• 09:3009:30, 24 July 2011 diff hist +2,674‎ Microprocessor ‎ →‎16-bit designs: Intel: added 80188 and coprocessor options and made some copy edits. See Talk page re: 8086 segmentation (shortly)

• 21:4721:47, 17 July 2011 diff hist +20‎ Top Gear series 12 ‎ →‎Episodes: correction

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

• 13:4313:43, 9 July 2011 diff hist +1‎ Dick Scobee ‎ copy edit
• 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).

1 July 2011

• 10:3910:39, 1 July 2011 diff hist +3‎ Space Shuttle program ‎ →‎Other STS program vehicles: copy edit

30 June 2011

• 10:3610:36, 30 June 2011 diff hist +415‎ Composite video ‎ →‎Signal modulation: clarification: color-under is more than a slight modification of NTSC composite
• 10:2610:26, 30 June 2011 diff hist +849‎ Composite video ‎ →‎Signal components: This is not your father's FDM.
• 10:1410:14, 30 June 2011 diff hist +43‎ Composite video ‎ →‎Signal components: QAM
• 09:4509:45, 30 June 2011 diff hist +17‎ YPbPr ‎ →‎{{YPbPr}} Advantages: Copy edit: "the only one out of the other two" was a nonsensical phrase.
• 09:4209:42, 30 June 2011 diff hist +15‎ YPbPr ‎ →‎{{YPbPr}} Advantages: YPbPr /is/ component video, but not the only kind of component video

25 June 2011

• 22:0222:02, 25 June 2011 diff hist +10‎ Car rental ‎ →‎Rental conditions: Added "sometimes" to mileage limits; many car rentals include unlimited miles

21 June 2011

• 08:3208:32, 21 June 2011 diff hist +497‎ Whippletree (mechanism) ‎ →‎Mechanical analogue computers: added mention of a relevant mechnical computer on exhibit at The Franklin Institute
• 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).

• 19:4119:41, 4 June 2011 diff hist 0‎ Template:Space Shuttles ‎ ordering
• 19:3619:36, 4 June 2011 diff hist +15‎ STS-135 ‎ →‎Rollout
• 19:3419:34, 4 June 2011 diff hist +30‎ STS-135 ‎ →‎Rollout: grammar in caption
• 19:2319:23, 4 June 2011 diff hist +603‎ STS-135 ‎ →‎Payload: added footnote about impossibilty of simple continuance of the space shuttle program

3 June 2011

• 00:5900:59, 3 June 2011 diff hist +164‎ TI-81 ‎ →‎Features of the TI-81: not all TI-81's have the backup battery (mine, bought new for $99 circa 1992 and still in service, doesn't; the spot where it would be is occupied by a molded-in filler that looks like a bullseye)

• 13:0613:06, 2 June 2011 diff hist −80‎ Byte ‎ Undid revision 432170031 by 74.109.5.17 (talk) reverting my own edit. (Where does that 12th bit come from?)
• 13:0413:04, 2 June 2011 diff hist +80‎ Byte ‎ →‎Common uses: derivation of 12-bit maximum
• 12:2012:20, 2 June 2011 diff hist −262‎ Racetrack memory ‎ →‎Description: removed core memory, which is irrelevant here, and corrected the sentence about "'push[ing' a magnetic pattern through a substrate"; delay line memories (e.g. mercury) usually involve no magnetic pattern, but a mechanical wave.
• 11:5811:58, 2 June 2011 diff hist −177‎ Wired logic connection ‎ OK, now I actually did deleted the "Wired NOT" section, instead of just explaining the cause for its deletion in an edit summary. ;) Tag: section blanking
• 10:1610:16, 2 June 2011 diff hist +8‎ Schottky transistor ‎ →‎Operation: clarification--what "standard" diode?
• 09:5709:57, 2 June 2011 diff hist +58‎ Schottky diode ‎ →‎Reverse recovery time: parenthetic clarification of "nothing to recover from"

• 10:1910:19, 1 June 2011 diff hist +1,134‎ IBM Personal Computer ‎ →‎Electronics: Rewrite of system chips secction. Much better, but could still be improved further. The I/O addresses of the chips would be better listed separately in a table.
• 09:4509:45, 1 June 2011 diff hist +18‎ IBM Personal Computer ‎ →‎Electronics: correction
• 09:4409:44, 1 June 2011 diff hist +275‎ IBM Personal Computer ‎ →‎Electronics: explanation of expansion slots--don't assume the reader knows

• 09:1609:16, 1 June 2011 diff hist +4‎ IBM Personal Computer ‎ →‎XT/370: copy edit
• 09:1509:15, 1 June 2011 diff hist +1,047‎ IBM Personal Computer ‎ →‎Models: improvements in details added to the paragraph about compatibility; clarification of "floppy disk" (many younger people would assume "floppy disk" means 3.5-inch floppy); copy edits and general minor improvements

• 11:3511:35, 20 May 2011 diff hist +41‎ Arc-fault circuit interrupter ‎ →‎Electrical code requirements: commonly understood and accepted understanding of this code section specifying just "outlets" instead of "receptacle outlets"
