Turn an iMac G4 into an external monitor with the DockLite G4 modification.
It's not the best exhibit, but it's definitely my favorite.
It has been two decades since Apple stopped producing the iMac G4, a computer that stood out for its peculiar design, featuring a semi-spherical base and a flat LCD screen mounted on a sleek adjustable stand. While in its original state it serves as an attractive object of nostalgia, it is now considered obsolete. I always wanted to have one, but I never had the chance. However, thanks to Juicy Crumb's DockLite G4, I can now use this classic iMac daily as an external monitor.
The DockLite G4 is a motherboard that easily replaces the original one from the iMac G4. This accessory includes an HDMI port, three USB-A ports, a USB-C port, and 3.5mm audio connectors. The highlight is that it utilizes the existing mounting holes and internal connectors for power and video, meaning you only need a few screwdrivers and a prying tool, without the need for soldering.
The installation process took about 30 minutes. I bought a 17-inch iMac G4 through eBay, removed the original motherboard, installed the DockLite, and closed it back up. Suddenly, I could connect various devices, from a MacBook Air to a replica of the GBA SP by Anbernic. Juicy Crumb even provides a very helpful instructional video. This installation was much simpler compared to other DIY methods.
With the DockLite installed, my iMac functions as an external monitor. It turns off when my computer does, although it is necessary to press the power button on the iMac to turn off the backlighting, and I can control the brightness both through software and with buttons on the back.
The reason behind this modification is simple: this computer looks incredible on my desk. However, there are some things that are lost in the process, such as access to the iMac’s optical drive. Additionally, it cannot be used as a standalone computer unless more internal components are replaced with those of a Mac Mini. A positive aspect is that the installation is reversible, allowing the original motherboard to be reinstalled if necessary.
The DockLite G4 costs $260, a price that reflects the "time, effort, and money to bring to market even a relatively simple product like the DockLite," according to Timothy de Denaro, CEO and co-founder of Juicy Crumb. He also clarifies that the DockLite G4 "is a low-volume product" and that "each unit is manually tested by me before being shipped" to customers. While the explanation seems reasonable, it does not change the fact that I have invested a lot of money and effort to use a low-resolution screen with limited viewing angles. However, I did not acquire the DockLite G4 for the quality of the 21-year-old LCD screen of the iMac G4. I did it because this computer looks spectacular on my desk, and I wanted to use it daily.
