The author, Michal Necasek, is certainly an expert on decompiling old binaries. He has reverse-engineered old copy protection system, patches old operating systems to run on modern systems or emulators, patches together broken installation disk images to make them work again, is frequently disassembling old programs to find out why they worked on older hardware and broke on newer ones, and more. Doesn't take long reading his site to find articles with such things.
