It depends on how you want to use the bike - ie. are you just riding for recreation, doing triathons, racing criteriums, etc. It's not as though terrain has changed a lot in the past 20 years, and the bikes all worked fine then. But if you're racing or doing serious training with others on bikes with modern drive trains, then yes, you might need to upgrade. Or get crazy strong.
Back to your original question - there was a thread putting computers on vintage bikes a couple/few months ago. The search function should find it.
