      23:07  Macintosh Performa 5420CD 2 changes history +2,606 [Josh (2×)]
     
23:07 (cur | prev) +38 Josh talk contribs (Remove red link to a Power Macintosh 5500 page that does not exist yet)
     
23:07 (cur | prev) +2,568 Josh talk contribs (Verification drive: Apple says the 5420 is a GRAPHITE-COLOURED Power Macintosh 5400/120 sold initially in Japan - the difference is the plastics, not a software bundle; 8 MB soldered not 16 MB standard; width/depth were swapped; sound input is stereo not mono; removed the unsourced 40 MHz bus figure; separated out the distinct Performa 5420/180 (603ev at 180 MHz, Japan and Australia); added CRT, video-mode, cache-DIMM and electrical specs; fixed red link to Power Macintosh 5500)
     23:05  Macintosh Performa 6200 diffhist +3,165 Josh talk contribs (Verification drive: width and depth were swapped (Apple: 16.5 in wide, 12.6 in deep); the 1 MB frame buffer is dedicated DRAM on the logic board, not carved out of system RAM; added Apple's Repair Extension Program checks (U10 343S1191/343S1121, Cache/ROM DIMM 661-1278, U6/U27 version-B check, RGB cable) and the electrical spec; cited to the Performa 6200/6300 Service Source)

23:04 (cur | prev) +5,310 Josh talk contribs (Verification drive: the 1 MB frame buffer is dedicated DRAM on the logic board, not shared system RAM; added Apple's Repair Extension Program checks (U10 343S1191/343S1121, Cache/ROM DIMM 661-1278, U6/U27 version-B check, RGB cable 922-2357) and Open Transport 1.1.1; added CRT, video-mode and electrical specs; explained Apple's self-contradictory published weight; cited to the 5200/5300 Service Source)
     21:13  Macintosh LC 630 2 changes history +4,356 [Josh (2×)]
     
21:13 (cur | prev) +1,459 Josh talk contribs (Battery section corrected: Apple's '4.5 battery' is a section cross-reference, not a voltage - the same manual prints '5.4 battery' for the same step and the Performa 630 manual prints '5.4' in the identical entry. Apple documents no battery part number, voltage or threshold for this machine, so none is asserted)
     
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...)

21:02 (cur | prev) +9,736 Josh talk contribs (Rewrite against Apple's Macintosh II/IIx/IIfx Service Source and the newly hosted Apple Technical Note HW 9, plus Recap-a-Mac's board photograph, MacDat and Console5. Corrections: height 5.5 in not 5.8 in; model number M5525 not M5780 (M5780 is the IIci); price US$8,970-10,970 not $8,969-12,000. DELETED the unsourced capacitor list (10x47uF/4x10uF 25V/2x220uF/2x470uF 25V/1x1000uF) and replaced it with the real complement, 14x47uF 16V + 3x470uF + 1x220uF + 1x10uF + 1x1000uF 10V, corroborated t...)

     18:20  Macintosh Color Classic II diffhist +1,250 Josh talk contribs (Rebuilt: DELETED invented Known Revisions and Errata (marginal 5V regulation/improved 7805, swapped C6/C7 footprints), the US MSRP (never sold in the US), stereo line-out and 2.5x performance claims, and successor = LC 520/Performa 275 (Performa 275 is the same machine); memory now states both published answers - Apples own Service Source repeats the Color Classics 10MB/two 30-pin J10 page verbatim while independent sources and the LC 520/550/575 manual give 36MB via one 72-pin SIMM - with a...)
