Refreshingly nicely styled website for the QL, Dave.

Which of course SUCKS. Oddly, the QL manual that came with it refers to the EU style interfaces. Does anyone know the pinouts? I have now posted the photos and the correct URL is: http://www.nonstickglue.com/QL_Hardware_Library/Photos.html Over time I will add extensively to the photos and technical info on the site. You might want to bookmark it. Also, I will be creating a CURRENT list of maintained and active QL sites, which I will maintain to ensure it doesn't become a pile of dead links in a few months like many others :P Dave On Sun, Feb 13, 2011 at 4:15 AM, Tony Firshman <[email protected]> wrote: > Plastic wrote, on 13/Feb/11 06:57 | Feb13: > > Hi all. >> >> I have been looking at my US QL, and noting many differences from UK >> keyboards. >> >> Here's what I have seen so far.
