A term used to reflect the publisher's uncertainty about equipment that will be available to run the disk and its retrieval system. Unless the publisher can require or persuade users to adopt custom workstations, it may be necessary to compromise on memory, processor speed, display resolution, or the use of special hardware such as an image decompression circuit board. A Plain Vanilla Workstation requires trade-offs in disk design that are not necessary when a custom workstation can be assumed.
