Hey, portuguese people!
There are only three locations listed in retro.directory for Portugal. If you know of retro stores, exhibitions, arcades, events, points of interest, ..., go there and add them.
Portugal wasn't much of a fertile ground for home computing in the decades of yore due to the weak economy coming out of a dictatorship, but I'm sure there's stuff around here now. We're just not very good at promoting it.
