Limiting the design to medieval technology means no electricity. They didn’t have a way to create or store significant amounts of charge. You would be limited to mechanical linkages for the operation of the computer and the UI.
You could certainly make predictive mechanical tools like the Antikythera mechanism. In theory you could create mechanical calculators like the stepped reckoner, or even Charles Babbage’s Analytical Engine, though medieval craftsmen lacked the metallurgy and precision fabrication techniques to really make a functioning machine as complex as those examples.
