My first computer was a Timex 2068, which would be replaced by the latest ZX Spectrum 128K +2A (already produced by Amstrad and not Sinclair). This lasted until it was replaced by a Commodore Amiga 1200 and later with a Amstrad PCMM 512K!
To celebrate the 30 years, there is a new speccie comming out! I know I will grab one from the shelves once it hits! Something to remember.
