Hello Folks,

This morning upon startup of my '89 100Q, instead of getting the reassuring
"OK" from the instrument cluster display, all I saw were four horizontal
white lines -- top two closely spaced, bottom two widely spaced.  I cut the
ignition and tried again, with the same result.

It's a cool (45F) morning, and humidity is low;  never saw this behaviour
before, neither at sub-zero temps, nor in high humidity.  Is my computer
getting dislexic. or...?

Any suggestions/war stories from others having seen this greatly appreciated,

Jos
