Enter your name:

1. What key do you press before entering a new program?

STO PGM LRN R/S RST

2. TI-59 did calculations with how many accurate (well, most of the times) digits?

8 9 10 12 13

3. What does the EE INV EE sequence do?

Remove the exponent from a number Remove the mantissa from a number, leaving just the exponent Remove decimal digits not displayed on the screen Remove the sign from the exponent Nothing

4. Top file keys were marked with A, B, C, D, and E. What is written above them?

Nothing a, b, c, d, e A', B', C', D', E' 2nd A, 2nd B, 2nd C, 2nd D, 2nd E, Short horizontal lines

5. What sequence was used to test the correct functioning of the calculator?

2nd Op 00 2nd Op 99 2nd Pgm 00 A 2nd Pgm 00 SBR = RST R/S

6. What was written in the lower right corner of the calculator, under the TI Programmable 59 line?

Solid State Software Scientific Calculator Electronic Calculator Copyright (C) Texas Instruments, Inc Nothing was written there

7. While editing the program, you press 2nd Ins. What happens?

A 00 code is inserted before the current command A Nop (68) code is inserted before the current command A 00 code is inserted after the current command A Nop (68) code is inserted after the current command A code stored in t register is inserted before the current command

8. What does 2nd Op 10 do?

Increment register 0 Increment register 10 Calculate coefficient of correlation Download library program to the main memory Calculate signum

9. 2 + 3 x (4 + 5 = gives:

29 29 blinking (because the parentheses were not closed) 45 45 blinking (because the parentheses were not closed) 0 blinking (error)

10. Code 42 represents instruction...

EE STO RCL x<<>>t x2

11. In order to calculate arcus sine, you press:

2nd sin INV sin INV 2nd sin Arc sin Arc 2nd sin

12. Press 1 +/- 2nd Write to:

Save data register 0-29 on the magnetic card Save data register 0-29 on the magnetic card, as a protected data bank Save program steps 0-239 on the magnetic card Save program steps 0-239 on the magnetic card, as a protected program Read program steps 0-239 from the magnetic card

13. What game was included in the Master Library module?

Lunar landing Jive turkey Mastermind High/low Nim

14. 2nd Pgm 15 SBR D.MS was often use to:

Transform polar coordinates to rectangular Convert Degrees, Minutes and Seconds to decimal numbers Convert decimal numbers to Degrees, Minutes and Seconds Convert hexadecimal number to decimal system Generate random numbers

15. HIR 2x codes:

Store numbers in internal registers Recall numbers from internal registers Add numbers to internal registers Print contents of internal registers Nobody ever found out for sure

16. How many flags TI-59 has?

9 10 60 99 100

17. What is the number of the last data register, in 10 OP 17 partition?

10 59 60 99 100

18. You want to save memories 00 through 10. Which is the correct procedure?

Enter 0, press 2nd Write (and insert card) Enter 1, press 2nd Write (and insert card) Enter 2, press 2nd Write (and insert card) Enter 3, press 2nd Write (and insert card) Enter 4, press 2nd Write (and insert card)

19. What is the difference between A and GTO A in the running program

A is a label address; GTO A is an absolute address A defines the label; GTO jumps to the label A is a subroutine call; GTO A is an unconditional jump A is an indirect jump to the address stored in register A; GTO A jumps to a label There is no difference

20. You enter 1 and pass the magnetic card. The display is flashing 3. What is the problem?

No problem, but you need to pass three more cards in order to load the complete program The card reader's mechanism needs cleaning You did not press INV 2nd Write Partitioning should be 3 Op 17 Bank 3 is recorded on the magnetic card, and you tried to load bank 1
