Not in that line, the 16C was it. The 15C was the engineering model. What the world 'needs' is a 15C/16C hybrid, built in the old style. Maybe without the matrix functions or something. I have a place in my heart/life for a good _calculator_, if the going gets heavy I'm going to reach for a computer anyway. > I always thought of the 12C as the gold trimmed brain damaged > sibling of my 11C, but it seemed to be in the stores long after > the 15C was discontinued. It was. The 12C holds the record for the longest-lived production consumer electronics device, period. Made essentially unchanged since 1981, and perhaps still in production. I understand that this is partly because it is one of the few certified-for-MBA calculators you can buy. (That is, its financial algorithms are 'blessed'.) http://www.hpmuseum.org/hp12c.htm -- Jim _______________________________________ http://www.okiebenz.com For new parts see official list sponsor: http://www.buymbparts.com/ For used parts email [EMAIL PROTECTED] To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
