Pimoroni HDMI 8″ IPS LCD Screen Kit – 1024×768
8Bitdo Sn30 Pro USB Wired Gamepad (2)
USB Keyboard + USB Mouse
Raspberry Pi case (used a passive cooling aluminum case)
Micr0 HDMI cable
5V 3A USB-C power supply with on/off switch. Switch mounted in the handle area for easy access.
A couple of build notes. I chose to go wired for all the peripherals so that the computer is always available. The keyboard and mouse use the low speed ports. The powered USB hub is in a high-speed port, which makes it great for being able to back up the system via a USB SD card reader, add devices that might need more power, etc.
To keep things quiet, I went for a passive cooling case for the Pi. Given how much airflow there is in the case, it seemed like a good solution and avoided having anything noisy running in the dining room all the time.

For the System 7.5 emulator, I’m running the Arm compiled version of Mini vMac. Separately, you’ll need to find a source for both your ROM and boot disk. I found this tutorial from the Macintosh Librarian to be super helpful (view on YouTube) for figuring out the software side of things. As you can see from the photo, the total memory is a bit larger than the original Macintosh (64x with a 1.1GB boot disk).
