12 examples of old tech that never dies


The tech entire world normally appears to be like an unlimited parade of incredibly new suggestions, architectures, languages, and devices. It also occasionally comes about that a after-new matter sticks all around a little bit as well extended. Maybe a gadget just would not wear out. Possibly the disruptive alternative under no circumstances displays up. Once in a while, the fantastic alternative turns out to be not very as excellent as the previous standby.

Let us rejoice these artifacts of the computer market that steadfastly deliver—day in and working day out, 12 months after calendar year, some of them for decades. Sure, they may well not have flashy conferences named soon after them, or make their large debut in an overhyped IPO, but they do what they’re intended to do.

Here’s a glimpse at some of the very best aged tech that never ever dies. Concepts and things—chips, plans, languages—that somehow missed the cue to leave the stage. Oh, we may well not see them a lot anymore. Occasionally we even fail to remember they are there. But this outdated tech retains jogging on, smooth and unremarkable. Consider it a tribute to the suitable of sound engineering, and quite possibly a reminder that excellent technology doesn’t automatically will need to be changed each and every couple a long time.

The Z80 chip

The Z80 processor chip started in 1974 as an offshoot of the wildly productive Intel 8080. It was a competing chip that presented additional registers and much more instructions but was mainly binary appropriate with the 8080. Builders could run their aged 8080 code or tweak it with the additional functions to be a little bit more rapidly.

Though Intel moved on to develop greater, superior, and insanely more quickly x86 chips, Zilog’s Z80 continued to thrive in a lot less noticeable niches like microcontrollers. These days, makers who want to add a steady microprocessor with a deep, wealthy selection of libraries can pick out in between a amount of choices both of those from Zilog and from 2nd and third sources. And for those who want to establish on the custom, some companies like Toshiba have slowly and gradually expanded the line by adding broader buses and fatter registers.

Recreation emulators

Any person who wants to participate in outdated video clip games can flip to a selection of open up resource emulators that enable us run the original code on modern day equipment. There are strong implementations of popular platforms like Super Nintendo but you can also obtain far more obscure frameworks like the Commodore Amiga. Some developers have even observed a way to run the code in the ROMs in well-known arcade game titles. Sure, the more recent game titles render their very first-person heroes in a way that lets you truly feel every sweaty pore, but there’s some thing timelessly fulfilling about successful a match rendered in ASCII on a terminal display screen.


A shocking large variety of software package plans that were penned for the primary Windows continue on to sail on. A person these kinds of system is PuTTY, employed to established up an SSH connection. I routinely use PuTTY to log in to cloud devices. It can even however initiate the initial SUPDUP login protocol that dates from the ’70s and ’80s. A tiny group of volunteers maintains the initial code, which was originally launched in 1999. The most basic way to use PuTTY is to down load an exe.


Perhaps it can be not just good to get in touch with FreeDOS outdated tech. Why, just this 12 months another person included a new variation of Edlin, the basic line-primarily based file-enhancing method. And that’s not all: a selection of new and revised versions of old command-line code are now part of FreeDOS. But the ongoing progress does not modify the truth that the job is devoted to hold-alive DOS, the command line, and courses that operate on it. If you have got some outdated DOS software program that you want to keep applying, FreeDOS is a single of the most straightforward approaches to do it. Take a journey back in time and delight in the fast, responsive earth of DOS. Here, you can be sure your cursor will by no means flip into a spinning, unresponsive ball. A cursor will be a cursor, as it must be.

BSD Unix

Immediately after Bell Labs built Unix, a range of clones started appearing. When AT&T tried to exert management around the mental residence, a clever band of programmers wrote their very own variations of the widespread command-line utilities and unveiled them under the now ubiquitous Berkeley Software Distribution (BSD) license.

Currently, this code is typically identified during the Linux environment in distributions by Purple Hat or Ubuntu. A strong main even now lives underneath the name of BSD, and retains to many of the conventions that have been very first founded at Berkeley. Variations like OpenBSD, FreeBSD, and NetBSD however run rapidly, clean, and light-weight.

IBM Laptop keyboards

IBM’s initial private laptop or computer came with a Product M keyboard that stays one of the most beloved options for communicating with a laptop. When IBM stopped earning that model of keyboard in 1996, a handful of correct believers took the tooling and set up Unicomp, specializing in traditional Computer keyboards. Now, you can get brand name new variations of the keyboards you love, but with additional present day electronics that speak to more recent PCs. Newer mechanical keyboards have their rewards, and they appear in versions with distinctive levels of clickiness, but there’s nevertheless absolutely nothing as stable and successful as the first Product M.


This program 1st arrived in 1984, and it is assisted scientists and engineers multiply matrices at any time given that. MATLAB has enhanced drastically about the years, and now supports item-oriented programming and graphical interfaces. But at its core, MATLAB is nonetheless a programming platform for creating and examining big matrices.

Magnetic tape

You may well think that spinning tape drives went out of fashion following the 1960s, just like the skinny ties and miniskirts worn by office environment staff in that working day. When shifting magnetic tape doesn’t command the identical share of the marketplace that it at the time did, some people continue to appreciate the technology. It really is uncomplicated to ship or retail store, and it truly is a great deal a lot more steady than Flash chips. It is also not pretty exact to say that the latest drives are the similar aged technological know-how: After all, tape businesses have included numerous of the exact same innovations that challenging disk companies use to make their stunning densities. 1 new format, the LTO-8 produced in 2017, is explained to shop 12 terabytes on a tape. A different from IBM, the 3592 Jaguar, can maintain 10 terabytes. That’s not poor when compared to the old floppy disks.


Very long before Twitter and SMS, physicians, stockbrokers, and absolutely everyone else who wanted to be reachable relied on a radio paging process able of broadcasting just a couple digits. Newer selections like WhatsApp run over mobile mobile phone networks or the frequent internet. They could offer multimedia gloss and the potential to include a picture or an emoji, but they really don’t provide the exact trustworthiness.

That’s why medical professionals, nurses, and EMTs keep on to use pagers for essential communication. Just one of the nation’s biggest paging systems claims it is nonetheless processing 100 million messages each and every thirty day period. Pager companies haven’t sat continue to, possibly. More recent variations give encryption and HIPAA protections, and some even allow two-way communication. But at the main is the same simple, responsible gadget that debuted in the 1970s.

SQL databases

Oracle introduced the to start with commercial SQL database in 1979. Microsoft released its SQL databases in the 1980s. PostgreSQL and MySQL adopted in the 1990s. Other database designs have arrive alongside considering the fact that, but most programmers still publish SQL queries. Which is why the organization plan for companies like Google, Amazon, Neon, and PlanetScale—to name just a few—amounts to repackaging a basic SQL databases as a services.

To be fair, some cloud database platforms offer intensive modifications, like separating the logic from the storage layer to velocity up certain types of queries and guidance massively scalable storage. But from a programmer’s standpoint, an SQL database in the cloud seems to be no unique from the very same previous interface they’ve been working with for decades. Builders may possibly not really like SQL, but we know it and have an understanding of it, and we hold coming again to it.

ARM processors

The ARM architecture was one of the fundamental chips that emerged through the RISC revolution of the 1980s. Now, pretty much 40 many years later on, ARM cores are located pretty a lot in all places. They’re in embedded machines like the Raspberry Pi units that began showing up in 2012. They are also in the best-of-the-line Apple MacBook Professionals, albeit in a really various type. No matter what condition it takes, ARM’s straightforward architecture has proved to be remarkably agile. It is applied to develop some of the most productive chips with the greatest ratio of computing electric power manufactured to electric electrical power eaten.

IBM mainframes

There may perhaps be no increased instance of an old standby than the flagship laptop from the corporation that developed and led the computer system market by means of the ’50s, ’60s, and ’70s. IBM designed its first mainframe in 1952, about 70 many years ago. It is solely possible that some of that identical code—originally made making use of punch cards—still runs nowadays in some form or form. If you’ve got ever wondered why COBOL builders are continue to in demand from customers, blame the IBM mainframe. Many businesses are continue to managing the similar trusted stack of logic that does not don out.

The mainframe’s operating technique and languages have been enhanced and augmented in excess of the yrs, but a lot of the code principles have not adjusted. There is a cause why IBM consumers like the top rated banking companies go on to have on. Possibly they’re laughing quietly to them selves as fiscal tech corporations occur and go, bragging as they do about their present day program and languages.

There definitely is some thing about old tech that by no means dies.
