Australian Sparcsystems-builder Graphics Computer Systems Pty Ltd, from Burwood, Victoria in the Melbourne suburbs has a set of Mbus workstation motherboards designed to turn an iAPX-86-based personal computer into a Unix workstation for 20% of the cost of a comparable Sparcstation 20 model from Sun Microsystems Inc. Called the MXPeacemaker, the board fits a standard 5.25 personal computer slot and, like the Opus Systems Inc SparcCard, enables MS-DOS, Windows and OS/2 users to run applications written for Sparc under Solaris. There are two superSparc versions, the S50 and S61 (50MHz and 60MHz), two superSparc 2 boards, the S71 and S91 (75MHz and 90MHz), and three hyperSparc 1 versions, the H901, H1001 and H1101 (90MHz, 100MHz and 110MHz). With support for cut and paste between the personal computer and the Sparc applications, MXPeacemaker will ship in three months’ time with prices starting at around $6,250.
