I have used various 'retro' computers from the ZX81, Acorn Electron, Commodore 64, ZX Spectrum and Amstrad CPC464 and CPC6128 on to the Playstation and Gamecube. I have also worked as a computer programmer, working on everything from S/390 mainframes, HP-UX and AIX, OS/2 v1, MS-DOS, Windows 3.0-98 and Linux, in Pascal, C, C++, Delphi, Logo, JCL and various others. I still own an Amstrad CPC6128.
