| 10:43 | IBM PC XT Troubleshooting Guide diffhist −643 Josh talk contribs (Structural and content repair: remove emoji from section headings; merge the duplicated References section (the trailing bare bullet list is now named inline refs); de-duplicate the tripled/quadrupled ref definitions that produced visible cite errors; rewrite the bolted-on power-supply and CMOS blocks so they describe this machine (the Dallas DS1287/DS12887 claim and, where applicable, the PC/XT minimum-load sentence did not apply here)) | ||||

| 22:08 | IBM PC XT/370 diffhist +3,544 Josh talk contribs (Fix refs so they render; IBM fits TWO cards not three - PC/370-P in slot 4 and PC/370-M in slot 3, with PC/3277-EM only on older machines and the 3278/79 or Remote Display Terminal adapter as alternatives; add IBMs model numbers (5160 Models 568/588/589), the 10 MB vs 20 MB fixed-disk configurations and IBMs unit specifications; host link is coax not twinax) | ||||

Corrections: all four rail ranges were wrong; PSU is two separate supplies not switchable; 1701 is generated by the controller BIOS ROM; removed fabricated claim that 1986 BIOSes turn a C800 ROM fault into 1-long-2-short beeps; Xebec 1210 corrected to IBM Fixed Disk Adapter (built by Xebec); slot 8 1801 error applies to accelerator cards; head cl...) | ||||

Corrections: dimensions/weight replaced with IBM figures (498x411x147 mm, 14.2 kg) instead of Wikipedia approximations; "Xebec 1210 MFM controller" corrected to IBM Fixed Disk Adapter (built for IBM by Xebec); slot 8 1801 error applies to accelerator cards; 1986 BIOS caveats named; removed unsourced "eXtended Technology" and "5160-788 only XT with CGA" claims; 3270 PC and XT/286 moved out of the 5160 submod...) | ||||

Corrections: SNCTOL means "solder new capacitor to old legs"; post-recap voltage table was fabricated - replaced with IBM regulation tolerances and sense levels; removed invented ripple limits; PSU is two separate 120V and 220/240V units, not one switchable unit; 1701 comes from the HDD controller ROM not the motherboard POST; added 2-legged vs 3-legged footprint rule; dropped inc...) | ||||
