I just received a call from Steve Starr of the Appleton Medical Center in Appleton WI. They desperately need to replace a chip in their Canberra 30 MCA. The chip is no longer commercially available. If you have a 30 that you have retired to pasture or a dead one that can be cannibalized please call him at (414) 831 5063. Thanks Paul Frame framep@orau.gov
