I have 1x CPC464 - That's the one that started me off, although it's not quite the original machine from childhood, I only bought one recently and it's undergoing repair.
1x 6128+ for playing games that cater for additional Plus features.
1x GX4000. For the sake of having it, and plugging a C4CPC. It's also due a minor repair as the pins literally fell out of joystick port 1!
M4, HxC, C4CPC, ZMem and MFII clone to use on both the 464 and the 6128+. I think I'm pretty much sorted in terms of Amstrads now.
