Core plane image
Kudos to Sanders muc for contributing the core scans. :-) Would you be able to count the lines (and number of cores) in one direction so we could calculate the memory capacity in bits & bytes for the plane shown? It would give the article even more educational value if the readers were able to immediately compare core to semiconductor RAM chips in that parameter, I think. --Wernher 16:07, 2 May 2004 (UTC)
- Ok, I counted them. Its an array of 128x128 rings, totalling to 2 KiB. Is there, BTW, a way to get a caption under an image without the "thumb" option? Sanders muc 09:31, 3 May 2004 (UTC)
- Yes, I fixed it, at least temporarily. What I'd really like, for consistency, is a captioning scheme looking just like the thumb & caption scheme but without the thumb option. However, I haven't found this yet. --Wernher 20:17, 5 May 2004 (UTC)

The caption says the distance between the cores (rings) are 1mm. Eh -- which distance, the short one between cores in a 'quad-core group', or the long one, between cores in different groups? --Wernher 02:06, 8 May 2004 (UTC)
- Well, sort of the middle between them. Its only a rough estimate. Maybe I take a magnifying glass with me to check. By the way, the quad groups don't have anything in common. It's only due to mechanical strain in the wiring. Sanders muc 11:34, 9 May 2004 (UTC)
