Question: Not able to get the emulator running from Sparc station.

Answer: If you are using Sun OS, then there are couple of tests you could do such as:
(1) make sure you are using Version 1.10 emulation tools for Rev3.0 silicon.
(2) check to see if the switch on the box is set to IDnumber 4. (3) Halt the machine as root, and run the command 'probe -scsi' WITH the emulator turned ON. The resulting message will tell you whether the emulator is tied to port#4 or not. If you are using Sun Solaris, only root can execute the XDS510 commands. To get around this, you can execute the following script:
**** BEGINNING OF SCRIPT ****
#! /bin/csh -f
# you must be root in order to execute this installation
# You MUST do a change directory to the place which contains
# the emulator executables before you execute this script.
# This script makes the chmodS that allow for use in Solaris.
foreach file ( emurst mpemu ppemu pdm mvp510ws.out composer board.cfg )
if ( -e $file ) then echo " fixing: $file"
chmod 6755 $file
chown root $file else echo " Skipping file: $file"
endif
end
***** END OF SCRIPT *****
