Question about the F-22 and it's radar.

Just the official reports!!, Lockheed has only purchased enough
processors for 155 F-22's because there out of production, the demand
for Air to ground operations has increased the demand on processing
power, something the original processors are not quite upto hence the
_need_ for the 'upgrade'.

I kind of find that hard to believe. The system I worked on (and is still a
front line system) was based on Z-80's and a bunch of other 'exotic' chips.
If they can still find parts for that, the F-22's radar should be too
'obselete'.
