The 3151 IBM ASCII Display Station is a stand-alone, high-quality, 14-inch, monochrome display station used for displaying up to 3,300 characters and for entering data into and retrieving data from a host processor. The IBM 14-inch monitor has an actual viewable screen size of 11.4 inches when measured diagonally. The 3151 also communicates with the 128 7-bit ASCII/ISO character set or the 256 8-bit ASCII/ISO character set, depending on machine mode and language. The 3151 is offered in a range of models featuring an asynchronous communication interface with a 7-bit or 8-bit word length, using RS-232-C (CCITT V.24/28) interface expandable to additional RS-422-A (CCITT V.11) interface. The 3151 provides a native mode, 3101 mode, and various emulation modes that allow the 3151 to attach to a variety of host processors. The 3151 native mode is compatible with the native modes of the 3161 or the 3162 with limitations.

Model Abstract 3151-310

The 3151 IBM ASCII Display Station Model 310 offers Green phosphor colors. The Native mode is a superset of the IBM 3161 ASCII Display Station. The Model 310 is 316X compatible, has a 102-key keyboard, and has Customer-recappable keytops. Keycaps are available as an accessory. The 12 F-keys are shiftable to 36 and are definable by the operator or host. The Model 310 comes with three PA (Program Access) keys and ten non-IBM emulations are included in base model. It offers optional RS-422-A communication with speeds up to 38.4K bps. The Model 310 has 3101 Model 23 or Model 881 emulation, a cartridge for additional attachment capabilities, 80/132-character column display, split screen capability (three horizontal viewports), and bidirectional data at auxiliary port, with passthrough to and from the 3151 main port.

Model Description 3151-310

The 3151 Model 31X displays 1,920 (80 by 24), 2,000 (80 by 25), 3,168 (132 by 24) and 3,300 (132 by 25) characters. An alphameric character is represented in a character cell of 9 x 15 or 9 x 14 dot matrix. The data displayed uses the 128 characters of the 7-bit ASCII/ISO codes and an additional character set containing 24 line-drawing graphics, ten script characters, and ten subscript characters. A line drawing character is represented in a 9 x 15 or 9 x 14 dot matrix to create a contiguous line. Character-transmission or Echo-transmission mode provides the capability to transmit a character over a communication line upon depression of each key. The block transmission mode, selectable at setup time allows buffered transmission of data.

.Emulation Modes In Models

3101 mode of Model 31X provides emulation of 3101 Model 881 or 23. Ten non-IBM emulation modes of the 3151 Model 31 provides emulation of ten non-IBM ASCII terminals (TeleVideo 925/925E/910/910 PLUS /912/920, HZ1500, ADDS VP A2 and ADM 3A/5).
