Vintage technology and why some people still use it

It makes me sad because we have the technology and resources as an industry to make so much better products than ever before, but we just don't focus on quality for the consumer anymore. Can we collectively care to do better?
Today main product design drivers are collecting usage data and selling it to advertisers, enforcing dependency on cloud services, preventing repairability and ownership (vs. ongoing licensing). All these factors improve recurring revenue for the producing company but all of them are anti-features for the consumer.
All my cars are older and will forever be. No TV screen on the dash to go bad, no integrated CAN bus making diagnostics and repair a nightmare, no fly by wire nonsense. No phone-home spyware or OTA update horrors. If a relay goes bad it's a physical relay I can swap, easy. And so on, everything is fixable.
I unpacked my old Wii to play with my son. All the games are on DVD, so I own them, they won't disappear from the cloud, no dependency on internet connectivity, no subscriptions to pay.
For music in the house I run many squeezebox devices. The server is self-hosted and open source, no dependency on anything external, no subscriptions or cloud service to be suddenly cancelled.
Fuel efficiency is worse in older cars:
https://www.bts.gov/content/average-fuel-efficiency-us-light...
So are emissions:
https://www.epa.gov/automotive-trends/highlights-automotive-...
Safety standards, too. All of those things are quality benefits for the median consumer (who doesn't even know what a CAN bus is).
But the emissions footprint in producing the new, fuel efficient car to replace your old one is quite staggering
But if you compare a new 1998 car to a new 2018 car of the same class, the 2018 car is absolutely going to be better on fuel efficiency and emissions than the 1998 car. And it's not like they got better at fuel efficiency and worse at user maintainability for entirely unrelated reasons; sticking little computers and sensors in things like the fuel injection system is why they're more fuel efficient/better at emissions. (Yes, the little dashboard display is not saving you anything on fuel, it's not 100% related, but they're not fully orthogonal issues either.
I have a 1985 VW van, so it's haha the wrong direction for me.
Cars are insanely expensive here, and at 150.000km the car isn’t really in need of replacement. Doing so would also be more environmentally damaging, compared to driving it less than a 100km per week.
For a concrete example, a 2021 Toyota Camry Hybrid at 52mpg emits 170g/mile of CO2[2]. A 2000 Camry 4cl at 24mpg emits 340g/mile[3]. Assuming you drive an average 13,500 miles/year[4] the break-even point for CO2 is about 4.5 years.
If you have the 2000 V6 Camry at 20mpg then the break-even is closer to 2.5 years.

Also fixing, improving: you gain that knowledge for yourself and share it with others. Instead of remaining a one-trick-pony. How many people even know how to change an oil filter? Hell you may wind up paying someone to change your battery. How crazy is that? Winding up tightly dependent.
You can of course always pay for service if you don't feel like doing it.
But that's missing the point. With older cars you have a choice of DIY or pay someone.
With newer BMWs or example, even something as trivial as changing the battery requires dealer intervention because the ECU is coded to the battery (for no reason whatsoever, other than proprietary lock-in).
Today, there are still independent BMW-certified mechanics who have access to the proprietary tooling to do these operations so if you make friends with one, you can still change a battery yourself. But nothing prevents BMW from cutting them off someday and then you're truly stuck with a dependency on the dealer. And what happens when BMW decides your model is no longer supported because they want you to buy a new one?
No thanks. I'll have older cars which can be fixed mechanically without any DRM nonsense.
Are we talking about secondhand owners? People who buy BMWs don't have friends.
In that case I feel for them, but at least there's plenty of other (generally cheaper and more reliable) brands.
On fleet-wide average, for sure. But not for all cars.
One of my cars (daily commuter pre-pandemic) is a late 80s Honda CRX, it gets nearly 40 MPG. Even in 2021 many (probably most) cars can't match that kind of efficiency.
(Energy cost per mile is lower than for my partner's electric Fiat 500e!)
The car that makes me sad and almost angry is the original CRX HF (mine is not an HF). This is a car that got over 50MPG with mid-80s engine technology!
https://jalopnik.com/1986-honda-crx-hf-393147
If Honda had continued developing the HF engine, what kind of mileage could an evolved 2021 CRX HF be getting today? We'll never know, but I'd guess over 70MPG.
As a ranty aside: You are not safer in an older car because they usually have lousy side-impact ratings. Also, the cyber-security issues of newer cars are overstated. While new cars have many computers, outside of what's in the head unit these aren't general purpose computers, but rather are running code bare-meta, don't communicate on anything other than a can bus or i2c and follow a decentralized architecture. Car manufacturers are extremely conservative in their designs. There have been documented issues like the Jeep Cherokee head unit being able to send arbitrary messages over CAN via the head unit cellular link but but all current car models have telematics.
Or you have one of these cars with sensors in the windshield to detect other cars on the road and your windshield cracks. That’s going to cost a hell of a lot more to fix than a regular windshield.
I believe the "latest technology" today, as in the stuff discussed on HN, is often less reliable than what came before. Convenience is interesting, but if asked to choose, I would choose reliability over convenience. I also fear that younger generations are being conditioned to accept lower threshholds of reliability.
I can see some of the blue areas banning all sorts of things, but the red areas wont, and there are constitutionality issues with trying to stretch the commerce clause to things like forcing states to ban certain types of technology. Even the Federal highway speed limits have been a constitutional nightmare and many states no longer follow the national speed limits, which were also designed to improve on fuel economy and reduce emissions (e.g. https://www.newsweek.com/kentucky-judge-rules-states-speed-l...)
I have been tempted to get an emulator console, but they all have brighter, higher resolution screens and shorter battery lives, so I don't actually know if I'll get in the same "flow". Maybe I'll reassess after I finish this stack of JRPGs (which may take a decade).
Once everything became "connected" (around 2010), obsolescence became inevitable. That Psion5 or Zen Stone can remain timeless because they will never sync a contact list or download a patch. The owners know what they do, and seem confident that they will not fail.
I’ve found so many fun arcade games that I never had a chance to play in a real arcade as well as galaga and other classics. Highly recommend!
You will need a drill with a 1 inch wood bit to make the holes for the buttons.
Hope that helps!
Almost all of my old household appliances included schematics, but new stuff only includes operational instructions. It makes me sad we have lost this culture of tinkering.
“flight proven”
Despite being nearly half a century old and an uncommon design it was literally an afternoon to get it up and running again after it'd spent over a decade in my neighbour's garage. Ridiculously well made bit of kit.
If anything its even easier now because its dirt cheap and there are hundreds of hours of tutorials available for free. And the arduino tools have removed a lot of the pointless complexity like telling your compiler what clock speed and revision your chip is.
Not quite. You are programming the Arduino, but you are using a vastly more complicated computer to do it. There is a lot of beauty in the simplicity of having a machine simpler than an Arduino and be able to, using nothing but it, get an interesting result.
If you wanted to make a mixtape, you had to record each song one by one in your CD-Cassette combo boombox. The last Walkman I owned was in 2001. After that it was all discman players and non-iPod MP3 players.
I still have relatively strong memories attached to each of them as they were permanent fixture on my person prior to smartphones arriving. I've tried to recapture it on my Neocities page here: https://bad-mood-rising.neocities.org/mp3.html
Even a small amount of extra effort in the correct places makes a lot of difference.
I still use Eclipse, btw.
And I don't mean stop inventing new things — I mean stop using stuff without understanding how it works under the hood. Stop embracing that kind of thinking and lowering the barrier to entry by wrapping everything into layers upon layers of "simple" abstractions and making it obscenely inefficient in the process. Stop "moving fast and breaking things". Stop making everyone think that software sucks, that that's its default state. I hate this "developer time is more expensive than machine time" saying. And there's no "premature optimization". Performance isn't a feature you can add at a later date whenever you feel like it — it's a function of the overall design of your product.
Also, I can't help but feel like most of programming these days happens for the sake of the process itself, and the resulting product is more of an unintended side effect.
> and play games in DOS
Not necessarily a bad thing tbh.
Where the healthy middle point lies is something I don't know.
Got it at a garage sale for a song in the early 1990s.
Given away since. I don't do stereo components any more, just listen with bluetooth headphones from a smartphone like everyone else.
Believe it or not stereo systems are still frequently purchased even in 2021.
Never again.
All my music collection is FLAC files, bit-perfectly ripped from my CD collection. So, sure, they're digital files, compressed, but lossless. It is, for all practical purposes, just as good as a CD (as long as my external DAC is as good as the CD players' built-in DAC).
The original CD may have been badly engineered but that's another topic.
3 000 CDs fits in more or less 1 TB in lossless (but compressed) CD quality (just to give an idea of how tiny it is using modern storage standards).
Some people only use FLAC as archives but these files are so tiny in this day and age that I don't bother converting the FLAC to mp3s: I sent directly the bitperfectly ripped FLAC files to my DAC / stereo setup.
CDs in a player always have errors. The errors are covered up by a couple of stages of error correction. One is a transparent CRC, the other drops the effective bit depth down to 12 or so bits.
The Block Error Rate (BLER) on CDs can be surprisingly high. So a CD in a player is always slightly compromised.
When you rip a CD with a good ripper the drive does multiple passes over problem areas until the results are consistent. The final file is bit perfect, except on very damaged CDs.
You must mean CIRC. CRC in the context of errors is something completely different. CIRC offers pretty good error recovery, so except for bad scratches, CDs and FLAC (assuming it's also 16 bit, 44000 Hz) are identical.
MD players generally have VU meters, and you can observe your music, since they generally have recording functionality and used in studio and/or interviews, getting sound as transparent as possible is the aim.
Fun fact: Portable MD players are generally called "Portable MD Deck" by Sony to signal it's not a mere player but an audio equipment. Most MD decks contain indexing and primary tools for chopping a record to tracks and tagging them.
There is a rare variant called ATRAC Advanced Lossless but it was never available on many devices.
ATRAC is of course lossy and compresses the audio. The compression I mentioned was loudness maximizing/homogenizing compression which is used in mastering process, or in audio pipelines in general. So we can say that, ATRAC is devoid of any compressor stage which makes the resulting audio more loud by default.
That loudness maximizer/equalizer also called compressor so it's easy to misrepresent or write misinforming things when talking about both at the same time.
Sorry, my bad.
First of al, ATRAC is a strange format. It's optimized for perception as far as I understood it. It doesn't color sound but can reproduce the dynamics and details very well. It's important to understand ATRAC has quality levels: SP, LP2, LP4. SP fits 80 minutes to a 80 minute MD. LP2 fits ~160 minutes, LP4 fits ~320. SP is extremely detailed and transparent. LP2 is really pretty good. LP4 is not good. Is not bad, but for listening on the move. It's not suitable for joy-listening on higher resolution systems. The deficiencies will be definitely heard.
This sound quality has another reason. The DSP/DAC combo on MD players itself. Earlier versions were called Type-R, improved versions are called Type-S. Latter one can reconstruct sound very impressively. It can make SP and LP2 sound really good. It also has a digital amplification section. So, It's only converted to analog at the latest stage. Result is a very dynamic and clean sound. Especially if you convert to ATRAC from CD or any lossless source.
My Hi-Fi (Sony CMT-HX3) also has a 35W version of that DSP/Amplifier combo. It really sounds fantastic* with CD, MP3 and AC3. Didn't try ATRAC, but it won't disappoint I presume.
Sony's higher end systems and DSPs are a work of art. They sound clean, crisp and detailed. They can sing through a pair of good headphones or through 2x85W behemoths. This is why they're timeless and regarded highly. With just Bass & Treble settings, it beats a lot of presumably higher end portable players.
A similar sound quality was present in Creative's Muvo^2. It was plain enjoyable to listen. Apple's iPods famously use Burr Brown DACs but, the sound was too flat and dull in the earlier versions, lacking punch and energy. They fixed it after iPhone 5.
TL;DR: Sony's DSP/DAC/Amp stuff makes any well designed audio codec shine. ATRAC can store dynamics very well. This is why being a Hi-Fi company pays in the portable space.
*: I have a more conventional, but vastly higher powered system. This small guy is not a match for it, but for a small hi-fi it really hits above its league. If you scale this design up (to 80+ watts) with proper speakers, I'm sure that it'll make a lot of more expensive systems sweat.
On the paper and spectrogram, an SP ATRAC track is not a match for WAV or FLAC, however it has all the ingredients to saturate a high-resolution system and create an enjoyable listening experience. Also it had enough resolution to handle higher-end amateur mastering (in SP mode) and general recording needs (in SP and LP2 mode).
While 44.1KHz is perfect mathematically, 48KHz and 96KHz can create a smoother sound. That needs higher end equipment to hear clearly, but the smoothness is definitely there.
I would really encourage blind testing of one's assumptions about audio quality. Foobar2000 has this super nice ABX plugin that can handle automatic conversation to different codecs and or PCM sampling rates and depth from lossless sources. https://www.foobar2000.org/components/view/foo_abx
I can personally recognize full bitrate mp3 (this ancient codec maxes out at 320 kbps where it still sounds colored). This is a well-made pre-configured test https://www.npr.org/sections/therecord/2015/06/02/411473508/...
But move on to anything more modern than mp3, such as Apple's AAC encoder (there's a ton of bad AAC encoders out there) or Vorbis with VBR settings averaging at 256-320 kbps. You'll find it very hard to spot the lossy encodes in a blind test. Opus is astonishingly good at even lower bitrates.
I really challenge you to reliably detect the lossy sample in the tests for Apple iTunes AAC ~256 kbps and Spotify high quality. http://abx.digitalfeed.net/list.html
I'll take a look to it, thanks for the link. That sounds interesting.
> I would really encourage blind testing of one's assumptions about audio quality.
I'd gladly take an ABX test and stand corrected. digital feed's ABX test is pretty good but needs some quiet time to do it correctly. I'll try to find some time to take it. I tried but, it's not good when you don't have time.
> I can personally recognize full bitrate mp3.
It's possible to recognize some equipment (software or hardware) by ear because of its distinctive sound dynamics. I've listened a limited set of stuff (amplifiers, headphones, CD players, etc.) and can recognize each of them by ear. I think starting early and playing some instruments in groups help with ear training.
> But move on to anything more modern than mp3, such as Apple's AAC encoder...
The latest generation of encoders sound extremely transparent. You're right about it. It's a good thing actually. I'm not grumpy about not being able to brag about identifying the codec of the file I'm listening to. I just want to hear enjoyable, detailed, high resolution music. If my ears and brain are happy about what they're hearing, I'm happy.
48khz vs 44.1khz has the same sound quality in the human-audible range (maybe not if you're a dog); the actual reason DVD is 48khz instead of 44.1 is that it syncs up with 24fps frame rates better.
After a certain point, yes. I'd personally wouldn't distinguish a %0.001 THD Burr Brown DAC and %0.0001 THD Burr Brown DAC in normal listening volumes with a good amplifier and set of good speakers. I inadvertently own both variants (one is in my CD player, the other is in my sound card).
However, being a former orchestra player, I assume I can hear a really bad DAC and a difference between 44.1KHz file and 48KHz file under some circumstances (like high detailed cymbals or other sounds in treble range). I'll happily stand corrected though.
ATRAC is not optimized for anything that other codecs aren't (and technologically it's quite bad, especially compared to Opus but even compared to AAC). And there aren't magically better DACs any more than there are better power cables; they're all good enough as long as they're electrically compliant with your headphones.
That's of course fair. I can't ship you my MD player (that thing is priceless for me), but I can share a triplet of files for ABX testing. If you wish, I can do the following:
- Rip a track from an album before loudness wars began to FLAC.
- Rip the same track with Sony's own MD studio to ATRAC SP.
- I can re-encode said ATRAC SP track to FLAC.
- Ship you three files (A, B, X) where A is FLAC, B is ATRAC SP and X is either of one.
If that's OK for you, I can do it this weekend.I'm not claiming anything or hoping for any outcome. My aim is to test, discuss and broaden my mental horizon. I've written these things by listening same stuff in many formats through the same audio pipelines (audio cards, Hi-Fi systems and speakers/earphones) for many years and, I instinctively know how every one of them behaves with any combination. Also, I've played in orchestras (big bands and symphonies), so my ear is somewhat trained to find nuances.
Making the some tests and discussing these things will only make me happy, and I'd gladly stand corrected.
Thanks.
It won't always be transparent so the ABX test should still be passable on extreme content, but it'll sound good enough. Anything else would also sound good enough though.
> Also, I've played in orchestras (big bands and symphonies), so my ear is somewhat trained to find nuances.
How's your high end hearing? It tends to go once you're not a teen…
It can go up to 352kbps as Sonic Stage tells me. Will transfer one album to my MD player to see how it converts it to ATRAC. SonicStage rips your CDs to ATRAC3 Advanced Lossless by default and re-converts them to appropriate format for your device during "burning" it to your MD player. I'll use the files transferred to MD for ABX test.
> How's your high end hearing? It tends to go once you're not a teen…
I assume it's not bad. Can hear pretty silent stuff pretty well, including very high pitched adapter noise (not the capacitor whine, but the switching noise of the adapter itself, the one supposedly bothers dogs).
the only stuff i've heard that was recorded by amateurs that comes close (and possibly surpasses, depending on who's running the conversion / editing) is DAT recordings using the microphones shaped like a human head, for "perfect" stereo separation.
anecdotal, for sure, but the "compression" - ATRAC - was extremely good, especially at that time. I am aware that CDs have "no compression" on the data, so obviously DAT -> CD would sound better than MD -> CD, but this is my opinion.
They still are great machines today if your main usage is an ide, browser and video.
Don't get me wrong, I love my new mbp, but, I don't see any true difference in daily usage besides weight, and screen resolution.
Edit: I drive an '85 VW Vanagon camper with the original 1.9L motor, fuel injection, and control system that lacks OBD2.
I drive classic cars (under 3k yearly) and every trip is a delightful. No distractions, no absence of control. Craftsmanship and quality of materials.
Driving Electric cars will be mandatory, I plan to convert my classic cars. No tracking, no data gathering and corporate overlords for me.
Today there are more scene releases for C64 than for any other device, including PC.
AFAIC Apple 1 & 2 where just prototypes for the final 8-bit computer with SID (audio) and VIC2 (graphics) chips that blew everything else away until 16-bit!
Maybe not to that extreme but you’d be surprised how many industrial machines still running on early OSes and even with CRT monitors. If it’s not broken don’t fix it.
It was horribly dangerous but still nobody seemed to get hurt.
Enough current to explode one’s innards in two wands you just go and touch ground pathways to make sure they don’t leak on high voltage/high current portable distribution terminals and lamps.
That job was a really fun experience.
I made some fun games in OPL. It was a really wonderful basic variant, perfect for the device.
You also don't need 5nm processing nodes to remake them, even a 130nm would be an improvement, and I have the feeling that even on 40nm there would be ample fabs able to make them.
It's probably more difficult than I imagine, and less efficient than just replacing the whole system with a FPGA.
Imagine if we had to rewire the house and all appliances with the frequency of USB connector changes!
