Started with a 48k issue 2 Spectrum, then bought a 128k+ the moment it came out in the UK in February 1986. I still have my 128k+ and it still works. I first encountered a ZX Spectrum emulator in 1990 or 1991, whilst still working (as a project manager/producer) on ZX Spectrum games! The emulator was JPP for the 286 IBM PC, had just five options and they were all in Spanish. Ended up registering the great DOS-based Z80 emulator (and then the WinZ80 version) and have used and registered most of the others since then.
