How to test the Macintosh System 5, 6 and 7 with Mini vMac


The Macintosh is a historical computer, like it or not Apple has to recognize how important it was. And its software was its essence. Do you want to try out that software that old Macintosh personal computers implemented? Today we show you how to test the Apple or Macintosh System 5 and 6, in addition to System 7 and 7.5, the operating system that drove the Mac to success. All thanks to Mini vMac.

Mini vMac, the tool we will use

For this guide or tutorial we will use Mini vMac . This is derived from the original vMac, which was not updated at the beginning of the century. But thanks to Mini vMac we can continue to use this great tool.
And what does Mini vMac serve us for? This tool allows us to load a ROM from a Macintosh Plus, for example, and run there the old operating systems that could be used on that computer. This means that we can use Macintosh System 5.0, 6.0, 7.0 and 7.5 as if it were a virtual machine.
And for what operating systems is Mini vMac available? Do I need macOS? No. The question should be rather "what systems does vMac not support?". And is that Mini vMac is available for countless platforms. Seriously, think of one. That is compatible :
  • MacOS (and Mac OS X)
  • Mac OS 9
  • Microsoft Windows
  • FreeBSD, OpenBSD and NetBSD
  • Linux
  • IOS (with Xcode)
  • Android
  • Windows Mobile 5.0
  • Pocket PC
  • Nintendo DS and 3DS
  • And more!
As you can see the list is long. You can use Mini vMac almost anywhere , but for simplicity in this tutorial we will only explain to use it on a desktop computer (macOS, Windows or Linux). With a simple search you can find great tutorials to install Mini vMac on the device you want. And if you have any doubts you can ask us for the comments.

What is Macintosh System?

Macintosh System, Apple System, or System Software . For those who do not know, these are the beginnings of Apple's operating system.
The first Macintosh operating system was System 1.0 . This operating system is reminiscent of the current MacOS , but with many changes . For example, items like the Finder and upper menu typical of the Mac in that version were already present.
Then came new versions of this operating system, to System 7 , which was the most popular version of this first series of operating systems of the big apple. After these came Mac OS 8 and Mac OS 9 , which we will discuss in an upcoming article. And after these came already "known history", ie Mac OS X (the current macOS ).

System 5

This is the first vintage operating system  we will discuss in this article. This one was released in 1987 .
The main novelty of System 5.0 was the MultiFinder . This meant that you could run multiple applications at once. But this multitasking was somewhat limited in this version.
In addition, another change that was there was in the nomenclature of the operatingsystem. Before this version was denoted to the operating system by version of the operative system itself and by the version of the Finder. This was changed in this version, which was simply denoted by Macintosh System Software 5.

System 6

This version of 1988 introduced few practical novelties in itself. Instead in System 6.0 added support for the new Macintosh, including the first Apple laptop, and tried to improve the overall operating system.

System 7

Unlike in the previous version, here the changes could be noticed more. In fact, this version is classified as the second major update of Macintosh System Software.
In this version the graphical interface changed, but also optimized management of RAM , so going to have 32 - bit memory addressing.
Changes were also made in the way that multitasking was implemented. In addition, the recycle bin was redesigned to a format similar to the current one, since then no longer emptied when turning off or leaving the Finder. Also say that System 7.1.2 began to support PowerPC processors  .

How to test the System 5, 6 and 7.5 thanks to Mini vMac

Let's go to the nougat! This is what we were expecting. Let's see how we can use these operating systems from Mini vMac:

1. Install Mini vMac

The first step of all will be to download the Mini vMac application for the operating system you are using. We will do this from the official website of Mini vMac , where we will find the necessary links. In case of using macOS / OS X we will download the one that says "Macintosh OS X". In case of using any other operating system we will download the corresponding version and follow the installation steps.
If we use macOS we will download only the application ready to use. We will not have to do anything else. It will suffice to open it.

2. Download a ROM

The second step will be to download a ROM so that Mini vMac can be executed simulating being the Macintosh of that image.
With a little search you can find a ROM of a Macintosh Plus. Although, if you want you can extract it from an original Macintosh with the steps that explain there. That would be optimal, but not all of us have a Macintosh at home.
For ease, I uploaded a compressed file with everything needed . You can take the ROM there if you are not able to get one. This file should be called "vMac.ROM" , and it should be in the same folder as the downloaded application.

3. Download the Macintosh System Software image

The third one will download the image of the operating system that we want to use.
These images can be found on the official Apple website , although for some reason some of the links to some specific versions are dropped or have changed. In the Mini vMac website you can find the two images of System 6 . Later we will have to decompress these two images using Stuffit, an application of that time that luckily still exists.
To facilitate the work for those who wish, in the aforementioned compressed file I have added several images. Among them are System 5, System 6 and a special version of System 7.5 for use with vMac.

4. To play!

We have everything! Now all you need to do is join it. Once we have the application and the ROM in the same folder and with the name indicated, we will open the app. When doing this we will see a diskette with an interrogation. At that moment we must drag our image to the window of Mini vMac.
And ready! It will begin to load the operating system that we have decided to use.

Note: If you want to force virtual machine shutdown, press Ctr + Q and then Y (without releasing Ctr).

Conclusion

As we can see, this is a rather curious application. Those who have not had a Macintosh will help us learn how System Software worked and how it evolved. For those who owned a Macintosh it will serve them to remember old time.
