I was hunting for information for my ZX7 and always found Andy's site very helpful with heaps of info. The website is gone now but I found a link to the historical information that used to be on there thanks to ZXForums.com

This was the old link - http://homepage.ntlworld.com/webzxr/zxr750r/index.html
but you can find most of the info here at https://web.archive.org/web/20120112...50r/index.html
To navigate you have to use the little left/right scroll thingy at the bottom on the left side of the home screen. Hope this helps
Cheers
