The venture capital investors who put up $18m in three rounds of venture funding for EnMasse Computer Corp, Acton, Massachusetts, have pulled the plug on the company, and it ceased operations last week, laying off 44 of its 50 employees. EnMasse is seeking to sell its transaction-intensive Unix multiprocessor technology, with Toltec Computer Corp, Scottsdale, Arizona, top of the list of potential buyers – Toltec announced at the end of last year that it was putting the Pick operating system onto the En-Masse E/CS-1 to run concurrently with Unix (CI No 580). Olivetti SpA holds a 30% stake in Toltec.
