• 10:3410:34, 31 July 2011 diff hist +8 Binary number What? No computer uses four-level (radix 4) logic internally? Only one counterexamople is needed to prove a claim of "all" false.

• 04:5204:52, 28 July 2011 diff hist +18 Diameter →Diameter symbol: Moved content irrelevant to this section to a new section. I also can't parse this sentence, but maybe someone else will know what it's meant to say and fix that.

• 13:2213:22, 25 July 2011 diff hist +38 X86 memory segmentation reflist
• 13:1913:19, 25 July 2011 diff hist +2,152 X86 memory segmentation restructuring and reorganization, to be more chonological and less intermix 80286 protected mode with 80386 and later protected mode, to be less confusing. Also, added a different (higher-utility) prespective on segment lengths in real mode.
• 12:1312:13, 25 July 2011 diff hist +275 X86 memory segmentation →Practices: refinement
• 12:0812:08, 25 July 2011 diff hist +449 X86 memory segmentation →Practices: changing CS in protected mode; in real mode

• 11:5411:54, 25 July 2011 diff hist +110 X86 memory segmentation →Practices: Paging unit--clarification of which processors have one.
• 11:5011:50, 25 July 2011 diff hist +290 X86 memory segmentation →Practices: ES; copy editing
• 11:3511:35, 25 July 2011 diff hist +488 X86 memory segmentation →Subsequent expansion: A20 gate; copy edits
• 11:1511:15, 25 July 2011 diff hist +339 X86 memory segmentation →Real mode: Added: why real mode addressing is limited to 2^20 bytes--8086 was a 40-pin DIP with 20 address pins (MUXed with data bus)
• 11:0311:03, 25 July 2011 diff hist +545 Memory segmentation →Intel segmented memory: clarified: protection on the 80286--real mode and protected mode
• 10:3510:35, 25 July 2011 diff hist −87 CSIRAC Corrected false claim of "last surviving". The reference [falsely] said it is the only one; the Pegasus is clearly a counterexample to the claim of "1 of only 2 surviving 1st-generation computers". Tag: references removed
• 10:1910:19, 25 July 2011 diff hist +541 History of computing hardware →Post-1960: third generation and beyond: NPOV clarification re: dispute about "the first microprocessor"; added connecting logic to make the sentence about the image to the right fit in context

15 July 2011

• 22:4822:48, 15 July 2011 diff hist +20 Orion (Constellation program) →Design: correction: the payload bay doors are a critical part of the shuttle orbiter; they are its heat rejection radiatiors, and serious damage to them would force a mission abort and prompt deorbit

9 July 2011

• 22:4522:45, 9 July 2011 diff hist +18 IBM PC keyboard →Invented for the PC: The Windows key and menu key were most recently added of all the standard US-layout keys in this list and are the least standard (most proprietary); they belong near the end of the list.
• 14:3214:32, 9 July 2011 diff hist +59 Space Shuttle →In culture: Lego Space Shuttle standard set

• 13:3913:39, 9 July 2011 diff hist +1 Martin Marietta X-24B →Operational history: The Space Shuttle program will be "today's Space Shuttle program" for only about 11 more days; might as well change it here now (lest I/we forget).

• 08:2208:22, 21 June 2011 diff hist −69 Whippletree (mechanism) →Mechanical analogue computers: deleted DAC mention--there is nothing analog in the type ball mechanism described; it is all digital (with some signal noise, just like all real digital systems).
