The highly-regarded Toshiba Corp T3100 80286-based portable computer has the field to itself no longer – but as longtime campaigners for names rather than anonymous numbers for products, we begin to think that the Japanese had better stick to numbers after all. Mr Mytool LX is the wince-making handle that Ricoh Co has given to its laptop AT-alike, available in Japan from this week at the local equivalent of $3,320, precisely the same as the Toshiba box, which is called the J3100 in Japan. Added value in the Ricoh machine includes a ROM dictionary containg 140,000 Japanese words, much larger than those in rival products. The 80286 machine comes with 1Mb memory, keyboard and mouse, gas plasma display, twin 3.5 floppy disk drives and MS-DOS 3.1. It weighs 14 lbs 5 oz, and Ricoh is pitching it as the wife’s runabout in two-computer families, and looks to sell Mr Mytool at a rate of over 3,000 a month. There is no word on European or US plans.
