I think this is the most time-standing IT book that I own. It was published in 1999 and I still check it from time to time.
E.g. when collaborating with hpa on arch/x86/realmode
, this book was my main reference in addition to ELF specification.
It is also as prose very nice reading with cool stories embedded!
A recent #Amiga demo "Backslide to Arcanum" by Cosmic Orbs included a mind-blowing fullscreen 50Hz rotozoom effect on Amiga 500. Having created a rotozoomer on A500 back in the day I knew exactly how incredibly hard it is to make such routine run fast. The effect has now been dissected and there's also author's writeup.

Back in 1982, I was pouring over these adverts..
