schematic layout. When I asked Orcad support why don't they put support for in several undo's, his reply was "There is no market need for it." :-// Orcad did have a superior (simpler) component library management system to Altium's dog's breakfast.

Have they since fixed their component library or is it still the same?
I ask because we had a PCB design course at university two years ago and had to use Altium, and working with component libraries was the biggest pain in the ass.  |O
Meanwhile i use KiCAD for my personal projects and for the most part i can just throw anything at it and it just worksTM:D

Outstanding...

I just love  that VFD (looks like a VFD)  panel over there...

At 70s that stuff was state of the art..

This is a very cool setup. Although more modern, this reminds me of the first computing trade show I attended at the age of 10 or 11 in mid 80s. One of the most impressive things I recall seeing were Sisgraph CAE/CAD/CAM stations that had incredibly advanced graphics - all that tied to 16-color plotters with those tiny pens drawing on A0 papers. Great memories!

Oh, the "whys" of the datasheets... The information is there not to be an axiomatic truth, but instead each speck of data must be slowly inhaled while carefully performing a deep search inside oneself to find the true metaphysical sense...

I did use a similar minicomputer system by Computervision. Totally outer space in the era, I was in awe every time I used it.

I think it was Compucircuit for PCB CADD on CADDS 4 in the early 80's, with a Calcomp and a photo-plotter for near instant artwork. 16-bit minicomputer I think Data General, 19" Tektronix colour CRT, had a near "washing machine" HDD.

Fundamentally it was all command-line driven, object-oriented using noun and verb statements, none of the crap you see today. The PCB layout was manipulating entities within a database. In that sense it was actually quite powerful, you just had to compose the command and it would do it, no questions asked. Not a great undo feature though.
The digitizer pad was inductive. Pen presses were all macros, so you could program anything you wanted for functions.

The government had bought it for local university $250,000 also for doing IC layout, back in the day to grow technology, big bucks. But the system was massively overpriced. The maintenance contract alone was so expensive the university couldn't afford upkeep/updates so they orphaned the system. It came with no UPS because of the cost, so a thunderstorm was really bad for it, AC mains glitch and it would get scrambled and revert to tape backup. That part really sucked.

There was a CADD boom in the 80's and then the bust.
