HP 98287 A Graphics Display Station Interface
Note
The Graphics Display Station's
HP-HIL
Interface is not
currently supported by any Series 300 operating system.
Therefore, you do not need to change the
HP -HIL
select
code switches (SW1), even if you have two Graphics Display
Stations. Leave them set to 31, as shown in Figure 5-1, and go
on to step 3.
3. Set the Frame Buffer Address.
SKIP?
If this is the first (or only) Graphics Display Station Interface
you are installing, you can skip to step 4. Your frame buffer
address is preset to $300000 (in hexadecimal), as shown in
Figure 5-1, and need not be changed.
a. Find the set of eight switches labeled SW2 on the Graphics Display
Station Interface (see Figure 5-1). Switches 1 and 2 in this group
determine the frame buffer address.
b. Set these switches to one of the following values, keeping these
restrictions in mind:
• If you have both a Graphics Display Station and a Series 300
bit-mapped display, do not use fraIne buffer address $200000 .
• If you have a Model 320 computer, do not use frame buffer address
$800000 or $900000.
