1092 and 1093 Programmed Keyboards
1092 and 1093 Programmed Keyboards
These programmed keyboards (Figure 13) provide
for the input of keyed numeric data to the 1050 sys-
tem for either a home-loop or line-loop operation.
When attached directly to a 1050 system, these key-
boards are available in the following configurations:
1092 alone,
1093 alone, or
1092 and 1093 in tandem.
All data entered from these keyboards can be visu-
ally checked before it is entered into the system, be-
cause the data keys pressed (one per column) remain
latched until manually restored. Scanning and trans-
mission of the keyed data occurs when the terminal is
polled, following pressing of the start button. Trans-
mission is at 14.8 cps from any programmed keyboard
configuration, when attached to either a Model 1, 2,
or Nl 1051 Control Unit. When a keyboard configura-
tion is attached to the control unit, this attachment is
made in the reader-I position. A second configuration
can be attached in the reader-2 position, if desired.
The
IBM
1092 and 1093 Programmed Keyboards are
similar in design and operation. Their basic difference
is in the number of columns of data keys provided by
each. Both keyboards are designed to accept vinyl
plastic keymats (templates) with prepunched key loca-
tions, and lettered with the proper key identification
and field designations. The 1092 and 1093 are each
available in two models. The 1092, Model 1, provides
15 columns of data keys and keymat ring supports
which can accommodate up to ten loose-leaf type key-
mats. The 1093, Model 1, provides ten columns of data
keys and does not have keymat ring supports.
Model 2 of both the 1092 and 1093 provides a sens-
ing unit on the keyboard directly below the data keys.
This unit senses up to 48 differently coded keymats
which can each be used individually with these Model
2 keyboards. In addition to having this sensing unit,
the 1092, Model 2, provides 16 columns of data keys
and does not have keymat ring supports. Additional in-
formation on these keyboards is available in, IBM 1092
and 1093 Programmed Keyboards, Form A24-3266.
