  Computer science would not be the same without personal computers. In the
West the so called PC revolution started in the late '70s and has its roots in
hobbyists and do-it-yourself clubs. In the following years the diffusion of
home and personal computers has made the discipline closer to many people. A
bit later, to a lesser extent, yet in a similar way, the revolution took place
also in East European countries. Today, the scenario of personal computing has
completely changed, however the computers of the '80s are still objects of
fascination for a number of retrocomputing fans who enjoy using, programming
and hacking the old 8-bits. The paper highlights the continuity between
yesterday's hobbyists and today's retrocomputing enthusiasts, particularly
focusing on East European PCs. Besides the preservation of old hardware and
software, the community is engaged in the development of emulators and cross
compilers. Such tools can be used for historical investigation, for example to
trace the origins of the BASIC interpreters loaded in the ROMs of East European
PCs.
