Power to expansion cards?[edit]

how are expanison cards supplied with power - is this dependent on the bus architectur (do buses contain a "power line") —The preceding unsigned comment was added by (talkcontribs) 18:00, September 1, 2005 (UTC)

They must do, and presumably two or more pins are reserved for this purpose - I cannot find any information on this subject. Several PCI-E graphics cards on the market now have a molex connector as well because they use so much power.--ChrisJMoor 13:46, 26 January 2007 (UTC)
I stand corrected, the pin assignment of almost every backplane computer bus is available here (in the external links section of this article!). It is...mostly clear which pins are power supply/ground. Perhaps it should be mentioned that the physical bus connectors usually have power pins.--ChrisJMoor 14:04, 26 January 2007 (UTC)

Television set plug-in cards[edit]

I have worked on older televisions, namely RCA consoles from the 1970s, and many of them featured a motherboard-like circuit board mounted to a metal chassis, with slots for vertical, plug-in modules. The modular "cards" were single-sided boards. Some of them had molex connectors for use in connecting to other areas of the set as well. I haven't worked on one of these sets in a while but if I do I will take some pictures and propose a writeup about it. Stovetopcookies 22:00, 22 June 2007 (UTC)

History section incomplete?[edit]

Seems the history section misses to mention VAX, S/360, PDP, etc.. and other early computers that most likely proceeded the mentioned ones. Electron9 (talk) 09:11, 19 December 2009 (UTC)

Recursive Definition[edit]

The first sentence is recursively defined. It has the word as part of the definition.


The article Expansion slots has been tagged for merge for nearly a year. I suggest it would be useful to merge any unique content from that article to this, since it's difficult to talk about expansion cards without mentioning the slots they plug into. The slots article is short, fragmentary, and named in the plural which isn't customary for article titles. Any objections? --Wtshymanski (talk) 13:52, 26 October 2012 (UTC)

Interestingly enough, expansion slot (singular) has redirected here since November 2004‎. Expansion slots redirected here as well until 19 October 2011, when arguably a content fork was created. The merge suggestion tag went up less than a month later, on 13 November 2011. We also have ‎List of computer bus interfaces and Category:Motherboard expansion slot, which needs a "main article". We also have ROM cartridge and RAM pack which are just external expansion cards enclosed in cartridges—they all connect using edge connectors. I'll work on sorting it all out, I agree that content needs consolidated. – Wbm1058 (talk) 19:22, 30 October 2012 (UTC)
Then there is also Expansion bus. An expansion card fills an expansion slot on an expansion bus. It's easy to see how the same basic information could be duplicated in three places! Even more if there are "list of" busses/cards/slots articles. Wbm1058 (talk) 19:42, 30 October 2012 (UTC)
