KeyF - Fully supported device. When pertaining to disks, indicates that the disk can be the system disk. Regarding magtapes, it can be the distribution load device. S - Supported as a user device only. When pertaining to disks, it indicates that the disk cannot be the system disk, but can be used for user file storage. Regarding magtapes, it cannot be the distribution load device because this device cannot handle full size reels. O - Obsolete device. A driver is provided, but the device is not supported. Use of these devices is not recommended. No warranty, no SPR accepted. N - Not supported. NotesThe ULTRIX-11 Operating System will operate with a minimum of 192KB of memory; however, 256KB is the practical minimum memory size. Some large programs, like VI and F77, may not run on 192KB systems. The ULTRIX-11 Operating System supports up to 3.75MB (4MB - I/O page) of main memory. A minimum of 512KB of memory is required to take full advantage of the mapped buffer feature (system performance improvement). The DL11-W includes a KW11-L clock. Most terminals can be used as the system console, but a terminal that can produce hard copy output is recommended. Upper case only terminals cannot be used as the console terminal. If the LA120 is used as the system console, the auto disconnect feature should be disabled. These devices are not normally configured on the PDP-11/70. Only a single TS11/TU80/TSV05/TK25 tape drive is supported. DL11 includes all versions of the DL11 used as single line units. Also includes the DLV11 on Q bus processors. Also includes the second single line unit supplied with the Micro/PDP-11, PDP-11/23, PDP-11/23-PLUS, PDP-11/24, and PDP-11/44. Modem control option for the DH11. One dual RX02 drive supported. 18-bit addressing only. On Q22bus processors, the RX02 can only be accessed via the ULTRIX-11 buffered I/O mechanism. The physical (RAW) I/O system cannot be used to access the RX02. For RL01, two drives are required; for RL02, two drives are recommended. The LP11 line printer driver supports only a single unit. The ULTRIX-11 Operating System kernel floating point simulator allows programs that execute floating point instructions to run on processors without floating point hardware. However, floating point hardware is highly recommended for intensive floating point applications and/or where performance is a factor.
