The algorithm used to tuild

system configuration differs from other
versions., as shown in Figure 2-16.
2.54.4 ASSIGNING INTEGRATED 1052, 1403,
2311, AND 2540 DEVICE ADDRESSES
The microrrogram assemtler system (MAS)
assigns the device addresses shewn in
Figure 2-17.
These standard addresses are
placed in fixed auxiliary storage locations
by the CSI deck.
The device addresses for the integrated
attachrr.ents can te anywhere within the
range of 00 through FF.
'Ihe address to be
used for any integrated attachment can be
changed by changing the contents of the
auxiliary storage location specified for
that device in Figure 2-19.
MAS
inserts FF in the auxiliary storage
location for any of these optional
attachment features not selected in the
Far.ticular core load.
Putting FF in the auxiliary stcrage
location for devices not included in the
core load inhibits the use cf FF as a
device address for any device on the same
channel.
If FF is desired as a valid device
address, the CE or SE must reflace the FF,
inser.ted

not included, with any unused device
address.
This can be done by punching a
card with the beginning data address,
length of data field, and data to be loaded
and by inserting the card in the
~AS
core
load deck.
The detailed instructions for
preparing additional CSL cards are
presented at the beginning of the BCPL
microprogram routine.
For single-unit addresses (SUA), A=O, B=O,
C=O for MPX, and C= 1 for I CA:
