Talk:Expansion card

From Wikipedia, the free encyclopedia

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 83.64.80.66 (talk • contribs) 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)

[edit] Televisions

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)
