Wow, this little beauty is made of unobtanium, half life of youllneverseeit. The Keyboard and Mouse connect through pass-through connectors to the system.
9507 DC Plug
Peter Wendt spake:
Yes I pulled it from under the workbench and I even took it apart, which is a bit tricky due to the *security hex* (not TORX) screws. But I did it.
The DC output ratings printed on it are 12V, 1.3A / 5V, 1.4A, AC input is rated 100 - 240V, 0.6 - 0.3A, 50/60 Hz (worldwide useable).
4 pin plug of unfamiliar shape, ressembles Mini-DIN for keyboard / mouse, but with fewer but thicker pins 4 wires: red, yellow, blue and black.
Looking *into* the DC plug from the open pin side the assignment is as follows:
Red = + 5V
That blue wire is a bit estranging. There is a difference of 0.6V (monitor off) and 0.4V (monitor on) between that and GND. The power unit has two LED's: amber and green. Amber is "Power", comes on when AC is applied, green is "Activity", comes on when the monitor is connected and the system is not in power save mode.
Height: 225mm, Width: 120mm, Depth: 60mm (body), 130mm (with base). Black and weighs about 300g probably. All-plastic case with 3 catches at the front to accommodate the cable / converter box for the 9507 (that box, which detects the mouse and keyboard signals and turns on / off the screen). DC cable length: about 1 meter, non-detachable.
Hope it makes it clear. Do you want / need photos also ? Else I stuff
it back down again.
User Adjustable Effects
The two effects which are easiest to identify and adjust are Vertically and Hoizontally off-center image. Other effects are more subtle. In particular, liquid-crystal displays driven by an analog source exhibit certain optical effects which may, in some applications and workplace environments, over a period of time become distracting.
They are liable to be perceived by the user as:
However there are some colors which liquid- crystal displays cannot represent easily when driven by an analog source. The display creates these colors by switching alternate pels on and off, or half off. If you cannot get an acceptable rendering of a particular color, the user may have to choose another.
Non adjustable Effects
You cannot adjust these pinpoints or remove them. The design specification
for the IBM 9507 Color Display allows a small number of failed pixels,
comprising a mix of on-pels and off-pels.
9507 Color Display Adjustment Settings
Only attempt to fine tuning when stable temperature conditions have been established for the IBM 9507 Color Display. This will generally mean that the display panel has been running for at least 20 minutes.
Leave Switch D at 0 and Switch A at 1.
Rotary Switch B Functions
Use B2 to decrease value (-).
For each function selected
with the rotary switch B pushbuttons B2 and B3 are used to effect a shift,
in opposite directions, from the current internal settings. The shift in
settings affects the characters on the screen. One press causes a one-increment
shift in the value of setting.
