[edit] Renaming from Motorola to Freescale

Neier can't be bothered to figure out Freescale didn't produce a 68040, and I've apparently screwed up backing out his st00pidity.

KJS3 - Please see http://www.freescale.com/webapp/sps/site/taxonomy.jsp?nodeId=0162468rH3YTLC61654622 . The 68k, CF, i.MX, etc are all divested from Motorola with the Freescale spinoff. Neier 05:29, 1 February 2006 (UTC)

Neier - By your rationale, we should call my old 1991 Volvo 240 a Ford 240 because Ford purchased Volvo. Please stop making edits were one is neither accurate nor desirable.

No, Ford has not discontinued the Volvo brand name. Please point to me a spot on Motorola's web site where you can order the 68040, or for that matter, any device formerly produced by their Semiconductor Products Sector (now, Freescale).

Nor has Ford ever marketed it as the "Ford 240". They are content to let it remain named Volvo. Freescale markets the 68040, etc. and has no intention of leaving Motorola in their product names at all. Wikipedia should follow the companies' decisions. Neier 22:29, 1 February 2006 (UTC)

The problem is that Wikipedia isn't a brochure of currently available products, it is an encylopedia, and how things are known in a historical context is important. Whilst the CPUs are now being sold by Freescale, they were originally developed and sold by Motorola, and they are surely far more well known as "Motorola 68K CPUs" than "Freescale 68K CPUs" (eg, 36,700 Google hits for "Motorola 68040" versus 2 for "Freescale 68040"!)

Thanks Mdwh. Articulated much better than I could. But I suspect Neier won't get it. Kjs3 02:09, 2 February 2006 (UTC)

Thanks, Mdwh. The differences between a product brochure and an encyclopedia are duly noted. The MoS seems quite clear as well, at least as far as "common names" goes. This st00pid guy gets it. So, I guess it is better to focus on making the articles more up-to-date in a historical context rather than enforcing a company POV on the article names.

Kjs3, why the hostility? Mdwh's explanation makes much more sense to me than your claims that "Freescale didn't produce a 68040", "Freescale does not, and as far as I can figure never did, produce an mc68060", and "A trivial check would show Freescale never produced the 68060". In fact, it was a trivial check that showed me that Freescale does still produce the chip. A well-reasoned and researched response is better than bad analogies and blanket statements that are just false.

As for the name calling and such, if it makes you feel better, fine. Myself, I've never been cool (er, k3wl) enough to keep up with the new spelling fads. Neier 02:47, 2 February 2006 (UTC)

[edit] 3.3V Version

There was at least one 3.3V variant, which I would expect (but have not tested) to run cooler than the 5V versions. I remember this as being a 68EC040, sadly I don't think there was ever a 3.3V full 68040. Anyone have data to back up my (non-ECC ;-) memory? AndrewBall 01:55, 18 January 2007 (UTC)

[edit] 50 MHz Variants

There was a 50Mhz 68040 variant: http://www.micromac.com/products/speeddoubler040.html http://www.sonnettech.com/product/quaddoubler.html

Note that the '100/50mhz' noted in the pages refers to the internal clock of the chip, which ran at twice the speed of the external clock

Or was the 50Mhz part just an overclocked 40Mhz part?

If I recall correctly, it was the other way around - the internal clock was half the external, i.e. a "25Mhz" '040 had a 50Mhz clock input. Apple took to mentioning the external clock rate in advertising, in order to keep up appearences relative to the 486. Mirror Vax 23:45, 24 Apr 2005 (UTC)
