Clever people, those Japanese. > No. Twere invented by the US arm of the British firm (at the time) Inmos. Thank a fellow named S. Sheffield Eaton. This is also where the ubiquitous "nibble mode" was invented. For DRAM ultra-trivia fanatics, which Japanese company bought the rights to produce the very fast 64K, 256K, and 1Mbit DRAMS that Eaton et al (Inmos) designed and prototyped? NMB Semiconductor. Their ads brag about speed speed speed. -- -- Mark Johnson MIPS Computer Systems, 930 E. Arques, Sunnyvale, CA 94086 (408) 991-0208 mark@mips.com {or ...!decwrl!mips!mark}
