+RFC # 447                                               BBN-NET
+NIC # 14104                                             January 29, 1973
+Updates: 434
+
+
+             IMP/TIP Memory Retrofit Schedule (Revision 1)
+
+
+This revision contains two major changes to RFC #434.  First, all
+retrofits scheduled prior to February first have been completed and are
+therefore removed from the schedule.  Second, the CCA retrofit has been
+rescheduled from 3/20 to 2/28.
+
+The revised text of RFC # 434 follows:
+
+During the first several month of 1973 we will be retrofitting each IMP
+and TIP with additional core memory.  At the end of the retrofit
+program, the memory sizes of the various machines will be as follows:
+
+   IMP (516 or 316) - 16K words
+
+   TIP - 28K words
+
+   TIP with Magnetic Tape Option - 32K words
+
+In addition, the expansion of the TIP core memory will necessitate
+enlarging the TIP to two cabinets.
+
+Listed below is the schedule for the remaining retrofits.  We have
+arranged this schedule to coincide with usual monthly Preventive
+Maintenance at each site so as to minimize user inconvenience, but the
+work required will frequently require the machines to be down longer
+than normal.  I will issue additional RFC's updating this schedule as
+necessary.
+
+Any site which anticipates difficulty with the expansion of TIP size,
+and thus the floor space requirement, should contact Hawley Rising (BBN)
+at
