Claiming this review; I'll start posting comments soon. --PresN 23:38, 25 January 2024 (UTC)[reply]

Thank you for taking the Herculean task of reviewing the mighty Spectrum, PresN! I have returned in good time, and will begin addressing your comments. I note that some of the technical sections have been altered or degraded since I have been gone - but will tackle that when we come to it. ♦ JAGUAR  22:52, 4 February 2024 (UTC)[reply]
Lead
  • I've removed the mention of clones entirely and condensed the rest. I think it reads alright. ♦ JAGUAR  23:19, 4 February 2024 (UTC)[reply]
  • Inclined to agree, though I think most know British English employs a more colloquial reading experience, even for Wikipedia. I've changed it to 'creation'. ♦ JAGUAR  23:19, 4 February 2024 (UTC)[reply]
  • Yeah, that would be a nightmare. Changed to 'EU'. ♦ JAGUAR  23:19, 4 February 2024 (UTC)[reply]
In 1985 Spain wasn't in the then EC (the EU didn't exist under that name in 1985 either). Although I can't quickly find a single source which lists release dates in different European countries, I would have expected that it was launched earlier in e.g.
Ireland than Spain. 90.167.254.202 (talk) 22:29, 29 March 2024 (UTC)[reply]
'EU' is generally referring to Europe; it is easier to cluster the releases that way. ♦ JAGUAR  21:56, 2 April 2024 (UTC)[reply]
  • Agree. Since I removed the mention of clones above I hope it negates this issue. I'd call the Timex versions versions, and the Soviet imitations clones. Let me know how it reads? ♦ JAGUAR  23:19, 4 February 2024 (UTC)[reply]
  • Happier with the lede now! --PresN 03:27, 5 February 2024 (UTC)[reply]
Background/Development
  • I've cut down on some of the less relevant company history. I took inspiration from the ZX81's background subsection, which to be fair adheres much less to WPVG's manual of style. I think keeping the mention about Sinclair's relationship with the NEB is important, as his breakup prompted him to develop microchips, which ultimately led to the Spectrum. ♦ JAGUAR  11:51, 13 February 2024 (UTC)[reply]
Hello, Jaguar, and thank you for your interest in the article.
I didn't see this review on time, so I reverted your edit [1]. If you really feel that it doesn't belong to the article, then you can undo my revert. However, I personally find the remove sentence both interesting and relevant. Z80Spectrum (talk) 16:00, 25 February 2024 (UTC)[reply]
  • That doesn't read well! I cut the second half entirely. ♦ JAGUAR  11:57, 13 February 2024 (UTC)[reply]
  • Rephrased. ♦ JAGUAR  12:18, 13 February 2024 (UTC)[reply]
The bigger problem with that sentence is that it might be misleading, not factual. Spectrum is a very different machine than ZX81. Reused was the idea to use Z80 CPU, to use a Ferranti ULA, to output a TV signal, bitmapped graphics, a big chunk of code for BASIC.
However, those are just some generalistic issues. Nothing specific in the architecture was reused on Spectrum. Z80Spectrum (talk) 16:14, 25 February 2024 (UTC)[reply]
  • Changed to 'idea'. I'm afraid I don't know what it means, I will change it once I find out. ♦ JAGUAR  12:18, 13 February 2024 (UTC)[reply]
I can guess what it means. It was probably a part of the Spectrum's design goals to consider using only one bank of RAM. The Spectrum 16K actually uses only one bank (4116 DRAM), and the access to this bank is multiplexed (both CPU and video). Spectrum can store everything in this bank: video, audio, code, etc...
However, the 48K model has a second bank of RAM (and this bank is expensive, 8 chips of 4532, which is a half-malfunctioning 4164 DRAM, where 4164 is a more modern and more expensive tech than 4116).
So, the end design only partially follows the idea of a single bank of RAM, but it can certanly be claimed that the design goal of a product with a single bank of RAM was achieved, in the form of Spectrum 16K. Z80Spectrum (talk) 16:25, 25 February 2024 (UTC)[reply]
I have attempted to quickly dig out the DRAM chip prices, just to show the bill of materials.

(Edit: I quoted prices from wrong years (1981 instead of 1982); corrected)

4116 - (16 Kib per chip) - the price fell sharply in 1981, and then leveled off. In 1982, the price was about 0.91 USD/KiB (150 ns)
4164 - (64 Kib per chip) - the price was about 1.1 USD/KiB in 1982 (150 ns). The price was going to drop significantly in the middle of 1983, which contributed to the decrease of Spectrum's price.
4532 - (32 Kib per chip) - the price per chip was from 10% to 30% less than 4164 DRAM (which has double capacity). However, these are salvaged 4164 chips, so Sinclair could probably had made some good bargains.
The DRAM chips make about 30% of the ZX Spectrum's bill of materials (well, depending on the year). Z80Spectrum (talk) 17:58, 25 February 2024 (UTC)[reply]
I would estimate the ZX Spectrum's bill of materials at around 125 USD in January 1983 (without assembly, packaging and Q&A costs). However, this is original research. I know approximately the price of each component (individual chips), if anyone is interested. Z80Spectrum (talk) 18:13, 25 February 2024 (UTC)[reply]
  • Vickers wrote the ROM firmware, so clarified. Let me know if this still doesn't make sense? ♦ JAGUAR  21:52, 17 March 2024 (UTC)[reply]
  • I've shifted the 'ZX81 with colour' sentence to the middle so flow is improved. ♦ JAGUAR  22:56, 17 March 2024 (UTC)[reply]
As far as I understand it, the sentence is still wrong. The sentence claims that ZX Spectrum was "ZX81 with colour", which is terribly wrong. If the sentence indicated this claim as an opinion of the marketing manager, it would be much less wrong, but still misleading. Z80Spectrum (talk) 23:20, 18 March 2024 (UTC)[reply]
Aldo, that entire paragraph is quite badly written, confusing and inaccurate. Unfortunately, I don't have spare time at this moment to fix it, maybe some other day. Z80Spectrum (talk) 23:43, 18 March 2024 (UTC)[reply]
  • Changed. ♦ JAGUAR  12:18, 13 February 2024 (UTC)[reply]
Point 1. Jaguar wrote: Much of the code was written by - I think that you have nailed the problem there: the article is missing an entire section describing how the Spctrum was operated in practice. I think that some sections from the article on ZX81 can be reused for this purpose. However, this will further expand the article, so I propose splitting the history section into another article.
Point 2. Jaguar wrote the ZX Spectrum was, as quoted by Sinclair's marketing manager, essentially a "ZX81 with colour - the problem here is the following: from a perspective of initial concept of ZX Spectrum, it was a "ZX81 with color". That's what Clive Sinclair wanted, and that has been cited everywhere. However, the end-design, by engineer Altwasser, is much more than that. Alwasser has obviously put a lot of sweat into the design, even whan working under the extreme time pressure that was obviously imposed by Clive Sinclair. To cut it short, the end design is much more than just "ZX81 with color", and in that sense the sentence is misleading. Z80Spectrum (talk) 16:41, 25 February 2024 (UTC)[reply]
Point 3. Jaguar wrote The paragraph that starts with "A divergence of perspectives between Nine Tiles - the development of the firmware ended when the ROM was full, and development time had also 'run out'. It was essentially the BASIC from ZX81, plus floating point math (demanded by Clive Sinclair), additional graphics routines and a few extras (new cassete tape routines). I don't know how should that be interpreted in the article as somebody's 'win'. Perhaps it's more towards Sinclair's viewpoint. Z80Spectrum (talk) 16:53, 25 February 2024 (UTC)[reply]
  • Simplified is better, changed. ♦ JAGUAR  12:26, 13 February 2024 (UTC)[reply]
  • I'm a Luddite, me no code... still, I'm glad one of us knows what I've written about! To make things hopefully clearer, I've linked instruction cycles and inserted some plain English to make the jargon easier to understand. ♦ JAGUAR  14:59, 26 March 2024 (UTC)[reply]
  • I've rephrased and rearranged parts of the Timex paragraph to make it chronologically clearer. ♦ JAGUAR  23:25, 2 April 2024 (UTC)[reply]
Launch
  • Good question. I have determined from the Adamson and Kennedy source that the former is correct, as Sinclair started producing more units with a streamlined, cheaper motherboard. As such I've rephrased this to clarify. Also linked motherboard. ♦ JAGUAR  23:25, 2 April 2024 (UTC)[reply]
  • The source doesn't specify if the Issue 3 motherboard itself boosted sales, but I've rephrased it to separate. ♦ JAGUAR  23:25, 2 April 2024 (UTC)[reply]
  • Oops, doesn't make sense to me upon reading it again. I've removed the "a further 500k" sentence to cut confusion. ♦ JAGUAR  11:38, 3 April 2024 (UTC)[reply]
  • This seems to have been removed by another editor while I've been gone. ♦ JAGUAR  21:48, 23 April 2024 (UTC)[reply]
  • I have summarised the Timex's limited success in a not-so-meaty paragraph. ♦ JAGUAR  22:27, 15 April 2024 (UTC)[reply]
Success and market domination
  • Yes, clarified. The dominance of microcomputers was unequivocal, especially outside the US and Japan. ♦ JAGUAR  21:48, 23 April 2024 (UTC)[reply]
  • Alternately, you could just drop the microcomputer bit entirely and just say that the crash of 83 only affected America and not the UK (it didn't much affect Japan either- the main cause of the crash was oversaturation of supply in US retailers by publishers aka Warner due to a misreading of increased store demand (due to an increase of retailers carrying video games) with increased consumer demand (in turn due to nonsensical supply chains causing a complete lack of clarity of what was going on), but that only happened in the US).
  • While I agree the crash of '83 was primarily a 'US thing', it did send ripples through the video game market worldwide. There was a short-lived console market in the UK between 1980-82 which the crash may or may not have killed off. I'd prefer its inclusion, but I have tweaked it to make it clear it affected American markets. ♦ JAGUAR  21:48, 23 April 2024 (UTC)[reply]
Later years and company decline
I appologize for previously attributing Jaguar instead of PresN, sorry.
Point 4. PresN wrote With the arrival of the more inexpensive Issue 2 motherboard, production rapidly increased - 'Issue 2' is the version of the motherboard. There were multiple revisions of the motherboard, because ZX Soectrum was initially full of hardware bugs. That means many Spectrums were malfunctioning when tested brand new out from the factory line. New motherboard issues fixed those problems. It also makes the production cheaper, by not creating a huge pile of malfunctioning products. Z80Spectrum (talk) 17:05, 25 February 2024 (UTC)[reply]
  • Did this myself

I'm going to take a break here, and pick back up with the rest of the article later. --PresN 21:55, 26 January 2024 (UTC)[reply]

@Jaguar: Are you going to be able to work on this article? --PresN 23:31, 3 February 2024 (UTC)[reply]
@PresN: I can take over this review if he's gone AWOL. DigitalIceAge (talk) 00:48, 11 February 2024 (UTC)[reply]
He last edited this article a few days ago and I've been talking to him on Discord about it. --PresN 01:27, 11 February 2024 (UTC)[reply]
Thumbs up icon DigitalIceAge (talk) 01:58, 11 February 2024 (UTC)[reply]
I won't be editing the article (for the time being), but if anyone needs my suggestions, or advices, feel free to ask. Z80Spectrum (talk) 17:09, 25 February 2024 (UTC)[reply]

@Jaguar: Poke. --PresN 01:41, 23 February 2024 (UTC)[reply]

You have the patience of a saint, PresN! I have returned from abroad and am addressing your comments now. Let's hit this phase on the head. ♦ JAGUAR  21:54, 15 March 2024 (UTC)[reply]

Okay, this long-running review has gotten a bit messy. I've gone through and made tweaks to the sections above, so we're on to "Hardware" and below. --PresN 01:14, 24 April 2024 (UTC)[reply]

Hardware
  • Thanks, done. ♦ JAGUAR  17:00, 1 May 2024 (UTC)[reply]
  • True, perhaps I was trying to impress myself. Removed. ♦ JAGUAR  17:00, 1 May 2024 (UTC)[reply]
  • I agree, though I've cut down some cruft. ♦ JAGUAR  17:00, 1 May 2024 (UTC)[reply]
Sinclair Research models
  • Changed to "from Issue 2 or 3 models", since it's already addressed earlier. ♦ JAGUAR  17:36, 1 May 2024 (UTC)[reply]
  • Removed paragraph. ♦ JAGUAR  17:36, 1 May 2024 (UTC)[reply]
  • And me. Removed! ♦ JAGUAR  17:36, 1 May 2024 (UTC)[reply]
  • It was actually unveiled in Spain first. Rephrased this to clarify. ♦ JAGUAR  17:36, 1 May 2024 (UTC)[reply]
  • Much better, should have caught this. ♦ JAGUAR  17:36, 1 May 2024 (UTC)[reply]
Amstrad models
  • I admit to have given the least amount of attention to this section. I chose to remove this sentence rather than insert it elsewhere because the source's credibility was dubious. ♦ JAGUAR  17:36, 1 May 2024 (UTC)[reply]
  • It went downhill when Amstrad acquired Sinclair in my opinion, the machines themselves look dull and uninspiring, nothing like the iconic Spectrum. I don't know much about the Amstrad era admittedly. It may surprise you that they even produced a video game console, sadly crap and confined to the dustbin of history. ♦ JAGUAR  17:36, 1 May 2024 (UTC)[reply]
  • I agree. I was tempted to condense all three subsections into one (and possibly for the Sinclair models too), but that's a discussion for another day. Cut down on some cruft anyway. ♦ JAGUAR  17:36, 1 May 2024 (UTC)[reply]
Clones and re-creations
  • Reorganised and sourced. ♦ JAGUAR  23:11, 5 May 2024 (UTC)[reply]
  • I have renamed the entire section to 'Licences and re-creations', if we were to consider the licences to be official models in their own right. I'm not sure I could get away with putting the official licences in its own section without bloating the article too much. What do you think? Regardless, I have tidied the entire section, added more details and better quality refs. ♦ JAGUAR  22:30, 15 May 2024 (UTC)[reply]
  • Taken care of. Also surprised to discover what an interesting machine the SAM Coupe is - many consider it to be the 'true' successor to the ZX Spectrum. So much I considered inserting it as a 'spiritual successor' in the infobox. Anyway, expanded on that. ♦ JAGUAR  22:30, 15 May 2024 (UTC)[reply]
  • Condensed somewhat to four paragraphs. I agree, and will revaluate this for a future FAC. ♦ JAGUAR  22:30, 15 May 2024 (UTC)[reply]
Peripherals
  • Added a couple - delving into obscurity takes a lot of time! ♦ JAGUAR  23:00, 15 May 2024 (UTC)[reply]
  • Uh, deleted.. ♦ JAGUAR  23:00, 15 May 2024 (UTC)[reply]
  • I have removed this claim since I cannot verify; however I've sourced the rest of the paragraph and cut some gibberish. ♦ JAGUAR  23:09, 15 May 2024 (UTC)[reply]
Software
Reception
  • The Mega Drive is an 80s console? Jesus! I will get to fleshing out this section - will take me an hour or two to shift through some old magazines. ♦ JAGUAR  23:14, 15 May 2024 (UTC)[reply]
Yeah, it's the opposite end of the 80s, if only technically; I just didn't have better comparison points. --PresN 00:31, 16 May 2024 (UTC)[reply]
Squeezed some more content, though it's perplexing how many magazines didn't review the Spectrum until months after its release. Sinclair was notoriously late in delivering its machines indeed, unless it was the war's fault? ♦ JAGUAR  10:55, 18 May 2024 (UTC)[reply]
Legacy
  • Rephrased and combed the first paragraph somewhat. Don't want to make it sound like the ZX Spectrum was definitively the most influential computer of them all. Most explosive in the 80s, perhaps. ♦ JAGUAR  21:56, 20 May 2024 (UTC)[reply]
  • Oh, didn't see that was added recently. I hate to remove things, but I don't see its notability so have axed the sentence. ♦ JAGUAR  23:18, 15 May 2024 (UTC)[reply]
References
  • Formatting:
  • WP:ALLCAPS in refs 9, 109, 141, 142, 147, 156, 164, 176
  • ISBNs weren't consistent, so I just fixed them
  • Thank you. ♦ JAGUAR  21:13, 20 May 2024 (UTC)[reply]
  • Lack of archives and dead links abound; I ran the archive bot on it, but it crashed because some link is on the spam blacklist- I'll try to track down what.
Oh, it's kickstarter. Replaced and re-ran, but some things are still marked "[permanent dead link]".
  • "Microcomputers: No room at the inn" is a deadlink in sources but it's a google books link so it should be fixed or removed
  • That's unlike Google. The whole scan was available on there not long ago. Removed. ♦ JAGUAR  21:13, 20 May 2024 (UTC)[reply]
  • 142, 143, 147 missing source (and have it in the title instead); 232 missing source altogether
  • All fixed. ♦ JAGUAR  21:28, 20 May 2024 (UTC)[reply]
  • 70 is in references but looks like it should be in sources?
  • "The precarious balance between research, fashion and price" is in sources but looks like it should be in references?
  • Already in there? ♦ JAGUAR  21:28, 20 May 2024 (UTC)[reply]
  • 209 has CRASH unlinked and formatted differently than other refs
  • Re-formatted and moved to sources. ♦ JAGUAR  21:40, 20 May 2024 (UTC)[reply]
  • There's actually a bunch of petty inconsistencies in formatting like magazines sometimes unlinked, access dates sometimes missing, things in sources that have page numbers instead of just the work and letting the reference pointer have the page number, etc.; it doesn't really matter for GA, but someone will care for FAC if you go there. --PresN 00:46, 16 May 2024 (UTC)[reply]
  • Don't mean to sound lazy but I will make them all consistent in the event of FAC! ♦ JAGUAR  21:28, 20 May 2024 (UTC)[reply]
  • Spotchecks:
  • Spotchecks were clean, but there are a lot of refs so I could have missed something.
  • ref 102 is to a wiki
  • refs 30, 175 link to an archive page, not the original
PresN 00:51, 16 May 2024 (UTC)[reply]

@PresN: while I am burned out, this GAN has given me Stockholm Syndrome since I can't believe it's the end! Is it the end? I have addressed all your comments now. I deleted the 'community' subsection since it mainly consisted of repetitive factoids, and I didn't feel inclined to source it. I moved one of its sentences to the legacy section, and cleaned it up somewhat. Standardising all the refs will take time, but like you say it's not an actual requirement for GA and will certainly be done if (more likely when) I take this to FAC. This has been a monumental project for me, among the most challenging articles I've written for Wikipedia. I sincerely thank you for your patience over the months and keenly await your response, if you think it's ready. ♦ JAGUAR  22:05, 20 May 2024 (UTC)[reply]

I think it's the end! It's certainly a monumental project, and a long-running GAN, and of course any FAC will find more things to complain about, but for now it's over. I'm happy to promote! Congratulations! --PresN 22:09, 20 May 2024 (UTC)[reply]
