In January 1990, Gassée resigned and his authority over product development was divided among several successors. Many Apple engineers had long been pressing for lower-cost options in order to build market share and increase demand across the entire price spectrum. With Gassée out, a rush started to quickly introduce a series of low-cost machines. Three market points were identified, a very low-cost machine aimed at costing $1,000, a low-cost machine with color graphics, and a more upscale color machine for small business use. In time, these would develop as the Classic, Macintosh LC, and Macintosh IIsi.
