Still got loads of stuff from when I was much younger. Arcade and computer wise my first pcb which I still have was Robocop if I remember correctly, I must've had it for over 25 years now I reckon. Still got the first computer we got back in the 80's, ZX Spectrum +, though it was more "the family's" but I used it 99.9% of the time. The ZX Spectrum +3 my parents got me a few years later I still have.
