Sequent Computer Systems Inc says that one in five of the systems it shipped last year were Windows NT. Sequent also says it is at a loss to understand how Santa Cruz Operation Inc will support multiple ccNUMA implementations in UnixWare following the agreement Santa Cruz supposedly reached with vendors some weeks ago. To its mind, Santa Cruz still doesn’t understand that it has lost the low-end battle to Windows NT and says that while it will support a UnixWare interface, it believes its own Dynix/ptx to be some six years ahead of where UnixWare is today.
