The AT&T-Sun Microsystems announcement on Sun’s SPARC RISC and new Unix standards (CI No 792) has galvanised Arete Systems Corp, San Jose, Cali-fornia into announcing that it will be using the SPARC as the CPU for a new line of high performance products to be introduced during the latter part of 1988. It says it will also continue to offer 68000 family machines and will develop new 68040-based products just as soon as that device is available from Motorola (it has not yet even been previewed). SPARC chips are now or will shortly be available from Fujitsu Microelectronics, Cypress Semiconductor and Bipolar Integrated Technologies. Unisys Corp is still the biggest customer for Arete’s multiprocessors.
