IMPSYS Change Notification

        We will shortly install (or perhaps will have already
   installed) a new version of the IMP system, Version 2513.  The
   new version incorporates two principal changes:
  1. A Host will be prevented from sending any messages into the Network for between 40 seconds and a minute and a quarter after he comes alive (this has been changed from between 30 seconds and a minute).
  1. The IMP has been given the ability to test its Host interfaces under control of the NCC. This will help us isolate the trouble when the IMP Host communication path is faulty.
