Welcome Home Linux, I built a couple 6809 64 kilobyte home computers kits in 1982 and wrote assembly language routines to access a 8" floppy disk drive. Worked for NEC Electronics 1997-2001 with MIPS Vr4100 series SOC microcomputers running Microsoft Windows CE. Support Brad LaRonde with his Linux MIPS software on the Vr4181 Osprey handheld development reference board. Paris February 2000 Linux show debuted the V4181 as the first handheld Linux computer in the world. This Vr4181 MIPS cpu became the Agenda VR3 Linux Handheld computer in 2000.

Now in 2021-23 I am able to play with home computers by testing, building ARM64 FreeBSD 14.0-CURRENT software and packages on a Raspberry Pi 4B with 8 gigabytes dram memory. Life is sweet again playing with a home computer that plays YouTube , Frankspeech.com, AmericasVoice.news videos and hdmi audio on a HDMI TV monitor screen.

My Blogpost has many examples of using FreeBSD software on the Raspberry Pi 4B hardware, includes a 500GB SSD, HDMI monitor screen with audio speakers
