Going Minimal: 64×4, The Fun in Functional Computing Heidi Ulrich | usagoldmines.com

If you’ve ever wondered what makes a computer tick, the Minimal 64×4 by [Slu4] is bound to grab your attention. It’s not a modern powerhouse, but a thoughtfully crafted throwback to the essence of computing. With just 61 logic ICs, VGA output, PS/2 input, and SSD storage, this DIY wonder packs four times the processing power of a Commodore 64.

What sets [Slu4]’s efforts apart is his refusal to follow the beaten track of CPU development. He imposes strict complexity limits on his designs, sticking to an ultra-minimalist Von Neumann architecture. His journey began with the ‘Minimal Ur-CPU’, a logic-chip-based computer that could crunch numbers but little else. Next came the ‘Minimal 64’, featuring VGA graphics and Space Invaders-level performance. The latest ‘Minimal 64×4’ takes it further, adding incredible speed while keeping the design so simple it’s almost ridiculous. It’s computing stripped to its rawest form—no fancy sound, no dazzling graphics, just raw resourcefulness.
