An Arm Mainboard for the Framework Laptop

Using the repair-friendly Framework 13 laptop chassis, I've tested the low-end x86 option (a Ryzen AI 5 340 Mainboard), the fastest RISC-V option (DC-ROMA II), and today I'm publishing results from the only Arm Mainboard, the MetaComputing AI PC, which has a 12-core Arm SoC and up to 32 GB of soldered-on RAM. My Framework 13 has run on x86, RISC-V, and now Arm, making it something of a 'Ship of Theseus'.
