• 08:4008:40, 18 May 2021 diff hist +141‎ Zilog Z80 ‎ →‎Instruction set and encoding: added detail: 8080 I/O is not only limited to register A but also to a direct (immediate) port address, no variable port

• 07:4907:49, 18 May 2021 diff hist 0‎ Zilog Z80 ‎ →‎History: clarified "special reset": the function is actually called "special reset"; it is not merely a reset function that is special in some way, but it is a second reset function in addition to the normal reset function.
• 07:4407:44, 18 May 2021 diff hist +17‎ Zilog Z80 ‎ →‎History: clarified Faggin's specialization
• 07:4207:42, 18 May 2021 diff hist +992‎ Zilog ‎ →‎Z80: clarification: Everyone thinks the Z80 in the Genesis is for sound, but it's not at all limited to that function--neither by engineering intention nor by Genesis system hardware design
• 07:1907:19, 18 May 2021 diff hist +483‎ Zilog ‎ →‎Z80: 1) copy edit to clarify an apparent literal ambiguity about which CPU was "faster, and much cheaper", and correction of partially misleading text. 2) addition of DEC Rainbow 100, Z80/6502 popularity details including current active production, and other minor details

• 07:0707:07, 13 May 2021 diff hist −1‎ TRS-80 MC-10 ‎ →‎Description: copy edit--grammar

12 May 2021

• 10:3810:38, 12 May 2021 diff hist +13‎ Data General Nova ‎ →‎Design of the Nova: clarification--strictly, a stored-program ("von Neumann") digital computer does not have to have a general arithmetic or logical function unit at all, but could just have a program counter incrementer and single-bit test and compare capabilty, and could still be Turing-complete.
• 07:4107:41, 12 May 2021 diff hist +50‎ Flip chip ‎ clarified wire bonding
• 07:0707:07, 12 May 2021 diff hist +1‎ PDP-14 ‎ copy edit--better word choice. "drawback" is not the right word; if "adversity" is also judged inadedequate, perhaps "challenge" is better.

11 May 2021

• 08:0208:02, 11 May 2021 diff hist +19‎ Commodore PET ‎ →‎Release: It appears much more likely that the BIOS component of CP/M-80 is the true predecessor of the IBM PC ROM BIOS.

• 01:0201:02, 3 May 2021 diff hist +1,379‎ List of TRS-80 and Tandy-branded computers ‎ →‎PC-compatible computers: section semi-rewrite
• 00:1200:12, 3 May 2021 diff hist −5‎ TRS-80 ‎ →‎Development: clarification--the original text (that I just edited) does not make clear that French, and no Roach (or someone else), actually was the person who hired Leininger
• 00:1000:10, 3 May 2021 diff hist −8‎ TRS-80 ‎ →‎Development: copy edit--corrected corrupt grammar/usage
• 00:0500:05, 3 May 2021 diff hist +84‎ TRS-80 ‎ Changed "RadioShack" to "Radio Shack" everywhere; it was 2 words during the time that the TRS-80 was developed, manufactured, and marketed, and during the entire time that the TRS-80 brand was used. RadioShack emerged in the 1990s.

• 23:2823:28, 2 May 2021 diff hist +2‎ TRS-80 Model 4 ‎ Radio Shack was 2 words during the time that the TRS-80 Model 4 was developed, manufactured, and marketed
• 23:2223:22, 2 May 2021 diff hist +1‎ TRS-80 Model II ‎ Radio Shack was 2 words during the time that the TRS-80 Model II was developed, manufactured, and marketed
• 23:1923:19, 2 May 2021 diff hist +3‎ TRS-80 ‎ corrected TRS-80 expansion: Radio Shack was 2 separate words when the TRS-80 brand was active; the fusion to "RadioShack" occurred as a desperate marketing ploy in the 1990s. Note also that I have read another (inside?) source that claims TRS-80 signified "Tandy/Radio Shack for the [modern] 1980s".
• 23:0823:08, 2 May 2021 diff hist +1,058‎ Zilog Z80 ‎ →‎Embedded systems and consumer electronics: clarified Sega Genesis Z80 usage and capabilities; added TI-8x graphing calculators
