An increasing number of libraries are purchasing terminals from sources other than the vendor of their turnkey systems. It is not surprising because the savings can be considerable, especially if equipment is ordered by mail from a reliable supply house. For example, the Wyse 50 terminal, which can be used on many turnkey library systems because it emulates Televideo 910/919/925, ADDS Viewpoint, and Hazeltine 1500 terminals, costs only $510 when purchased in quantities of three or more. The Wyse 85 terminal, which emulates the Digital VT 220, is available for approximately $550. The Tatung TVT 7220, a Digital VT 220 look-alike, is priced at less than $500. The prices quoted are for 14-inch, non-glare, dark-tinted screens. The increasingly popular amber display versions cost approximately five percent more.
The best source for ads are the computer magazines which focus on specific manufacturers such as Data General, Digital, etc. Purchasers should confirm that the equipment is new and covered by the manufacturer's warranty.
