It should only be necessary to down-load the LSI-11/23 software at the beginning of an observing run or after a power failure. To down-load the LSI-11/23 software type:
DOWN_LOAD
This takes about two minutes, and when successfully completed will print the following on the terminal window:
PASDBG V02.4
%PASDBG-I-NODSM No DSM - target not yet loaded
PASDBG>
%PASDBG-I-BOOT1 Loading Bootstrap
%PASDBG-I-BOOT2 Loading User Image. Please Wait.
PASDBG V02.4
Target stopped at physical (00002056), virtual (002056): JMP @#2422
Executing KERNAL code
No process set, physical mapping in effect
PASDBG>
If it does not print this, the LSI-11/23 was probably already running
and you have just bombed it! Don't panic, just type DOWN_LOAD
again.
