Doctor Know's computer
Doctor Know's computer was an eldritch, supernatural computer owned by the version of Doctor Know who became a member of the Scottish Division of the Multidimensional Finders Service in the 925th Universe. A “large research computer”, it “stored every bit of data contained in Doctor Know’s extensive library” and could also scan other realities and times. Described as an “eldritch monstrosity that only the man himself understood”, it had “seven layers of keyboards filled with all sorts of symbols and buttons”, many of which were illegible, invisible or worse: one button “required the user to shift their hand through the keyboard into the 4th dimension to hit a button made millions of years in the future by a race known as the Heloiglobians”.
Both Talbot and Tetra-None Hepta-Oct tried and failed to use the computer on one occasion, but eventually had to prevail upon the Doctor himself to make it work after the Hydrant retrieved him from the coffee shop to which he had absconded.
