Removal of mostly IBM-relevant paragraphs

Just for the record: I removed two paragraphs of text which went on about IBMs later mainframe offerings and plans; if someone wants to use that material for covering IBM, please grab the stuff from the previous version of this article (via the history tab). --Wernher 21:47, 3 Dec 2004 (UTC)

PLEASE use the original Amdahl logo. The Fujitsu-ized logo is widely despised. I can provide it to you if necessary. redducatist2 (at) hotmail —Preceding unsigned comment added by 64.160.42.130 (talk • contribs) 03:11, 20 November 2006

I've added the original logo to the "Company origins" section. Terry Carroll 19:51, 26 August 2007 (UTC) (Senior Computer Architect, Amdahl Corp. 1991-94)[reply]

Also, you might want to mention Platform Solutions (http://www.platform-solutions.com/) where the core Amdahl engineers are now working on a new plug-compatible product. —Preceding unsigned comment added by 64.160.42.130 (talk • contribs) 03:29, 20 November 2006

Nomenclature

The original design, announce as the 470, was dropped and as far as I know it was never shipped. It was replaced by the 470V line, with the first model being the 470V/6. I have seen no Amdahl manuals referring to it as 470V6, 470/V6, 470 V6 or the like. Shmuel (Seymour J.) Metz Username:Chatul (talk) 00:28, 6 September 2010 (UTC)[reply]

Was the console notable?

At the time that the 470V/6 was current, Amdahl was quite proud of it's use of a Data General Nova 1200 as a console processor, although the large motherboard had reliability problems because it sagged. Was that console processor notable enough to justify including in the article? Shmuel (Seymour J.) Metz Username:Chatul (talk) 00:41, 6 September 2010 (UTC)[reply]

31-bit addressing

For the last several years, this article documented that the architectures supported by the XA and later Amdahl systems used 31-bit addressing. Last weekend, in a series of edits by an anonymous editor ([1], [2], [3]). This was "corrected" to 32-bit. I think this was a good-faith edit, but the editor was unfamiliar with the architecture and 31-bit addressing, and assumed it was an error for the more familiar 32-bit scheme. I undid those changes, restored it back to the correct 31-bit ([4]). My undo, was itself undone with the comment Data are still 32 bits ([5]). I'm just documenting this here to avoid an edit war as I restore it to the status quo. This was 31-bit, not 32-bit. For an example of a discussion of this, see, e.g., the IBM pub at [6]. If there is still any belief that this should be called 32-bit, please discuss here and reach a consensus before changing it from the longstanding article content. TJRC (talk) 05:19, 8 September 2010 (UTC)[reply]

That is an incorrect description of my edit; I did not change 32-bit addressing to 32-bit addressing. What I changed were 31-bit mainframes and 31-bit support, neither of which refer to addressing. Current IBM mainframes in the IBM System/360 line have 64-bit registers as opposed to 32-bit, and *that* is what Amdahl is not supporting. Please don't confuse a select edit with a reversion and don't confuse me with the poster at [212.152.181.180 ]. Shmuel (Seymour J.) Metz Username:Chatul (talk) 12:36, 8 September 2010 (UTC)[reply]

There is no 470/5

There is no 470/5, only a 470/6, 470V/5, 470V/6, ... I assume that the image is a console for the 4705, a replacement for the IBM 3705. Shmuel (Seymour J.) Metz Username:Chatul (talk) 22:59, 22 May 2012 (UTC)[reply]

It's clearly a 4705. The accompanying text makes no sense, either:

Amdahl Corp. launched its first product, the Amdahl 470/6, in 1975, competing directly against IBM's high-end machines in the then-current System/370 family, but with IBM's announcement of Dynamic Address Translation (DAT), Amdahl announced the 470V/6 and dropped the 470/5.

I only had a few seconds in the warehouse to snap a few photographs, without any context, so I had to make some guesses as to what they were. Nearby was this Amdahl control panel, but I don't have any details on it, either. -- Autopilot (talk) 01:44, 24 May 2012 (UTC)[reply]

Regardless, thanks for the photo. Photo contributions are more scarce than text, so it's very much appreciated. TJRC (talk) 15:32, 27 May 2012 (UTC)[reply]

Anachronism

Amdahl Corporation claims

Amdahl launched its first product in 1975, the Amdahl 470/6, which competed directly against high-end models in IBM's then-current System/370 family. When IBM announced the introduction of Dynamic Address Translation (DAT), Amdahl announced the 470V/6 and dropped the 470/6.

However, DAT was announced in 1972. Shmuel (Seymour J.) Metz Username:Chatul (talk) 20:10, 3 April 2018 (UTC)[reply]

Logo

What is the best logo to include in the infobox? It seems that Fujitsu does not really market the current logo that is stated there, so maybe the old version is the better option. PhotographyEdits (talk) 08:25, 10 June 2024 (UTC)[reply]
