8 Classic Operating Systems You Can Access in Your Browser

Dan Price Updated 11-04-2019

We all love the cutting-edge operating systems of today. But there are times when it’s fun to cast your mind back to yesteryear and relive some of the operating systems of old.


And no, we’re not talking about those of you who still insist on running Windows 7, or worse, XP.

If you want to emulate Windows 95, Mac OS X Lion, and more, you’ve come to the right place. Here are eight classic operating systems you can access in your browser.

1. Windows 95

Released in August 1995, Windows 95 was one of the defining operating systems of the decade.

It laid the foundation for the Windows we all recognize today. The Start menu and the Taskbar made their respective debuts, and for the first time, a Windows operating system didn’t rely on MS-DOS for file and disk access.


This Windows 95 emulator runs Windows 95 OSR2. The version did not have USB support and struggled with Pentium.

While running the emulator, you can use the controls in the upper-right hand corner to toggle full-screen mode and to enable/disable the mouse. As with all browser-based operating system emulations, any changes you make will not be saved between sessions.

2. Classic Macintosh

Back in 1984, Apple released its first machine in the Macintosh—later “Mac”—line of products. It was a ground-breaking computer, becoming the first mass-marketed PC to offer a graphical user interface.


This Macintosh emulator runs System 7.0.1 with three early Mac apps—MacPaint, MacDraw, and Kid Pix.

Because the operating system requires significantly fewer system resources than the Windows 95 emulator, it will load in your browser considerably more quickly.

3. Macintosh Plus

Two years after the introduction of the first Macintosh computer, Apple released the follow up: Macintosh Plus.


It had an original price tag of $2,600, proving that Apple’s penchant for exorbitant prices is far from a modern phenomenon. The computer shipped with 1MB of RAM (and support for up to 4MB), it supported up to seven peripherals, and it had an 800KB floppy disk drive.

By 1986, significantly more apps and games were available. This emulation includes Risk, Cannon Fodder, and Shufflepuck.

4. Windows 3.1

Windows 3.1 hit the shelves in April 1992, replacing the original Windows 3.0.


Despite the similar name, it offered vast improvements over its predecessor. Most notably, the introduction of a TrueType font system turned the operating system into a desktop publishing powerhouse for the first time. Three fonts were natively available—Arial, Courier New, and Times New Roman.

Other features seen for the first time included drag-and-drop icons, mouse support in MS-DOS applications, and the Program Manager app. The theoretical maximum memory limit was an era-busting 4GB, though in practical terms it was 256MB.

Windows 3.1 was replaced by Windows 95, but support lived on until as late as 2008.

The Windows 3.1 emulator offers classic games such as Minesweeper and Solitaire, accessories like Write, Paintbrush, and even access to the Control Panel.

5. AmigaOS 1.2

AmigaOS version 1.2 was first seen on the Commodore Amiga 500.

The 500 was the best-selling computer in the entire Amiga range. Announced at CES 1987, it was released around the world in the spring.

Although it was a multi-purpose home computer, the PC carved out a niche for itself as a gaming machine. Titles such as The Secret of Monkey Island, Lemmings, Elite, and Sensible Soccer won worldwide acclaim.

Specs-wise, the Amiga 500 had a resolution between 320×200 and 640×400, a 32-color screen, and 512 KB of RAM.

This Amiga 500 emulator includes old Amiga apps such as Boing, Robocity, Juggler, Dots, Boxes, Lines, and Speech.

6. PC DOS 5

At the same time that Apple and Commodore were jostling for market position with their respective Mac and Amiga lines, IBM had swiftly become the manufacturer to beat with its IBM PC range.

The first IBM PCs went on sale in 1981, but this emulation of the PC DOS 5 is running on the 1986 update—the IBM PC XT 286.

The XT 286 had 640KB of RAM, a 20MB hard drive, and 6MHz processors.

PC DOS 5 itself was released in 1991 and marked one of the most substantial DOS overhauls in its history. Perhaps more notably, however, it was the last version of DOS for which Microsoft and IBM shared the full code.

The PC DOS 5 emulation offers three classic games for you to check out: Wolfenstein 3D, the original Civilization, and Monkey Island.

7. Mac OS X 10.7

mac lion demo

Mac OS X 10.7—also known as Mac OS X Lion—is the most recent operating system on our list. It only went live in July 2011.

Like the other operating systems we’ve looked at, Mac OS X 10.7 saw a lot of “firsts” for Apple users. For example, it was the first time we saw AirDrop and the Launcher app, and it was the first Mac operating system to ship with the emoji font and FaceTime.

Lion also saw the end-of-the-line for some features. Front Row, iSync, and the QuickTime Streaming Server were all dropped.

Unfortunately, modern restrictions mean the Mac OS Lion emulation is more restricted than the other systems. It’s a CSS recreation, so you can only access the desktop, menus, and some basic system information. However, you’ll still be able to get a feel for what the operating system was like.

8. Windows 1.01

windows 1.01 demo

Released in November 1985, Windows 1.01 was the first publicly-available version of Bill Gates’ operating system.

The operating system is essentially a graphical front-end for MS-DOS. Indeed, Windows 1.01 ran as an MS-DOS program.

Apps on the OS included Calculator, Calendar, Clipboard Viewer, Clock, Notepad, Paint, Reversi, Cardfile, Terminal, and Write. They are all available in this emulation.

Behind the scenes, Windows 1.0 also had its own drivers for video cards, mice, keyboards, printers, and serial communications, and applications.

    Back in '85 IIRR, my buddy got an Apple IIe. I was a stoner then and didn't care for anything about it until he showed us a game to play on it...'Hitch Hikers Guide to the Galaxy'!

    Man! The hours and hours we spent trying to get to the next 'step' or whatever it's called! Stoned out of our heads, lol. It was a blast!

    I never knew that Windows 1.01 (MS-DOS Executive) included the 'Write' word-processor. Interesting... Never a big fan of Win3.x, in those earlier days but always had a soft spot for 'Write' - it works fairly well in the emulator too!

    I'm sure I would have dismissed it early on (in the mid to late 80s) as being too big and bloated (nearly 200kb in the emulator version) but looking at it now: the thing is absolutely svelte.

    Then try this. On chat tonight one participant reported he still does his US federal income tax, and state tax, on an Adam - 8 bits, 64K memory. Why not? Back in the day it was the backroom machine for the H&R Block tax preparation agency. Moore's Law even applies in classic computers; now folks have got them driving current printers, running SSD hard discs based on CF cards, and other neat tricks.

    The software did the job then and can still be set up to do the job now. But it's simple enough for a knowledgeable user to tamper with and adjust to suit, like being simpler and easier to work with.

    Just because Ford brings out a new model of your car doesn't mean the old one stops working. You might not even agree the new one works as well as the old (XP forever!)

    The Amiga is a good, powerful, very user-friendly computer, with a spreadsheet program my wife found highly adaptable to just exactly what she wanted to do the way she wanted to do it. So she set it up to do just that and has every incentive not to change.

    In fact, she needs two other spreadsheets for two other purposes, so she uses a quirky independent one from a long-discontinued suite called Easy Office, in the XP Virtual Machine on her Win7 Dell, and Kingsoft's free Office competitor for the other. Because they work.

    Why should it be a big deal to look for the tool that does the job you need the way you need it done - and refuse to waste time and money messing around with something not as good because it's new? That's nuts. Sane people choose the answers that work best.

    My wife has the commercial (Colanto) Amiga emulator running in the XP virtual machine in her Win7Pro laptop. It lets her play with her favourite Amiga graphics programs without firing up her Amiga 3000, which she uses for the spreadsheet on which she keeps the household accounts.

    She also has the emulator for the Adam, the 8-bit computer built up from the popular Colecovision video game. In fact we plan to attend the 27th annual Coleco Adam users' convention in Cleveland (Adamcon 27) in mid-July. Information can be found at which is specific to the Adam community, though the gamers (who are still writing and issuing very collectible new games) also often hang out at

    There is also a large Commodore community that has emulators for the PET, C64, and C128 as well as various Amigas. Start your search at

    As a "not real tech saavy" computer user, I absolutely hate Windows 8. I have fought this new computer from day 1. It is at the Geek shop to have Windows 7 put in. They can do whatever they want with Windows 8. (I know what I'd like to do to it.) I do not have a touch screen monitor, what was Microsoft thinking? If I had known Microsoft 8 was such a headache, I would never have bought this new computer.

      Do you mean Windows 8 vanilla or 8.1 because a lot of changed were made on 8.1 but by then it was pretty much too late. The ship was damaged beyond repair but 8.1 added a lot of features in the box to make Windows 8 smooth and is more compatible with things then 10 which still has the god awful phone apps stuff.

      Win 8.1 has an arrow that allows you to access all your programs at once so you can organize things (yeah) WITHOUT 3rd party software involved or any sort of tinkering but MS failed to advertise that and they only ahve themselves to blame.

      Windows 8.1 is what Vista and 7 should've been. I HATE windows 7 but I only have it because Windows XP is not secure anymore and I refuse to have 10 which does nothing but make computer noise.

      I honestly don't know why MS couldn't let you edit things in the regular Windows 8. Windows 8.1 is a *fix* but for obvious reasons they are not allowed to say as such.

      There are many "commanders" available for current Windows computers. Closest in look and feel to the Norton original is Midnight Commander. It was created for console-mode Linux, but has been ported to Windows. I use it in Linux all the time.

      For Windows, my current favorites are 7-zip and Double Commander.

      I especially liked Forth - on TRS-80 Model III (also I had two TRS-80 Model I - first with cassette tape program Save and Load for which I bought a case of very short tapes (5 minutes?). Forth was a disk operating system and application like word processing where one could look at the code and learn how. Reminds me of 2005 vintage One Laptop Per Child (from MIT) and its coding in Python. Also, have Altair 1975 with Kansas City BASIC.

      If you are interested in experiencing what I consider one of the more prominent efforts by Apple, search for and install the Macintosh System 7.5 (I believe emulators exist for it, though I cannot recall if they are available for Windows).

      System 7.5 was a leap in OS design unparalleled by Apple itself to this day.

    • D
      March 14, 2014 at 5:17 pm

      The inspiration for Apple in designing System 7.5, of course, was one of the last iterations of the Amiga OS (even if they never admit to such). An emulator IS available for that OS (and runs on Windows).

      Er I was there at the start and yes Windows 1 was basic but the precurser was called GEM and about all it had was a Rotodex type card file. However the most significant thing that came out of Windows was the standardisation of programe interface with the user. Before it was necessary to learn the individual command keys of each package used. Each being totaly individual. So Wordstar, Supercalc and DBase each had their own quirky command structure.
