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 preliminary schedule for these 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 anticipate 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 in the form (month/day)   Xerox (1/3)   SAAC (1/4)   MIT (1/8)   MITRE (1/9)   Harvard (1/15)   RAND (1/16)   ARPA (1/16)   NBS (1/17)   AMES TIP (1/24)   Lincoln (1/24)   Utah (2/1)   UCSB (2/6)   Belvoir (2/8)   NOAA (2/12)   USC (2/13)McKenzie                                                        [Page 1]
