"Zoomracks, introduced in 1985, represented data in a form that was visually represented by a filing card, known as "QUICKCARD"s. Cards could be designed within the program as a "template", using general-purpose data fields known as "FIELDSCROLL"s, which could hold up to 250 lines of 80 characters. Cards were collected into a "RACK", which was essentially a single database file. The display was character-based and did not make use of the Atari's GEM interface even though this was the primary platform for the product. Unlike similar database programs of the era, Zoomracks did not support different types of data internally, everything was represented as text."
"When a rack was opened the cards were displayed as if they were in a sort of linear rolodex, and the user could "zoom in", non-graphically, on any particular area to see more details of the cards in that area, and then zoom in again to see all of the fields on a particular card. The racks could display their cards sorted in a variety of ways, making navigation much easier than with a real-world rolodex, which is sorted only by a single pre-defined index (normally last name). Data could be moved from database to database simply by cutting a card out of one stack and pasting it into another. Up to nine racks could be opened at one time." via Wikipedia
