Has anyone found any service info on the Atari System II boards beyond the basic schematics and patent #4930074 filed in 1986 (thanks to Jed Margolin for the link - http://www.jmargolin.com/patents/atpats.htm)? I have a Paperboy that only shows about 8 'Motion Objects' instead of the 39 that are supposed to be there. All other tests pass fine. Motion objects are blocky and continuously break up. All the 6116s test out fine on the video board, ran them through my standalone RAM tester (RAMTek). The patent looks like my best shot - printing it out and read that. Thanks, John :-#)# -- How to subscribe or unsubscribe from TTL http://seven.pairlist.net/mailman/listinfo/techtoolslist _______________________________________________ Techtoolslist mailing list Techtoolslist@flippers.com https://pairlist7.pair.net/mailman/listinfo/techtoolslist FTP site is: ftp://ttl.arcadetech.org/TTL/Test_Equipment Archive site: http://seven.pairlist.net/pipermail/techtoolslist/
