  1. 📄(english translation) Investigation report on the accident to the @RobinAircraft #R3000 registered HB-KEQ on 11/11/2022 at #Megève / Approach below the approach slope, collision with trees on final. bea.aero/en/investigation-repo

  2. Dmitry is back again with another minimal computer. Last time he managed to boot #Linux on an #Intel4004¹. Now he wants to run #vi, #gcc, and #make, ends up doing it on a tiny #STM #microcontroller with a luxurious 32K of flash and 8K of RAM. The 4004-based machine took a *week* to boot, this one takes just a minute!

    It's again made possible w/ #MIPS #emulation. The overclocked host CPU emulates a MIPS #R3000 at 1.65MHz with FPU disabled.

  4. Btw, the #MIPS #R3000 is the #CPU used in the original #PlayStation. So this ancient 4-bit #Intel 4004 is emulating a literal PlayStation CPU. Incredibly slowly, but it does:-)

  5. This is crazy. Someone managed to run #Linux (v4.4) on an #Intel 4004 #CPU from 1971, one of the first commercially available microprocessors ever.

    The craziest part: It became possible by writing a #MIPS #R3000 #emulator in 4004 #assembler that fits into the 4096 bytes¹ of addressable memory. The emulator then runs the kernel. My mind is blown.

    ¹) The memory was eventually expanded to 8192 bytes via some bank switching trickery as the article explains
