Jim This is the first I have heard of a manual 901
as posted, the SD is as close as I have gotten along w/ the 510 manual
There are several members building there mods w/ 901's
I also noted that Eastmall has an 801 manual, which is now in my sights,
if anyone has the 801 manual, please review!!!
however, if you know of anything developing on the 901 manual, please direct us/me
thanks
