Keyboard The Model 712 workstation uses a Hewlett-Packard PC keyboard. You may need to know the differences between the PC Keyboard and the Hewlett- Packard ITF Keyboard (HP 46201A/B Keyboard). Aside from the obvious difference in the appearance of these keyboards due to the different arrangement of the keys, there is also a difference in the keys and their output codes. Some keys on one keyboard (the ITF keyboard for example) may not exist on the other keyboard. These keys generate codes which also may not exist as output from the other keyboard (or may be generated by a different key). Codes that are generated when a key is pressed are called keycodes. Some applications expect to use keycodes generated by keys existing on one of the keyboards (the ITF keyboard for example). Since the keys do not exist on the other keyboard (the PC keyboard for example), an accommodation must be made if the PC keyboard is to be used. In most cases, it is still possible to use some other key that is equivalent (generates the same keycode from a different keycap). To do this, it is necessary to know which keys are equivalent on the two keyboards. Table 1-2 compares the equivalent keys on the ITF and PC keyboards. NOTICE: Keyboard keys not mentioned in Table 1-2 are the same on both keyboards. Product Information 1-13

Keyboard
The Model 712 workstation uses a Hewlett–Packard PC keyboard.
You may need to know the differences between the PC Keyboard and the Hewlett–
Packard ITF Keyboard (HP 46201A/B Keyboard). Aside from the obvious difference
in the appearance of these keyboards due to the different arrangement of the keys,
there is also a difference in the keys and their output codes. Some keys on one key-
board (the ITF keyboard for example) may not exist on the other keyboard. These
keys generate codes which also may not exist as output from the other keyboard (or
may be generated by a different key). Codes that are generated when a key is pressed
are called
keycodes
.
Some applications expect to use keycodes generated by keys existing on one of the
keyboards (the ITF keyboard for example). Since the keys do not exist on the other
keyboard (the PC keyboard for example), an accommodation must be made if the PC
keyboard is to be used. In most cases, it is still possible to use some other key that is
equivalent (generates the same keycode from a different keycap). To do this, it is
necessary to know which keys are equivalent on the two keyboards. Table 1–2
compares the equivalent keys on the ITF and PC keyboards.
NOTICE:
Keyboard keys not mentioned in Table 1–2 are the
same on both keyboards.
