IBM System/370 145 Manual page 220

• Alternate and multiple console support, including graphic consoles
• Extended debugging capabilities as offered by the generalized trace
facility (GTF)
In addition to supporting a wide variety of general and specific
application programs, OS MFT and MVT also support Model 145 features
such as extended preCision, block multiplexing, rotational position
sensing for the 3330-series and 2305, and a remote 3210 Model 2 as an
alternate or an additional console. The Model 30 or 40 OS user can now
use integrated instead of stand-alone 1400/1010 emulation and, like the
DOS user, will benefit from the expanded hardware capabilities--faster
internal performance, more and faster channels and I/O devices, larger
processor storage, etc.--offered by the Model 145.
Because extensive hardware and programming systems compatibili~y
exists between the System/310 Model 145 and System/360 models, most
Model 30 and 40 users can upgrade to a Model 145 (in Be mode) with a
minimum of effort. This is also true for users of
ASP
(Asymmetic
Multiprocessing System) who wish to upgrade a Model 40 support processor
to a Model 145. Essentially. no more effort may be" involved in the
Model 145 installation process for OS MFT <and MVT) users and DOS
Version 3 users who do not convert to OS than is required currently to
change from one operating system release to another, or to regenerate an
operating system to include new hardware, new I/O devices, and more
control program options. In most cases, the fact that an OS MFT or DOS
Version 3 user is upgrading to a Model 145 should not add to the effort
that would be required if new applications were to be added and system
changes were to be implemented for a Model 30 or 40 upgrade to another
System/360.

AND ~ TRANSITION
A system generation must be performed using OS Release 20.1 or later
in order to obtain an opera"ting system designed to support new Be mode
Model 145 features. The OS starter system can be used on a System/360
or a System/370 in Be mode, and a control program for either a
system/370 (BC mode only) or a System/360 model can be generated. The
existing system generation job stream can be used, with the following
modifications, as appropriate:
• Direct access space allocation for operating system data sets will
have to be adjusted as indicated in IBM System/360 Operating System,
System Generation (GC28-6554). If a 3330-series drive or a 2305 is
to be used as a system residence device, UNIT parameters in job
control statements must be changed where necessary •
• stage I input must be modified to reflect the Model 145
configuration, including the presence of any new I/O devices or
features, such as the 3211, the 3330-series, the 2305, integrated
emulator programs, etc. Other control program options, such as I/O
RMS, OLTEP, and performance improvement features, can be included.
• FCB and UCB images should be added to SYS1.IMAGELIB if a 3211
Printer is included in the configuration. User-written output
writer procedures should be modified to include these
specifications.
An OS MFT or MVT operating system generated for the Model 145
includes the fOllowing:
• A nucleus designed to operate in the BC mode fixe~
processor storage
area of the Model 145. MCR, CCH, OBR, and SDR routines are
included.
