Hardware Release Notes
B.1 ALPHAbook 1 (Alpha Only)
B.1.6 Audio Support
The DECsound utility included with DECwindows Motif Version 1.2-3 does not
support the sound processor on the ALPHAbook 1 system. Audio support is
available on the OpenVMS Multimedia services kit, a separately licensed layered
product available from Compaq.
B.1.7 Keyboard Mapping
The ALPHAbook 1 keyboard is an 88-key, PC layout keyboard. The following
notes describe how to set up the keyboard and enable particular key functions.
Keyboard Setup
You can set up the keyboard either to follow the engravings or to map the keys
in a manner that makes it easier for you as an OpenVMS user. To set up your
keyboard either way, do the following:
1. Click on Options in the Session Manager box.
2. Select Keyboard from the list of options.
3. Select one of the following LK443 or LK444 keyboard types:
• A keyboard type with the suffix _PC maps the keyboard to follow the
engravings, for example, US_LK443AA_PC.
• A keyboard type with the suffix _LK sets the keyboard to
follow the LK-style mapping common to OpenVMS systems,
for example, US_LK443AA_LK.
The procedure for setting up your keyboard is the same as that required for all
current AlphaServer and AlphaStation systems. The only difference is that the
ALPHAbook 1 keyboard does not have all of the keys directly on it. (The next
section describes how to generate those missing keys.)
You can also attach an LK411 (LK401 layout) compatible keyboard or a PCXAL
(PS2 layout) keyboard directly to the AlphaBOOK 1 computer using the mini-
docking station.
Key Functions
When mapping to an LK-style keyboard, note the following:
• The right ALT key does not transmit any code. Instead, the keyboard
controller generates missing LK-style keys when you press it in combination
with this key. These alternate keys are engraved in grey on the keyboard.
For example, pressing RIGHT-ALT-U ([grey 4]) provides the function of KP4.
Note
By default, the right ALT key is set for the special functions described in
the ALPHAbook 1 User Guide (such as increasing or decreasing display
brightness). To set the right ALT key to perform different functions so
you can emulate a LK-style keyboard, you must change this setting at the
console level by entering the following command at the console prompt:
>>> SET HOTKEY OFF
After you enter this command, either enter the INIT command or
powercycle the system. You can then use the right ALT key to perform
the LK-style keyboard actions described in this section.
