Good on ya mate. I never got to writing my own OS from scratch but I did build my own 8088 Microprocessor complete with a 4Kbyte BIOS. This was based on an excellent book by Robert Grossblatt

Things have moved on since the 80's single mode processor model and some smart kid called Linus Torvalds kicked the build your own OS revolution off in 1991 aka LINUX. (based on POSIX)
