High Quality Content by WIKIPEDIA articles! The RISCstations were based on a modified Jazz architecture licensed from MIPS Computer Systems, Inc. (and which was originally designed by Microsoft). Although architecturally similar to contemporaneous Intel 80386-based personal computers (including, for example, a PCI bus), the RISCstations were faster than the Pentium-based workstations of the time. Although based on the Jazz design, the RISCstations did not use the G364 framebuffer, instead using a S3 968-based video card or a 3Dlabs GLiNT-based adapter in a PCI slot.
