Mar 12th 2009 – SINCLAIR QL Preservation Project (SQPP) launched as part of the "QL is 25" activities, starting with documents/publications from Sinclair Research Ltd and various computer magazines of the years 1984 to 1986. To learn more about all that please check out the full 25th anniversary story.


25 years is a long time in life and a very long time in ICT. Another 25 years and almost certainly all QL related know-how (software, hardware, paperware and any brainware) will be lost forever if no measures will be taken today. Another good reason for doing this project is to clean out my attic and shed to get more space for non QL related stuff.


During 2009 I was able to use a powerful Xerox WorkCentre 7655 AIO for a few months to produce high quality scans in both JPG (pictures) and searchable PDF (documents) formats. Equipped with a new digital camera (Panasonic LUMIX DMC-TZ7) in summer 2009, I was able to produce high quality still pictures as well as HD videos (1280x720 pixels). Later on (2010 onwards) I started to use a HP Photosmart Premium AIO to scan the printed material. In 2012 and 2013 I upgraded my cameras to a Full HD equipment consisting of a Panasonic LUMIX DMC-TZ31 and a Panasonic LUMIX HC-V727. The same year I've bought an Epson WorkForce WF-7525 AIO which offers an A3+ scanner.


Since autumn 2009 I use a spare room in my offices of the Lake Valley Labs for my Retro Computer and Videogames collection. I'm calling this room the Lake Valley Retro Labs.

    First idea was to host the files for download on my cowo.ch domain. Still some files are hosted there. Most stuff is now in the Repository of my sinclairql.net domain. Soon after I have started with SQPP, I did realise that for several reasons (webspace, convenience, ad hoc uploads, comments, etc.) it is wiser to use existing web 2.0 based community platforms. I decided to go with Microsoft's OneDrive (fka SkyDrive) Photo Gallery and Storage cloud services for the Sinclair QL Picture Gallery (SQPG) and Google's YouTube online services for the QLvsJAGUAR Video Channel. With those services updates/additions are very easy and space is almost unlimited.

    QL forever!
