Changing IC's on a NEAX 12 - what a memory! As I remember every feature had it's own EPROM. I remember when we went to 1+ dialing in NYC and put in a request to NEC for 800 chips. They gave us a 6 month lead time! What to do in the mean time? Tokyo's reply was to unrestrict every phone! Needless to say, the customers screamed.
In the end we bought a chip reader, a writer, an oven and after a little practice, 1,000 blank chips and got the customers up and running. I think we violated the warranty on 800+ systems, but we got the customers up and running.
