Having established a foothold in Unix workstation market with its 68000 family-based News line, Sony Corp wants to shoot the line up-market with a RISC-based top-end, but has not yet decided whether to go for the Motorola 88000. It said in New York last week that it was also looking at the RISC chips from Advanced Micro Devices Inc, MIPS Computer Systems Corp and Sun Microsystems Inc – and may seek to make under licence whichever chip it decides to use. Sony reckons that the workstation market is still immature, and liable to undergo major technical changes.
