This brings back memories... I remember fresh out of high school following a few tutorials and writing a basic kernel & code for my old Pentium MMX and reading through the intel developer manuals for the 386 processor , and all the complexity involved that was inherited from the 8086 & 286 processors. Was a fantastic learning exercise... though I would suggest against using Pascal as the implementation language.
