Hardware Description
An algebraic scientific/statistics calculator. This model didn't have a four level history stack but still made the previous result available via the LAST key and a SWAP key allowed the numbers surrounding an operator to be reversed. (eg 5/25 SWAP yielded 25/5.) The calculator had a single line dot matrix display that could display either a menu or a number.
