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...)

23:27 (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 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/30 diffhist +285 Josh talk contribs (Rebuilt against Apple SE/30 Service Source + Guide to the Macintosh Family Hardware: release date was 16 January 1986 (wrong; 19 January 1989), CPU 16.667MHz -> 15.667MHz, ROM 512KB -> 256KB, weight 19.5lb -> 21.5lb, RAM 128MB claim qualified against Apple 32MB; DELETED fabricated memory map, ROM module table, SCSI/sound path detail, JP13 and chess-tone easter egg; pseudo-slot video explained from Apple ch.12; chip location map from the hosted 050-0253-01 redraw; refs and reflist)

01:47 (cur | prev) +470 Josh talk contribs (Removed unsourced rail tolerance table (+5V 4.90-5.15, +12V 11.9-12.7) and the R56 trimmer adjustment: Apple's Classic/Classic II Service Source publishes no rail figures and its Adjustments chapter covers video only. Added Apple's actual Electrical spec (100-120 VAC, 47-63 Hz, 100 W max))
     02:15  CRT Discharge Procedure 2 changes history +11,081 [Josh (2×)]
     
02:15 (cur | prev) −45 Josh talk contribs (Remove self-referential wording per house rule)
     
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)
