23:33 (cur | prev) +17 Josh talk contribs (House style: rephrase the corrections as statements about the facts rather than about this page's own history)
     
23:28 (cur | prev) 0 Josh talk contribs (Fix the remaining FFFFTTEE to FFFFEETT for consistency with the rest of the page)
     
23:27 (cur | prev) +552 Josh talk contribs (Verification drive: labelled as {{Original research}} per the wiki's own policy for native decoding work. 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...)

23:10 (cur | prev) +3,359 Josh talk contribs (Verification drive: the Apple SuperDrive and its 400K/800K predecessors are DIRECT DRIVE - no belt exists, and the 'check the drive belt' advice that propagated from here to several machine pages is removed; deleted the uncited head re-tensioning, track-zero sensor alignment and stepper head-alignment procedures (there is no felt pad in a double-sided 3.5in drive and Apple publishes no adjustment at all); removed HD SC Setup as a floppy tool; added Apple's 3.5 Drive performance and current-dr...)
     21:13  Macintosh LC 630 General Maintenance 2 changes history +5,278 [Josh (2×)]
     
21:13 (cur | prev) +1,713 Josh talk contribs (Battery section corrected: the '4.5 battery' in Apple's symptom chart is a section cross-reference, not a voltage - the same manual prints '5.4 battery' for the same step and the Performa 630 Series manual prints '5.4' in the identical entry. Apple names no battery part, voltage or threshold for this machine, so none is asserted; 742-0011 is still correctly excluded)
     
00:47 (cur | prev) +3,565 Josh talk contribs (Verified against Apple's LC 630/Quadra 630/Performa 640 Service Source (hosted). Corrected: board is 820-0548-B not 820-0524; battery part 742-0011 is the LC-series lithium and does not apply here; the LC 630 does have a fan (Apple documents a fan/video bracket and a 2-pin fan cable) so the 'no internal fan, convection only' section is removed. Deleted the invented rail tolerances, the PSU potentiometer step, the 4.0V battery threshold, the 3-5 year interval, the Rayovac part and the PIO Mode...)

21:07 (cur | prev) +2,897 Josh talk contribs (Rewrite against Apple's LC 630/Quadra 630/Performa 640 Service Source and the newly hosted Developer Note: DELETED 'passive cooling leads to heat accumulation' - Apple documents a fan/video card bracket (922-1160), a 2-pin fan cable and four symptom-chart entries that branch on whether the fan is running; dimensions corrected from 3.4x12.3x15.8 in to Apple's 4.3x16.5x12.6 in and weight split 17 lb / 19 lb with CD-ROM; sound corrected from '16-bit 44.1 kHz' to Apple's 8-bit stereo, 16-bit in C...)
     00:47  Macintosh LC 630 Capacitor Replacement Guide diffhist +1,464 Josh talk contribs (Board is 820-0548-B (Apple FRUs 661-0158/0189/1114/1115), not 820-0524. Capacitor count and values (6x47uF 16V, 3x100uF 6.3V) confirmed against Recap-a-Mac and retained; the C1-C3/C4-C9 designator assignment was fabricated and is removed - C3 is a 100uF and C41/C43 are 47uF. Deleted the invented rail tolerances and the PSU potentiometer adjustment (Apple documents neither) and the drill-the-pads through-hole conversion. Added Apple symptom data and part numbers; refs added; {{Unverified data}...)
