specified real address (TYPE1, TYPE2, TYPE3, or TYPE4) ,
or a line adapter if this is an emulator line group (IBM1, TELE2, or BSCA). Only TYPEl is valid for a
device type of 3704. For DEVTYPE=3705, TYPEl or TYPE4 may be coded. In identifying the line
adapter, IBM1, TELE2, or BSCA can be specified only in
relation to another RDEVICE macro that has ADAPTER=TYPE1, TYPE2, TYPE3, or TYPE4. is the 3704/3105 model letter and number, respectively.
The model number determines the size of the 3704/3105 storage. See Figure 11 for a list of the model numbers
and the corresponding storage sizes. You should enter both a letter and a number. However,
if only a single numeric character is entered, an "NOTE is issued and the number is treated as model data for a 3104 or 3705-1, depending on the value of DEVTYPE. 64 IBM VM/370 Planning and System Generation Guide

system IPL time. If an automatic load is not desired,
omit this operan d.
Note: Failure to code the CPNAME operand on the RDEVICE
macro for the 3704/3705 base address causes VM/370 to
mark the device "not operational" at IPL time. The
cluster on that 3704/3705 is therefore unusable.

required for correct operation of VM/370 recovery
