Any interest in expanding the article to cover the NEC Spinwriter ([1])? Bongomatic (talk) 14:37, 16 June 2008 (UTC)

I'd be interested to see some expanssion. Soemthing I've always wondered - where thimbles invented to dodge a patent on daisywheels, or was it for a mechanical advantage of reduced rotational inertia (from their reduced diameter). Andy Dingley (talk) 13:03, 28 August 2008 (UTC)
Hi Bongomatic, thanks for finding the necam.com material. I did check nec.com, nec.jp and necdisplay.com, google images etc without success. Can you find anything independent? Anything published by the vendor is a bit suspect in Wikipedia, for obvious reasons. I've actually held a thimble in my hand but I've no idea where I would go now to find an image of one, or an output sample. NEC was early to market with 24-pin dot matrix output which helped kill off the Spinwriter, as I recall. - Pointillist (talk) 23:56, 17 February 2009 (UTC)
Andy Dingley, I suspect the answer was "both the above". NEC was a pioneer in "clean room" Reverse engineering, saying to engineers "it has to do this, but better". The V-series 808x-alikes are a good example. - Pointillist (talk) 23:56, 17 February 2009 (UTC)
Hi Pointillist, for non-controversial information, like specifications, actually primary sources are fine under WP:V, and the citation is only intended to demonstrate the existence of the thimble configuration in the first place (I was unable to find a drawing, but if you drill down under Spinwriter there are tons of old manuals, etc).
For the comparison between daisy wheel and thimble, that looks all very subjective to me in the first place—I would be surprised if someone put a UL study looking at the printing speed at which daisy wheels versus thimbles exploded.

Thanks for the quick feedback. Well, I would prefer a third party image if I can find one or take one (I must have had hundreds of opportunities to photograph Spinwriters in the past). No, I never heard of a UL report on daisywheels "going critical", either, so I'll pull that comparison from the article. - Pointillist (talk) 00:32, 18 February 2009 (UTC)

"Graphics" section: Brother Twinriter 5 and 6 models worth mentioning?[edit]

Brother Industries manufactured the Twinriter 5 (1985) and 6 (1987) printers which tried to overcome the limitation of the missing graphics capabilities of daisy wheel printers by adding a dot matrix print head to the existing daisy wheel print head, with the former being used for letter quality printing and the latter for drafts and for printing symbols which were not present in the daisy wheel character set. Here are a few of the more relevant links I've found about these printers:

[2] (Twinriter 5)
[3] (Twinriter 6, with picture further down the page)
[4] (Twinriter 6)

These printers are worth mentioning in this section in my opinion. What do you think? Rberra (talk) 16:45, 4 December 2009 (UTC)

If you've got sourceable content, then by all means go for it. Andy Dingley (talk) 20:28, 4 December 2009 (UTC)
