technologies to achieve printing speeds
up to 20,040 lines of copy per minute. VM/370 allows virtual machines,
including virtual VM/370, to attach the 3800 printer as a dedicated I/O device
and a spooling device. Release 6 also

starter system before performing a full
system generation. In addition, the BACKSPAC, CHANGE, QUERY, SPOOL, and START CP commands have been modified to
support the features of the 3800 printer. (See "Section 2: Initiating VM/370 Operation"). SUPPORT FOR THE IBM 3850 MASS STORAGE SYSTEM Hardware and Programming Support VM/370 supports user minidisks on Mass Storage System 3330V volumes, where the
minidisk appears to the virtual machine
to be defined on a permanently mounted
IBM 3330-1 drive. MSS volumes may also be dedicated and
attached to a virtual machine as either 3330V or 3330-1 devices.
In addition, the new command DEFINE has
