Fixed internal inconsistencies: the expanded line-1 layout is FFFFEETT not FFFFTTEE (the page's own worked example, the extended exception list and the decoder gadget all put the exception in the upper byte of the lower word); the intro example called RAM Bank A test 03 when the page's own table makes it 04; the per-ROM checksum Test Manager command was given as test 04 (RAM Bank A) rathe...) | ||||

The logic-board table said C1-C10 47uF and C11 1uF; the real 820-0260 list is C2 470uF 16V axial, C6 1uF 50V, C11 220uF 16V axial and ten 47uF 16V - the two axials were missing entirely.

Logic board caps were given as 33uF 10V; they are 16V, and the designators were wrong. Removed R56 - the SE has no voltage adjustment.
