I must admit, I was very skeptical... $4.99 for a 74 page service manual. I've seen some very poorly scanned manuals on the Internet, but this one is VERY good quality! Even when zooming into 500%. Great Deal!
Thank You for fast delivery for the sheme.
Everything allright.
Thanks & best regards Franz
