Some 10B trivia:  The 10B was introduced in January of 1989.  Many places on the internet will report that it was introduced 1987 and in fact, every 10B made between 1989 and 2000 had a copyright of 1987 on the back.  This is just the year that the rear housing of the entire Pioneer series calculators was designed.  There were 11 different Pioneer calculators and even the 32SII which was introduced in 1991 had a molded rear housing with 1987 copyright date on it.  The original color scheme of the 10B was brown with yellow key labels most people are familiar with and 1999 was the last year the 10B was made with yellow labels.  The calculator in this listing was made in 2000 (last year of production) with date code ID00405722 (4th week of 2000).  In 2000, the 10B color scheme transitioned to a teal green instead of yellow.   The 10B was discontinued shortly after that when it was replaced by the 10BII in 2001 which was known to be of poor quality in early production runs.
