Section 3 User Interface Specifications
This user system interface board has the function that masks the chip select signals (CS0 to CS7),
bus request signal (BREQ), and wait input signal (WAIT) depending on the setting of a switch.
To use the mask function, set switches (SW1 and SW2) on the user system interface board (figure
2), according to tables 3 and 4, and mask pins.
Note: When the emulation memory function is used, the output of the chip select signals to the
user system is controlled. Be sure to mask the chip select signals (CS0 to CS7) that
correspond to the address area to which the emulation memory has been allocated.

Failure to do so will result in a FIRE HAZARD and will
damage the user system, the user system interface board,
and the emulator product or will result in PERSONAL
INJURY. The USER PROGRAM will be LOST.
