The IBM Personal System/2 Model 80 Technical Reference (cover title) is IBM's 88-page model-specific interface reference for the PS/2 Model 80 (8580), First Edition, May 1988. It covers the Type 1 (16 MHz) and Type 2 (20 MHz) system boards, identified by model byte F8 and submodel 00 or 01 (Figure 1-1, p. 1-3), and is to be used with the PS/2 Hardware Interface Technical Reference and the PS/2 and PC BIOS Interface Technical Reference. The April 1987 single-volume book and the October 1990 edition are also hosted.
