I inherited a Smith-Corona Memory Typewriter SD700 and am having a difficult time trying to use it. I found a manual online which might be close to my typewriter, how do I download or copy that information which I need to get the basics of this machine? I got a screen pop up regarding PDF Adobe something or another, join and pay $15.00 a month for some such jazz - I just need some basic info on getting basic typing done...I don't want a membership to anything. Can someone help please?
