The Compaq Deskpro 386s/20 was a 20 MHz update on the original 386s, which was 16MHz originally. The main QOL improvement, besides the 9MHz faster clock-speed, is the addition of on-motherboard 72 pin Fast Page SIMM memory rather than relying on the then aging propreitary memory card format introduced with the original Deskpro 386 in 1986.
