Seems like it was never digitally stored in the first place, and the printed text was barely readable due to age. Not really a big win for paper.

Well it had to have been on disk or tape at some point. It wasn't all typed in by hand every time they needed to build a new version.

unless they used punch cards

Punch cards are still a form of digital storage, mind.

Also a form of storing things on paper

Reminds me of an old fortune cookie message or meme, something like "digital data is made from analog parts".

I threw out all my punch cards. Wish I'd kept at least a listing!

I find punch cards being used in old engineering books I buy from the 60s.

Maybe write them again?

> unless they used punch cards

For MS-DOS?

Not likely. Punch cards disappeared around the end of 1976.

I remember seeing stacks of cards being carried into/out of the university "computing center" in the mid 1980s, on more than a couple of occasions. Though in retrospect, these were probably just old programs that had been in various professors offices since the mid 70s, being taken to get read into some disk in the mainframe.

We still learned how to use them in the 80’s high school computer classes, mostly because we had a balance of CP/M plus card-reader/early DOS machines, eventually .. in the labs. Rich kid schools had Apples though, and some of them also had card readers for BASIC ..

"[..] card readers for BASIC"

Finally, a sensible use case for BASIC's "READ" and "DATA" commands. Learning BASIC as a kid on a micro, it always struck me as an odd way to get input into a program. Sure, with INPUT, you'd have to hand enter your input every time, but baking into the program meant that you'd have to edit your program any time you wanted to change anything.

But with a card reader, you could "cut the deck". Keep the program cards, and then just stack on whatever set of data cards you wanted.

From this vantage point, in the 21st century with our flying cars and what not, it seems really quirky that back then, even your data could be a tangible thing.

Indeed, we still pay homage to the era with terms such as the stack, pushing and popping, and all kinds of things .. i remember we had fun inserting random infinite loops in other students cards on occasion until we all realized we could just have marked “finished” stacks with an X across the spine, and also to ease sorting, and so on .. i would mark certain sub-routines with different color markers on the spine too, just to see a budget for how much computing time i expected to be billed for, and so on and on .. lots of valuable hands on came from the card-based computing, its a lost art ..

My firt job out of college in the early 1990s was at an equipment manufacturer who was still using them. They had a big chart on the wall titled "punch-card elimination" and a line trending down, but it wasn't at zero yet.

My work there was all new code and didn't involve any of that, however.

My college used them for PL/I and IBM Assembly language programming classes until 1982. Cards were used well into the mid-80s.

We still used them in the university as late as in 2010...

...as writing paper.

The idea that it never existed digitally is obviously untrue. Likely poor wording in the author's part. They probably meant something like, so old that a printout is all that survived (which sounds vaguely like not being digital to someone in an era so far removed from a time when programs were/could realistically be printed.)

Having printouts were necessary when:

1. you were using a DECwriter dot matrix printer as a terminal

2. using an ASR-33 teletype as a terminal

3. using punch cards or paper tape

4. using a glass tty that could only display 24 lines

5. when you did not have a remote terminal, and wanted to spread your code out on a table and debug it

Brings back memories of desk checking

> a time when programs were/could realistically be printed

Really depends on the program. Source code is often quite manageable. Even artifacts aren't always as large as you might expect. Busybox on my system weighs in at 1.9 MiB or alternatively 928 KiB with zstd maxed out.

But I don't really see a point to printing any of it. A situation that might require the printouts is likely to largely preclude the continued existence of modern electronics, the ability to replace batteries, or even a connection to a reliable electrical grid.

Yeah, that's why I tried to include both categories. Even for programs that are small enough to be printed, we just don't do it any more. I could have worded that part better myself.

Early versions of some things, MS Basic being one example I think, were baked into ROM. One of the best innovations that Paul Allen came up with was adding software hooks to the code so bugs that were found later could still be patched.

How did they print it then, I wonder?

They had some old German guy with a big beard, and two interns, running some sort of big contraption that looked like a medieval torture instrument, and the interns would run and put letters in a row and then the old guy move a massive letter and in the end out came a bit of paper with source code on it.

I appreciate the subtle sarcasm, I did not consider a printing press as an option!

Where can I buy this printer?

Humbrechthof, Mainz, Germany ofc.

One has to be pretty ignorant and dismissive to claim that this is not "a big win for paper".

First of all, that comment is weirdly out of place. The quality and longevity of paper is not the topic.

Secondly, there are fragments of paper with writing as old as 2,000 years.

Thirdly, paper you look at and see the writing. With digital documents, you need the technology to read the medium and then you need to know how the information was encoded onto the medium, before you even arrive at the same level with paper, where you can start to decide the actual writing.

Paper has brought us where we are today, and given us what we know about the past. Don't be so ignorant and dismissive.
