IMP/TIP Memory Retrofit Schedule (Revision 2)

This revision contains two types of changes to RFC #447. First, the retrofits to Utah, Belvoir, NOAA, USC, Stanford, ISI, Case, and CCA have been completed and are therefore removed from the schedule. Second, the retrofits to UCSB, ETAC, Aberdeen, and Rome have been rescheduled.

The revised text of RFC #447 follows:

During the first several months 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 the 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 (617)491-1850 ext. 473 All dates given below are below in the form (month/day)
