Has the HP12C improved in chip speed over the years? Message #1 Posted by dave brown on 23 Sept 2003, 2:16 p.m. My finance prof said this in class but I wonder if it's really true? Is an HP12C bought today faster than 1 made, say, 15 years ago? (This would be reason to buy newer ones) Thx if u know

Message #2 Posted by David Ramsey on 23 Sept 2003, 5:43 p.m., in response to message #1 by dave brown No. A 12C bought today is no faster than the very first one off the production line. Now, the 12C Platinum, a new version, uses a different processor and is faster for most things. However, a number of bugs have been discovered in the Platinum version and most HP fanatics prefer the original.

So they slowed it back down. This could be legend, though. -Joshua Belsky

Message #5 Posted by dbrunell on 24 Sept 2003, 12:16 a.m., in response to message #1 by dave brown Can anyone tell me when they switched the 12C from double-shot molded keys to painted-on legends? I have in front of me a 1995 Singapore model with painted keys.

Also, for some strange reason, HP would paint over double-injection molded keys. See http://www.hpmuseum.org/collect.htm#variations and scroll down to "10C Series Versions."
