Personal diagnostic cart
of Pete Gerard |
Pete's Test Cart was a special test cartridge created by 5200 hardware
engineer Pete Gerard. Pete's Test Cart helps test and calibrate
the 5200's controllers and test the color registers. It is unknown
if Pete made this test cart for himslef or distributed it to other employees.
It is believed that this test cart predates the regular 5200 Disagnostic
cart.
Pete's Test Cart contains four different tests which
are selected by pushing the top and bottom fire buttons.
Joystick Calibration
The first test is a joystick claibration screen. A
small dot is displayed in a blue box and can be moved to the various corners
of the screen. The dot's color can be changed by pressing the 0-9
keys. Pressing the bottom fire button will bring up the Pokey Adjust
screen.
Pokey Adjust
The is the same Pokey Adjust screen that is in the 5200
Diagnostic Cart. By moving the joystick around the horizontal and
Vertical pot values will change. The KB displays the current key
that has been pressed. Pressing the top joystick button will display
the word "Calibrate" which indicates that Trak-Ball calibration
has been turned on.
Gray Bar Test
This is the standard gray bar test that is found in
the Diagnostic cart. It was used to test the clarity and brightness
of the various shades of gray the 5200 could produce. This test
is accessed by pressing the top fire button from the calibration screen.
Color Bar Test
Much like the Gray Bar Test, this test was used to test
the 5200's color capabilities. It is accessed by pressing the top
fire button from Gray Bar Test screen.
