After researching the source of this 7104 manual FEB 1989 I see that I did buy it from QSERVICE Nikolaos Kapetanakis for $US 9.49.
So I don't feel good at all in sending this PDF to anyone and/or making it available on TEKWIKI and I am NOT going to do this.
This is a great copy that took some time to scan and QSERVICE deserves to make money on this just like Artekmanuals.
I would ask all of you to go to QSERVICe at www.qservice.tv and pay him for a copy.
At least those of you who need this latest manual now know where to get a copy.
