and there are the files, now I dont know when it runs the symbol util if it fires it from disk here or flash or what, but you could probably drop the new symbol on it and see if it runs and change it back. rename the current one, drop in the new, rename it back if it does not work.
I believe, 014 - oscilloscope, 025 - pattern gen, 034 - deep la, the PV_ files are the test files
