ZX Spectrum was one of the Engineering and technology good articles, but it has been removed from the list. There are suggestions below for improving the article to meet the good article criteria. Once these issues have been addressed, the article can be renominated. Editors may also seek a reassessment of the decision if they believe there was a mistake.

ClarificationEdit

There's a sentence at the end of the +3 section

The +3 was the final official model of the Spectrum to be manufactured, remaining in production until December 1990. Although still accounting for one third of all home computer sales in the UK at the time, production of the model was ceased by Amstrad at that point.

Reading it, one might get the impression that the +3 was "the model" referred to that "accounted for one third of all home computer sales" and which was discontinued. I'm almost certain that this is misleading phrasing and, if correct (and a citation would be nice too), it's *meant* to refer to the Spectrum family as a whole. Right?

Without a source, who's to say? These kind of statistics really need sources. Letdorf (talk) 11:31, 20 September 2010 (UTC).
According to this reference - [11] which is a reputable source, sales of the +3 were halted in December 1990, but the +2 continued. I will change the main article.203.26.122.12 (talk) 07:02, 5 April 2011 (UTC)
Note that that quote says "The +2 will continue" but it refers to the +2B, not the original +2. — Preceding unsigned comment added by 87.243.208.102 (talk) 16:10, 2 June 2011 (UTC)
I'm pretty certain the original +2 was discontinued with the 2A coming in because the cassette drive was of very poor quality with a very small capstan wheel and many were returned to stores as they failed to load programs.101.178.163.92 (talk) 03:38, 16 March 2018 (UTC)

"Basic fact checking"Edit

With regard to this edit summary, my response is that "Basic Fact checking" is to be done by the inserting editor, not the removing editor. If you want to add valid references then that's fine, but do not presume to tell me that it's my job to do so, just because I removed some unsourced info, especially when part of said info relates to Timex Sinclair which relates exclusively to the American variants of the Sinclair range - this is clearly the wrong link, and I've changed it, again.

I'll also be pedantic and mention that the source is not entirely accurate - the Spectrum was not "£145 with extra RAM", but either £175, or £129 - I assume based on the articles claim of £125, that it means £179 and it's just a typo. Chaheel Riens (talk) 17:37, 12 November 2016 (UTC)

Just because someone has added unsourced information does not mean you should immediately revert it. It is very discouraging to new editors. Please see - Wikipedia:Reverting#When_to_revert. MrMajors (talk) 18:14, 12 November 2016 (UTC)
That's an essay not a policy, and while you may follow it if you wish - I am under no obligation do to do. You may hold whatever opinion of me you want - I don't care - but don't presume to dictate to me just because I removed incorrect information from an article - which you then reinstated, albeit probably unintentionally.

MicrodivesEdit

"it never took off as a distribution method due to worries about the quality of the cartridges and piracy"

The principal problem was the cost of writing onto the cartridges. Software distributors used the same recording machinery as was used for audio cassettes with cassettes. Conventional disks had similar problems to microdrives for prerecording, that's why they cost so much more than cassetttes, they were usually recorded by hand. Microdrives were too slow for that.101.178.163.92 (talk) 02:45, 17 October 2017 (UTC)

Sinclair Research originally intended the Microdive to be used with ROM cartridges, the Interface 2 (which you needed to use the Microdrive) had a ROM cartridge connector. You would plug in a ROM cartridge such as a word processor, and only use the microdrive to save files. The idea never took off because of the 16 kB limit of ROM cartridges (a problem which was not economically overcome until a few years later), the association of ROM cartridges with games consoles, and the public obsession with diskette drives.101.178.163.92 (talk) 03:45, 16 March 2018 (UTC)

Make sense. If I recall correctly, the Microdrive required an Interface 1, not 2 - Interface 2 was only for joysticks and ROM cartridges, which would tend to reinforce the assumption that cartridges are for games. To use a ROM cartridge with a Microdrive you'd have to buy both interfaces (and have one sticking out of the other). Pastychomper (talk) 15:22, 29 March 2018 (UTC)

MemoryEdit

""The Z80 processor used in the Spectrum has a 16-bit address bus, which means only 64 KB of memory can be directly addressed. To facilitate the extra 80 KB of RAM the designers used bank switching so the new memory would be available as eight pages of 16 KB at the top of the address space. The same technique was used to page between the new 16 KB editor ROM and the original 16 KB BASIC ROM at the bottom of the address space""

It is the 8 bit processor which limits the amount of memory which can be addressed, not the address bus, which can be latched (as in the IBM PC). And I'm fairly sure because of the kernal and the way the pins on the Z80 are tied up, only 48 kB can be accessed in the Spectrum. I believe the extra memory on the +2 is accessed by paging in 16 kB at a time and swapping the original contents out "high" above 48K, using the offset addressing method available on the Z80.101.178.163.92 (talk) 04:02, 16 March 2018 (UTC)

Talk page archivingEdit

I've archived threads from this page, it's been 10 years, I thought it was about time. Have archived anything over 2 years or where the discussion had been closed. - X201 (talk) 16:06, 29 March 2018 (UTC)

GA ReassessmentEdit

This discussion is transcluded from Talk:ZX Spectrum/GA1. The edit link for this section can be used to add comments to the reassessment.

This article was promoted to GA status in 2006, which is a lifetime ago in Wikipedia terms. Since then, our standards have improved a bit. As it stands, the article fails criteria 3 for not being broad in its coverage. There is almost no information on the development of the system or the commercial success of the system. The reception section contains one single review from an American publication, while the software section does not identify any particularly notable products. The legacy section likewise fails to articulate the significant impact of the computer on the history of the British computer industry and the global video game industry. Furthermore, several topics discussed in the lead are not present in the body.

The article also fails the well-written criteria, as there are numerous one-sentence paragraphs. Finally, there are some sourcing issues, such as the use of Planet Sinclair, which appears to be a fan site without editorial oversight or a reputation for fact-checking and accuracy. While the article is certainly not terrible, it has so many issues, that I am doubtful that it can be recovered without a fairly substantial rewrite. Indrian (talk) 16:21, 29 March 2018 (UTC)

  • Revoke GA status. It might as well have a Template:More citations needed at the top. Cognissonance (talk) 11:44, 30 March 2018 (UTC)
  • Revoke as per nom. Reception & Legacy are way too short in comparison to the cultural effect and the advances in computing the Spectrum actually had. ~ P*h3i (📨) 23:10, 9 April 2018 (UTC)

Looks like we have agreement here. I am going to go ahead and delist the article. Indrian (talk) 23:18, 9 April 2018 (UTC)
