I know I have owned a bunch. Have switched over a bunch to regular electronic ignition when the computer failed as well.
The computer either worked or it didn't though. Never had one give problems other than dying.
If the car still has one that is in working order after all this time it is not likely to give any problems as the newer orange boxes sold by ma mopar now.
If there is an issue with it, or someone wants to change the setup from stock, then they have to go.
