Looks like you posted about getting several different manuals for older machines. A place to find many manuals is:
http://www.coinslots.com/manuals/Also, there are many manuals and documents in the NLG download area. The NLG website is setup so that nearly all discussion forums are available to anyone for free but for access to the download area you will need to support NLG by making a contribution (small or large, one-time or continuing, all is appreciated). This will also give you the ability to post items for sale in the Classified Ads area and unlimited personal messages (pm's) on the website.
If you've already donated and became an NLG member then you should be able to download. If you aren't able to then contact someone on NLG staff and they can get you setup.(click image to enlarge)
If you'd like to help NLG stay available by being a contributing member look on the Home Page for this panel:
