Enthusiast modder creates the smallest-ever PlayStation using genuine chips for console's 31st anniversary — redesigned PCB is less than a quarter size of the already dinky PS One revision

The original PlayStation wasn’t built to be particularly compact, but later revisions like the PS One managed to get pretty small, while retaining CD media compatibility. However, console hacker Thedrew has managed to condense that already dinky PS One revision motherboard down to less than a quarter of its prior size. This custom PlayStation motherboard is the smallest ever made, according to Hackster, and perfectly timed to celebrate today's 31st anniversary of the console's release.

Thedrew’s creation is an “Original hardware for the win” design. Sure, it could have gone much smaller if the project had been propped up by an FPGA, a modern SoC with an emulator, or some similar electronic/software concoction. This is the real deal, though, with original PS One rev PM-41 chip packages onboard. In other words, it uses Sony’s original CPU, GPU, SPU, RAM, and BIOS chips.

With these components in hand, Thedrew designed the most compact supporting motherboard his skills and resources would allow. The current working model is a quarter size of the PS One mobo, says the console hacker in the above video. Actually, Rev.1 of the compacted mobo measured just 73 x 59mm. That gives us the following rough comparison:

• Original PlayStation motherboard – about 10 x 7-inches
• PS One motherboard – about 7.5 x 5.5-inches
• Thedrew’s PS One redesign – less than 3 x 2.5-inches

Now that the custom PlayStation motherboard is ready and working, we eagerly await the next steps from Thedrew. Towards the end of the video, he says, “now we have a working prototype, let’s make it even better.” This work should find its way into a range of projects under the umbrella term of “The PS One Redesign Series.”

The original PlayStation's anniversary

31 years ago today, Sony released its first blockbuster games console to the unsuspecting public. Commonly abbreviated as the PS, PSX, or PS1, this affordable box of wonders sparked the immersive 3D gaming home console revolution. The PS One (year 2000) was a significantly smaller footprint console that played the same first-gen games.

In 1994. Sony's $299 TV-connected gaming system clearly outshone most contemporary PCs in 3D prowess. Remember, it wasn’t until late 1996 that the legendary 3dfx Voodoo appeared on the scene to bring new levels of 3D realism to PC gaming. Coincidentally, the Voodoo would also cost $299 at launch. You'll have to pay a lot more to buy the best PC gaming graphics card in 2025.
