My first computer was a 486sx 25Mhz [1] The rig (tower, monitor, etc.) cost around $3,000. We got the SX instead of the DX because it was $500 cheaper. And I wanted a 16bit sound card. (Note that this is in 1992 dollars. Today it would cost over $7,000) My parents didn't have a lot of money, but my great-grand father passed and they used some of the inheritance to buy the computer. I was instantly hooked. In hindsigh…

> In hindsight I see how much of a gift my family gave me.

Gotta tack on to this thread showing appreciation for parents. We could never afford new computers in the 90s, but luckily my dad could bring home obsolete equipment from work. We were thus always at least a generation behind. I remember my friend's Pentium feeling like sci-fi compared to our 386, but my goodness it completely molded my life!

Later, towards the end of the 90s, those sci-fi Pentiums were obsolete, so I got a few to run "that weird Linux stuff" on. Since it was considered junk, nobody cared what I did with it. To this day, if I happen to hear Metallica play and there's early winter's first smell of snow in the air, my mind will be transported back to that school night I secretly stayed up wayyy too late and discovered SSH for the first time. Haven't looked back.

Thank you, dad! I just hope general computing devices owned by regular people are still natural by the time my children come of age.

Earlier quoted context omitted.

It was really the 386 that was the beginning of modern computing, since it had a mmu.

Except the 486 had hardware floating point, essential for technical work.

You could buy a 8087 for your 8086 or 8088, the 486DX just moved it on chip.

You really needed a Pentium or equivalent to do all three at once without noticeable lag as you typed.

WordStar originally didn’t have a spell checker. It was an add in product. And even after SpellStar was integrated (a response to the NewStar clone’s built-in spell checker), it was never as-you-type spell checking, which is what we got in Word 97, and what consumed the cycles on a 486.

Word 97 also had as-you-type grammar checking, which wordstar never had. Wordstar did have an add in extra cost grammar checker whose name escapes me at the moment. But again, it was never real time.

Yes, programs have become bloated, but it is worth it to compare apples to apples.

One might argue that real time isn’t necessary, and one might be right. But that’s different from poorly written.

Several operating systems on 286 (eg Xenix, Coherent, OS/2) used its MMU for multitasking and memory protection. See https://en.wikipedia.org/wiki/Intel_80286#Protected_mode

The 286 protected mode did not allow for a 32-bit flat address space and was heavily half-baked in other ways, e.g. no inbuilt way to return the CPU to real mode without a slow and fiddly CPU-reset.

• Ran my first Linux at home on a i486-DX2 (33 MHz, 4 MB RAM), which supported a decent X11/R6 performance in color in 1992, with a 14" CRT. • Ran my first real UNIX at home on a PA-RISC (HP 9000-715/75 with HP-UX 9.03 and 96 MB RAM) in 1997, 20" color CRT. • Today, Linux is still here, but on a 2-CPU, 140-core AMD server with 2 TB RAM, hundreds of TB NAS and a 40" TFT... (and it still takes too long to open the bloa…

Wouldn't the DX2 be 66 MHz? Or did you intentionally run it at 33 MHz?

Apples to apples? More like Windows to Windows. LOL

Pentium is a bad processor? It's way faster than 486, especially on FP it's not even close.

The Pentium was great, but the 60 and 66MHz versions were not liked, they ran way too hot.

I think from the price people also expect a similar performance boost as going from 386 to 486. What made Pentium also confusing is that during this time Intel introduced PCI.

From a 486 with VLB to a Pentium with PCI everything became a lot nicer.

Linux kernel version 7.1 will drop support for 486: "Linux devs think even one second spent on 486 support is a second too many." https://arstechnica.com/gadgets/2026/04/linux-kernel-maintai...

I can understand running an old 486 machine for nostalgia reasons, or because you have some old industrial equipment that relies on it and even one second spent replacing it is a second too many, but I struggle to imagine why you'd want or need to run a modern Linux kernel on it.

Coherent was the first Unix-like OS I ran, on a 386SX box. I think it was Coherent 4.x.
