Some guy scanned the Neuromancer comic book and put it online. Unfortunately the images of the englich version are small but still readable, the german version was scanned in much better resolution.
It says "book 1" one he cover, but as far as I know, there was no second volume.
There's three books that form the sprawl series: Neuromancer, Count Zero and Mona Lisa Overdrive. They were all released in the 80s, and although they're quite entertaining, they don't seem to carry on the originality of Neuromancer
