The plan is to re-introduce the missing guides with new pictures and info. just right now i'm working with the Ann Arbor pinball museum getting ready for the 300 restored game pinball show May 13-15 http://www.vfwpinball.com . That is taking priority and a lot of time. After the show things should calm down and i'll get the system80 guide back up, and then follow with Bally -17/-35. The Williams/dataeast stuff will take the most time unfortunately.
I would like to made the ninja thing a freebie again too. but it just takes so much time to do the words, the photos, and the videos, it's hard to justify that position. There are almost 400 repair videos and nearly 900 repair logs at that site. it's quite a body of work.
