I started off with the ZX81 too. From there I went onto the Amstrad CPC464, which I still have with colour monitor and twin disk drives. Along side the 464 in the loft I also still have my Amiga500, C64 and Vic20. Jetset Willy is still my fave game and after having it for somewhere around 25 years, I have still not completed the game. How many games can you say that about these days. A week or two of solid gaming and you have finished. I also have a spectrum emulator on the laptop with manic Minor, Jetset willy, spindizzy and codename mat on it.
