Jumba's computer is a machine that Jumba constructed (or upgraded) to show pictures of the experiments and information on their number and primary function. It can also reveal an antidote for any experiment's power or effect on a person. The experiment's info can also be shown on Lilo's computer and told on Gantu's experiment analyzer.
Jumba's computer displays crude 2-D representations of the experiments, along with specific information on them and occasionally antidotes for the experiments' effects. Jumba also keeps self-made video diaries explaining his thoughts or the results of his illegal experiments (as displayed in "Frenchfry").
