A2 and B2, in "FB-512" refers to the IBM 3310 and 3370 Direct Access storage Devices. "VM/370 hardware assist" refers to both
the virtual machine assist function and VM/370 Extended Control-Program support. Some form of the VM/370 hardware assist
is available on all VM/370 supported System/370 svstems except the 155 II, 165-111, and 4331. Befer to IBM yirtua! Machi!!g Fa£ili:!:'YL37Q: Pla.n.ning ang System. Guide, Order No. GC20-1801, for further device
information on the VM/370 hardware
assist and ECPS features. Any information pertaining to the IBM
2741 terminal also applies to the IBM 3767 terminal, Model 1, operating as a
2741, unless otherwise specified. The term "processor" used in this
publication means the main processor
which is the processor with I/O handling
capabilities. The term "attached
processor" means a processor that has no I/O capabilities; an attached processor
is always linked to a main processor for
utilization. The terms "processor" and
"attached processor" are not to be
construed to mean an operation within a
system complex where both processors are
to perform I/O operations. VM/370 supports I/O on only one processor in a two processor configuration. "3800" refers to the IBM 3800 printing
Subsystem. "3850" refers to the IBM 3850 Mass Storage System. For a glossary of VM/370 terms, see the IBl1 !:gcility/37Q: §lossy'y Index, Order No. GC20-1813. PREREQUISITE PUBLICATIONS The concepts of VM/370 and its four
