There is an interesting history to the fax:

Alexander Bainis credited with inventing the first technology to send an image over a wire.
Alexander Bain, Inventor of the Fax
Alexander Bain, Inventor of the Fax
Working on an experimental fax machine between 1843 and 1846, he was able to synchronize the movement of two pendulums through a clock, and with that motion scan a message on a line by line basis.
The image was projected to an from a cylinder, and while it was able to transfer an image it was of quite poor quality.
Bain’s patent, dated May 27, 1843, was for “improvements in producing and regulating electric currents and improvements in timepieces, and in electric printing, and signal telegraphs”
My father taught me to use a slide rule when I was in grade school probably around 1970. Told me I would never make it anywhere in life without knowing how to use a slide rule.
$30 at Office Depot. Also functions as a copy machine. B&W laser print. Of course, the real cost is the toner cartridge.
During my 30 years working in various offices, faxes ended up at a wrong place at our end or the other end all the time. I despise fax machines!
I know how you feel about that cost-per-byte issue. I remember when a 80 megabyte 8-inch Winchester drive was close to $2K. Well, a tiny IBM 1130 computer system cost $120,000 in 1967 money; and, that had a 16K byte core with a 1.5 megabyte disk!
I think you are right. Drum scanners were also how most newspapers prepared plates for printing pictures. The big boys acid etched metal plates using halftone screens.
I had to look it up to... but when I think fax machine, I think about how it scans an image (even if the image is text on a document) and sends that image to be printed again. I wouldn’t think as an electric telegraph machine as a fax, but it is in the same family.
The ENV3 has a full keyboard. Love it.
1.44 floppies may be primitive, but they are not likely to ever become completely obsolete.
There are many old but never replaced software packages that require them to operate.
The software industry seems to lose interest in certain areas, and never offer modern updates.

>> “I’m obsolete technology.” <<
Are you saying that you now have come to believe in evolution? (snicker)

Correct answer !!
“Take it from an old stew burner”
Hey, ol’ stew burner.....! ;-)
I’ll try to tell you in simpler terms which you might be able to understand:
It is not the low frequencies or high frequencies which are necessarily affected or lost.
Digital music, a music CD for example, samples the sounds it ‘hears’ at the rate of 128,000 times per second - meaning that any sound which happens between each ‘sample’ is lost and is not recorded.
To put it in more usable frequencies - let’s assume that the sampling rate is 2 times per second instead of 128,000 times per second. All sounds between the 2 times per second samples would not be ‘heard’ or recorded, regardless of the frequency of the actual sound.
Vinyl does not do that. Vinyl is analog and records all sounds and, depending upon the quality of the sound equipment, can ‘hear’ 20 Hz to 20 KHz. A CD claims to ‘hear’ all of those frequencies but, again, they are sometimes ‘muffled’ because of the sampling rate.
I hope that I did not confuse you!
Maybe you could think about it like this:
You sample your pot of stew 128 times over a four hour period, for taste.....OR.....you sample your pot of stew 2 times over a four hour period, for taste. All of the changes in taste that happened between your 128 ‘samplings’ or your 2 ‘samplings’ would be lost, right? Agree? I like to cook, too! LOL
“Saw the last reply was to your post so had to answer.
Agreed. I’ve always thought CDs are heavy on the treble side. And your analysis makes sense. We think of digital as superior, but it works in 1 and 0. Losing all the fractions in between.”
The only knock on vinyl is that where there is friction there is noise. The friction between the cartridge/needle and vinyl does create noise.
The advantage of CDs is that there is no friction because there is no physical contact between the CD an laser sensor and therefore no noise.
It has become a toss-up as to which one prefers.
Had to give that up too, loss of taste, sucks to get old.
If your family members don’t want or appreciate your turntable, put my name in your will. I’ll be elated to receive it!
What era is the vinyl from? If it’s doo-wop, early R&B or classic country, will those to me too. I can guarantee they will be played and enjoyed. :)
Guess you’re right. There were many things we knew how to do but couldn’t make mass produce-able until the transistor.
