HP-17B notes:
  • Had functions for getting sum xy etc. based on the summation list.
  • LAST extracted number from history stack to the calculator line.
  • The calculator didn't have precedence but the solver did.
  • To start the self test, with the calculator on, press and hold the fourth menu key from the left and press the ON/CLR key. Pressing the + key will step through a series of tests (including printing a copyright) until you see KBD 01. Then you must press each key from the upper left from left to right and then down until you see KBD OK. Pressing + again displays OK-17B-E. If there is a problem, you will see a FAIL message. To exit the test, at any point, press and hold the third menu key and then press the ON/C key. Instead of stepping through the general tests, you can start some specific self tests after pressing LOG+ON/EXIT by pressing
    • 1st Menu key: SPD
    • 2nd menu key: Beep
    • 3rd menu key: DISP
    • 4th menu key: ROM
    • 5th menu key: DRAM
    • 6th menu key: URAM
    • RCL: ESD (electro-static discharge test?)
    • STO: KBD
    • %: Displays the OK message
  • A continuous test (minus the keyboard test) can be started by holding 1/x and pressing ON/C. Exit this test in the same way as the individual test.
