I still have my ps1 & ps2 and both work great, I have a Sega Megadrive but it's untested I don't have the cables for it lol.
My Gameboy Colors are my oldest handhelds I never had the OG model although I'd love to have one for collections sake.
@Megan you're lucky you have one!
@IV I think I also have some old floppy discs now you mention those! From my childhood I found them in my last clear up, god knows what's on them just says "pics" on them, probably google image search jpgs. lol
I still have all my old mobile phones too but dunno what works or not including early Blackberry and iphone models as well as a Sony Ericsson and a couple old Nokias and Samsungs. My brother even had a N gage, I think the first model, he sold it when he found out it held some value tho :/ I would've kept it if it was me haha
My dad used to have one of those cool old orange desktop mac computers too but I'm not sure if he still has it.
