Chances are that you have never heard of the Sinclair QL. However if you are as old as me and European then you may have a soft spot for this 68k-based machine launched twelve days before that other 68k machine from the fruit company. It was my first 32-bit multitasking machine, with a real operating system (shame about the keyboard and storage device though).
I got one of the fruit company's 68k machines not long after the QL as an advance from my publishers and used it (running MacWrite 1.0)�for my two QL books (one of which is quoted on the wikipedia page!) and wrote assembly language code for both platforms. My University 3rd year project was a debugger for the QL and I wrote an assembler too, which eventually turned into HiSoft Devpac for the QL, Atari ST and CBM Amiga once I got a proper job. So I guess I can thank the QL for my decades of work in the�development tools�field.
My parents attic still contains my disassembly of one of the QL operating systems (FB I think), though I know they would like me to dispose of it and much of the other detris from my past, though my QL hardware stayed at HiSoft as I recall. I think I still have some microdrive cartridges somewhere.
For the nostalgic see this page�for the 25th Birthday rememberance, thanks for the info Urs, I would have no idea otherwise.
