below.Only the features and facilities that are not standard on a
particular processor are described. For example, the Word Buffer
feature is standard only on thet!odel 148; therefore, the feature number
and requirements are described only for the Models145 and 145-3. • The System Timing facility (12001), which includes the clock
comparator and the processor timer, on theModels 135 and 145. • The clock comparator and processor timer (12001) on the Model 145-3. • The Floating-point feature
--For theModel 135, feature #3900 --For the Model 145, feature #3910 • The Precision Floating feature (13840) on the Model 135-3. • The Channel Indirect Data Addressing feature on each of the 2860, 28 7 0, and 2880 standalone I/O channels on the Model 165 II or 168.
