They have socketed chips with extras on each board. In about 10 Megabyte-years I've had to swap maybe 3 chips (there is a whole book on how to do it). The memory is not on service since the cost of service for the warantee period (2 years) would buy a new board. Furthermore changing chips is about the only service I imagine will ever be needed and I do that fine. So consider the service cost "free". (they promise 24 turn-around on boards returned under warantee.) Other managers whom I asked before buying this stuff all had found a different supplier (about 5 vendors were mentioned) and all were happy. Some have warantee periods of 5 years. It looks like memory is one area where youcan't go far wrong. By the way, another site at Columbia just did a 4 Meg/old controller for 8 Meg /new controller deal with EMC and they are happy with cost and performance. Local DEC will service them also (DEC Field service largesse extends at least from NYU to Columbia). (If I were they, I would put the controller on contract and the memory off contract as per above price vs. warantee comparison). Rg PS -- How about a survey on the wonderful world of microVAX-II memory prices. Now that's an exciting market (for users, pity the vendors). Rg -------
