Note about the use of template for the text here
I've been a bit unconventional about using Template:Keydrive internals to store the descriptive text for this image, but I think I have good reason. There needs to be a caption, plainly, on the article in which this image is used (otherwise the numbers on the diagram are just annoying). But the caption needs to be on the image page too, as that's what someone will see when they click on the image, and they should be able to figure out what the numbered bits and bobs are without having to flip back and forward been the big image page and the page in which the image is displayed (as a thumbnail). To make this easy, and to ensure there's no divergence, I used a template as a caption. Naturally the template needs to contain text that makes sense both in the actual wikipedia page and also on the image page (so that's why the title isn't in the template, and why the image licencing info isn't either). -- John Fader
 * I see your point about using the template for layout. It's not that appropriate for a caption, however, on the Keydrive page.  It's too long.  Would you be interested in making something like an info-box you see for presidents and airplanes for the numbered items, and integrating the other information into the main article?  I think that would lead to a clearer, more understandable article rather than two semi-articles side-by-side.  --ABQCat 23:47, 4 Dec 2004 (UTC)

Can they do chin-ups too?
What does it mean that the resistors serve as pull-ups? Does it have anything to do with pull-up and pull-down transistors? &mdash; Brim 08:23, Feb 5, 2005 (UTC)


 * It means they are pull-up resistors. A pull up resistor means that the value of the pin is logic-high unless a current is actively asserted on that pin.  Without a load (either active circuitry or pull-up or pull-down resistors) the voltage on a pin will float freely, and the logic value will change spontaneously.  Pull up resistors are typically pretty high values (1000 ohms or more) so it won't be very difficult for an ordinary active signal to overcome the drain they represent.  It's really not related to a pull-up transistor. -- John Fader 18:04, 5 Feb 2005 (UTC)
 * Thank you for your reply. I wasn't able to find anything about pull-up resistors or pull-up anything in Wikipedia, that's why I asked.  Would you be able to write a small section under resistor (or another appropriate article) about this topic? &mdash; Brim 00:00, Feb 6, 2005 (UTC)
 * Yes, you raise an excellent point. My reasons for adding this (rather excessive, perhaps) exploration of the components on the keydrive was to serve as an introduction to numerous digital electronics topics.  It doesn't make much sense when important topics, like pull-ups, don't have articles. I'll add writing something about pull-ups and downs to my to-do list. -- John Fader 17:33, 16 Feb 2005 (UTC)
 * Thanks. I think that will be a great contribution to Wikipedia.  I'll be looking forward to your article. &mdash; Brim 04:28, Feb 17, 2005 (UTC)
 * I also wondered what a pull-up was, and there has been a pull-up resistor article writen since the above comments, so I've linked to it within the caption. &mdash;Pengo 23:46, 18 February 2006 (UTC)
