As an aside, a version of the 1802 was the main processor on the Galileo space probe, which recently ended its mission by being crashed into Jupiter. (There's a nice, general article about Galileo in the September 8 issue of "The New Yorker" magazine, starting on p. 38.) -----Original Message----- From: Brian Herbert [mailto:bkherbert@adelphia.net] Sent: Thursday, September 25, 2003 8:03 PM To: cctech(a)classiccmp.org Subject: RCA Appnotes Dear Bob; I am puting together a history of low power systems and came across the RCA 1802 as maybe the earliest single chip CMOS processor (along with Intersil 6100). I am trying to figure out when the RCA ICAN-7029 appnote was written and wonder if it is in your Microsystems Manual or if you have other databooks.Thank you. Best Regards, Brian
