I, 1'.10 I Integrated Emulators Emulator-dependent programs (except for DOS emulation under OS or OS/VS) that execute on a particular System/370 equipped with the appropriate
compatibility features can execute on that System/370 in DOS or as virtual machines under VM/370. Figure 41 shows, by System/370 model number, which integrated
emulators can execute under VM/370 and the compatibility feature numbers
(#xxxx) that are required.
No changes are required to the emulators, to DOS or OS, or to VM/370 to allow emulator-dependent programs to execute in virtual machines. On the System/370 Model 158 only,
cannot operate concurrently with the (17117) • the virtual machine assist feature 7070/7074 compatibility feature
In an Attached Processor (AP) system, a virtual machine can use the SET AFFINITY com!'C.and. to make use of an emuldtol. lustalleci on only one ot
the processors. The Directory option for Affinity may be used instead,
with similar results. 1401 1440 709 S/360 1401 1460 7090 System/370 Model 1440 1410 7070 7094 Model 20 1460 7010 7074 7080 709411 135, 1 35-3, 138 .7520 .4457 145,145-3,148 .4457 #4458 155 11,158 #3950 17117 165 II #7117 .7118 17119 168 17127 17128 #7129

Appendix B. Configuration Aid
Appendix B shows the devices and control units that can be specified in
a V8/310 system generation; they are grouped by use. It lists the
control units, notes the aaximum number that can be specified in the FEATURE= operand of the RCTLUNIT macro, and tells whether or not the
control units can operate on a shared subchannel.
It shows the devices that can be attached to each control unit, and
lists the operands that can be specified for each device in the RDEVICE macro.
The control units and devices are placed in subgroups according to the ways they can be configured. Fer e:ample, the chart of tape devices
indicates that a 2401, 2402, or 2420 can be attached to a 2803 or 2804 control unit. I I I I Type of I Device I RCTLUNIT ISharedl RDEVICE I I Sub- 1----------------- I I Maximum I chan-I I ICUTYPE=I FEATURE= I nel IDEVTYPE=I Other Operands
