Probably a breadbin C64 I’d say.

In terms of actual age, I have a light-sixer Atari 2600.

In terms of the oldest thing that I bought originally, it’s a lot more recent - probably Tomb Raider on the Playstation from 1997. I sold so much of my original 80s and 90s stuff, or traded, or just plain lost it. I regret this massively.

If I could offer one piece of advice to people growing up, I’d probably steer clear of stuff like “don’t do drugs” or “stay in school” (they can get all that from Grange Hill). Instead, I’d say - don’t part with your most cherished memories. You might think you need that fifty quid now, but they’ll be worth so much more to you later on.

Don’t have it yet but I have bids on a 1978 Space Invaders Arcade PCB for my streams etc but right now its the ZX80. Nearly bought a Adman Grandstand T.V. Game 2000[ from 1977, same one I had in '77 but realised it would just be shelf material and I prefer using the systems.
