     08:54  Capacitor Failure Symptoms diffhist +1,692 Josh talk contribs (P4 verification: add worked examples of ESR-rise and RIFA failure from the two hosted Pina books, with the U.S./International designator warning)
     08:50  Macintosh SE diffhist +912 Josh talk contribs (P4 verification: cite Apple's own Service Source volume for this machine (hosted here) for the electrical specification and battery threshold, and link the documentation page)
     08:48  Macintosh SE Capacitor Replacement Guide 2 changes history +2,118 [Josh (2×)]
     
08:48 (cur | prev) +3 Josh talk contribs (P4 verification: rename a duplicated ref name so the citation renders)
     
08:47 (cur | prev) +2,115 Josh talk contribs (P4 verification: add a component-level sources section: Apple's module-level manual and Pina's SE analogue-board and CRT-socket-board parts lists, both hosted here)
     08:44  File:The Dead Mac Scrolls 1992.pdf diffhist +1,098 Josh talk contribs (P4 verification: real summary, page count, file size, source note and honest licence block for a File: page that was empty or 'MsUpload')
     08:01  Macintosh Classic II diffhist +661 Josh talk contribs (cite the hosted Service Source volume and what it settles (P4 orphan fix))

     23:33  Sad Mac Error Codes 3 changes history +569 [Josh (3×)]
     
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...)
     23:30  Sad Mac Decoder 2 changes history +651 [Josh (2×)]
     
23:30 (cur | prev) +164 Josh talk contribs (Add the Sad Mac illustration to the decoder page)
     
23:27 (cur | prev) +487 Josh talk contribs (Verification drive: labelled as {{Original research}}; spelled out the FFFFEETT layout so it matches the Sad Mac Error Codes page and the gadget's own parsing; added 512Ke to the short-format model list to match the gadget; noted that the chimes are synthesised rather than sampled)
     18:18  Macintosh Classic II diffhist −1,624 Josh talk contribs (Rebuilt against Apple Classic/Classic II/Performa 200 Service Source: DELETED fabricated memory map, V8 Lite/MEMCjr chipset claims, 53C96 and Egret attributions, ROM module table, MacBench comparison table, Paris codename/Eiffel silkscreen, JP3 debug jumper and the cold-start easter egg; SIMM speed 80ns -> 120ns or faster, single SIMM claim corrected to a pair, dimensions/weight/model number corrected; region-specific analogue board warning added; release_date parameter fixed; refs and reflist)
     18:18  Macintosh Classic diffhist −586 Josh talk contribs (Rebuilt against Apple Classic/Classic II/Performa 200 Service Source: DELETED fabricated memory map, ROM SIMM module table, SWIM-II/53C80 detail, MacBench benchmark table, Seattle/LittleFish codenames and MacsBug easter egg, and the 512KB 32-bit-clean/HFS+ ROM claim; CPU 8MHz -> 7.8336MHz, ONE ADB port (not two), Apple dimensions and 100W; predecessor SE/30 -> SE; added the real Command-Option-X-O ROM disk; fixed red link to a nonexistent Troubleshooting page; release_date parameter fixed; re...)
     18:17  Macintosh SE diffhist −4,570 Josh talk contribs (Rebuilt against Apple Macintosh SE Service Source: DELETED fabricated memory map, ROM v5.3-v5.6 table, PDS card list, RC filter values, environmental table, 150W max power, 1.5 million units and the ROM easter-egg address; Apple specs added (100W max, 90-140/170-270VAC, 17-21lb, four-voice sound); three-assembly construction (analogue board + separate PSU + video board) documented; FRU/board numbers; release_date parameter fixed; refs and reflist)

     02:15  Capacitor Failure Symptoms 2 changes history +12,684 [Josh (2×)]
     
02:15 (cur | prev) −40 Josh talk contribs (Remove self-referential wording per house rule)
     
02:07 (cur | prev) +12,724 Josh talk contribs (Rewrite with full citations (Nichicon CAT.8101H hosted here, Vishay 40110, KEMET F3011): corrected 60 Hz hum to twice mains frequency, corrected bulging mechanism to Nichicon gas generation, added missing film/X2 suppression section, added tantalum derating 60-50 percent, added Class II ceramic DC-bias behaviour, replaced Japanese-brand rule with no-datasheet-no-purchase, replaced IPA-only cleanup with Nichicon soap-and-water plus never acidic/alkaline, replaced reforming folklore with Nichic...)

02:05 (cur | prev) +11,126 Josh talk contribs (Rewrite against Apple Service Guide 1990 and Goldwasser CRT notes: corrected earth-return point (ground lug, never logic board), added never-wear-a-wrist-strap rule and implosion/goggles hazard, replaced unsourced 25 kV blanket with sourced per-class figures, replaced dead-short tool with resistive tooling, removed invented 30-min wait / 10-s hold / 10-15-min re-discharge interval, added ongoing shorting lead and aquadag mechanism; full ref citations)
     01:36  Battery Explosion, Capacitor or Corrosion Damage diffhist +12,961 Josh talk contribs (Verification drive: corrected chemistry (Li-SOCl2 half-AA neutralised with bicarbonate not IPA/water; capacitor electrolyte washed not neutralised - no published pH); added cadmium hazard for NiCd; added damaged-cell handling section incl. accurate lithium fire guidance; fixed +5V range 4.75-5.25 V; corrected United Chemi-Con/Nippon Chemi-Con and OS-CON/Panasonic; removed arbitrary '100 ohm' rail threshold and Kapton '400C' claim; added IEC 60086-1 cell designations; all figures now <ref>-cit...)
     00:13  Macintosh SE Capacitor Replacement Guide diffhist +10,759 Josh talk contribs (Verification drive: the 24-row analogue-board table was the Macintosh Plus power/sweep board list and does not apply to the SE at all - the SE uses analogue board 630-0147 plus a SEPARATE power supply module (three variants). Logic board caps were given as 33uF 10V; they are 16V, and the designators were wrong. Removed R56 - the SE has no voltage adjustment. Added Apple FRU numbers, electrical specs, the 2.8V battery threshold, and Pina component-level analogue-board faults from the hosted De...)
