In 2018-2020, several Kickstarters promised "The Ultimate 64-bit SBC" featuring quad-core Rockchip or Allwinner chips. "MK3" was the third revision of a PCB that never shipped. Users who paid for the "463" tier (Batch #463) received nothing. Hence, "Not Found" (literally missing shipment) and "Better" (they moved to a Raspberry Pi 5).
To understand why users are constantly looking for something "better," you have to look at the three standalone titans of the scene that enthusiasts attempt to bridge together: 463 mk3 ultimateu64 not found better
: UMK3 is often a "clone" or "update" of the original Mortal Kombat 3 463 mk3 ultimateu64 not found better
