 The last contact I had was a small manufacturing company here on LI, but
 that dried up about 8 years ago. 
No, now may be the time to do the leg work and collect the tools. I am
sure that core memory can be repaired but it needs to be done under a
microscope with fine tools.
People who use core memory, I don't think have a the knowlage of where
or how to find replacement parts since most core memory is chopped up
for sale on ebay. :(  Does anybody have a stockpile of cores and driver
transitors and driver IC's.
