The Sinclair QL is 25 yrs old today!
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.
