Figure 3-1. Series 300 Interface Card
There are two switches (Sw-l and Sw-2) on the I/O card. These switches
set the select codes for the HP-HIL interface of the HP 98700 and for
the frame buffer RAM control space of the HP 98700. Switch 1 is a five
section switch that sets the HP-HIL. Switch 2 is an eight section switch
that sets the location of the HP 98700 control space and frame buffer.
Sw-l sets the external select code (0 to 31. Note: Select Codes 0-7 are
reserved for internals, and Select Code 9 is for RS-232.) that the HP-
HIL of the HP 98700 will respond to. Sw-l, 1 is the msb and the SW-l, 5
is Isb. Pushing a switch towards the back plate sets the bit to 0, pushing
it away from the back plate sets the bit to 1. Factory setting is Select
Code 31.
