On this weekend the BIG hacker's festival, named "ChaosConstructions" is starting!
https://chaosconstructions.ru/
There are should be a lot of retro tech: #SunMicrosystem servers, some old #DEC stuff, #SunOS (or #Solaris ) terminals, PCs from Win95/98 era, etc. All hardware is working 
I was on the festival in the last year. Some photos from this festival are here: https://eugene-andrienko.com/photo/2024/09/01/summer-photos-2024.html (section "Computers").
So, on the next week(s) you (my subscribers) will be flooded by the photos of the various retro tech, sorry (but no sorry)
