The second operating system in the world, after Windows, is the Macintosh. The market share of Macintosh as of January 2021 is about 17%. Film An interesting fact. The name of the system is derived from the Mekintosh apple variety. And this is not surprising, because the backbone of the team that made this computer was made up of Apple employees.
From this article we will learn how to make a mini-version of the very first Macintosh computer.
In this project, the wizard implements two versions. < br>The first version has a fake disk and the micro SD card is inserted from the side.
In the second version the SD card is installed in the front, where the original computer has a floppy drive.
-Power supply 5V 2.5 A;
-Mini HDMI to HDMI adapter;
-LCD display 640×480;
-Short ribbon cable with 40 GPIO pins;
-Keyboard and mouse (for configuration); – Micro USB hub; -Monitor (for configuration); – Micro SD card 32 GB; -Bluetooth speaker (optional);
-Adapter micro sd-card; -Seed paper; -Screws M3 X 12 mm with an internal hexagon; -Hexagon nuts M3; -Beige PLA thread;
-Blue masking tape;
Step one: two versions
In this project, the wizard implements two versions.
Version one has a fake disk in the front and a micro SD card is inserted from the side.
In the second version, the SD card is installed in the front, in the place where the disk drive is located on the original computer.
The difference in cost between the two versions is negligible. A few dollars to expand the SD card. The real difference between them is in design (lack of space inside the case).
V1 housing consists of 4 parts. All parts are printed with a layer height of 0.20 PLA filament.
MiniMacBack.stl is printed with Build Plate support only.
MiniMacFont.stl is printed vertically with supports Everywhere and Brim ..
MiniMacDisk.stl and MiniMacToggle.stl are printed without support.
MiniMacFront.stl has additional support along the back of the model. After printing, this support is trimmed and the surface is filed flush.
V2 body consists of 5 parts. Except for printing different files, the instructions are almost the same as in the first version.
After all the feet have been removed, the front and back must be sanded with 150 grit sandpaper.
The print files for both versions can be downloaded below.
Step three : nuts
After printing, you need to install the nuts in the designated places. To fix it, the master heats up the soldering iron and solders the nuts. In the first version, a lever is installed inside the body (see the last photo).
Step four: imitation disk (version 1)
In the first version, an imitation floppy disk is installed in front … The basis for it is 3D printed. You need to glue blue masking tape to this part. Then the part is installed in the groove in the body.
Step five: sd card adapter (version 2)
If the adapter is in the case, then you need to disassemble it and get the ribbon cable together with the board.
Next, insert the extension ribbon cable through the slot in MiniMacDiskFront_V2.stl, taking care not to damage the cables on the underside of the board. The board should be under the small tab.
Next, you need to stick MiniMacDiskBack_V2.stl onto the disk support.
Step six : Verifying Russberi Installation
There is very little space inside the back of the case (MiniMacDiskBack_V2.stl) and there are 2 more ribbon cables connected to the Raspberry Pi Zero. You need to make sure that Rusberi is installed in the slot without any problems. If necessary, you need to adjust the details.
Step seven : Raspberry Pi Zero setup
Raspberry Pi Zero W needs to be prepared. If the 40-pin GPIO header was not pre-installed, you will need to solder it. Next, install the heatsink.
According to the instructions from the official Raspberry Pi website, you need to install the Pi OS and image processing software on an SD card. You need an OS with a graphical interface.
After installing the OS, you need to connect the power and monitor to Rassberi.
When you start it for the first time, the default setting is language, time zone, etc. Then you need to connect to the wireless network, and wait for the system update.
Now you need to make some changes to the default settings. Go to the top left corner and click on the Raspberry icon. Select “Settings” & gt; “Configuring the Raspberry Pi”. In the dialog box, if it is not selected, select the “System” tab. Make sure the hostname is raspberrypi. This is the name you will use to access your Pi wirelessly.
Then select the “Interfaces” tab & gt; Enable SSH. Click OK.
Just in case, you need to write down the IP address. Hover over the Wi-Fi icon in the upper right corner of the menu bar. A window will pop up with the following entry: wlan0: Configured, followed by a number in the format XXX.XXX.X.XX/YY. We write XXX.XXX.X.XX. In this case, it is 192.168.1.26.
After the update is complete, select “Restart”.
Step eight : software
To emulate a Mac on Rusbury, you need to perform some actions. There are special emulators and you can “build” it directly on Rusbury, but the system will be very slow.
The wizard decided to build the emulator on his computer.
The wizard uses the CyberDuck program. It is available for both Mac and Windows.
Links to guides on how to do this can be found at the end of the article.
Step nine: assembly
After installing the software, the wizard starts assembling the device.
Remove the protective cover from the display and replace it. The top and bottom right corners should fit snugly into the tabs.
Then you need to carefully install the ribbon cable at the top of the display. Connect the other end of the cable to the Pi.
For version 1.
Installs the Pi into the back of the case. The connectors enter the holes on the back of the case. Sets the toggle switch and assembles the two body halves together. Connects power.
For version 2.
Neatly folds the ribbon cable as shown in the photo. The cable should come out of the connector at the back and the red edge should be at the top.
Attaches the ribbon cable to the Pi. Installs the SD card slot.
Connects the ribbon cable to the back of the display. Sets Rusberi back in place. Assembles two halves of the case.
Step ten: sound
The Rusbury board has a built-in Bluetooth module. The master uses a Bluetooth speaker to transmit sound. All you need to do is enable it and sync with Rusbury.
