Most computer graphics systems in existence today are based upon the direct view, refreshed C.R.T. These systems, for the most part, are fairly expensive, generally costing well over $20,000. The recent availability of high resolution, moderate size, direct view storage C.R.T.s makes possible full computer graphics systems costing under $20,000. This chapter will compare several possible graphics systems based upon the direct view storage tube, and also some systems using the refreshed C.R.T. Emphasis will be on hardware and software tradeoffs permitting lowest system cost, and on the resulting performance and applications for such systems.
