TI-H: Turboed calc stats
I did some tests on my calc this afternoon (feeling ill
and really didn't want to face up to PoliSci). Here are the
results.
Equipment
---------
1 TI-85, with removed C9 and R11. R11 replaced with 2.67 K
resistor. C9 removed entirely, removed with switch that switches
a 33pF ceramic capacitor in and out of the circuit. Lead length
probably adds some stray capacitance.
Speed
-----
first number is turbo, second is regular mode. Most values
rounded to the nearest second.
Send backup (Connect85, parallel link, 21K file): 34s 35s
Graph y=sin x, ZStd: 4 9
Graph y=sin x, ZFit (includes fitting time): 8 16
Solve log(ln x)=1, initial guess of 1: 2 4
Solve x^2+2x+65=0, using Roger Wolfson's Quadform 6.0,
time measured from initial press of Enter to appearance
of options menu: .5 1.0
Power Consumption
-----------------
In mA, definitely not too accurate--cheap VOM. Again, turbo
is the first value.
Idling in TI-OS:4 4 (not a typo)
Graphing/Calculating in TI-OS 20 14
ZShell menu screen: 22 15
Playing Jezzball: 20 12
Displaying picture in picview: 23 14
Hope this adds some facts to all of the speculation about
turboing calcs.....
