Most files are from the 8050 - 8250 Dual Disk Drive Service Manual, June 1985, PN-314011-03
That manual contained many triple width fold out pages. Most had a wide enough margin so that they could be scanned as a double width page. Those that could not are designated with a "l" for left and "r" for right parts of the page. All but page 13 could be split so that no information was cut in two by the split.
