The Fujitsu K-6000α series of office computers was the successor to the K-6000 series. Together with the K-1500α series of office workstations, Fujitsu announced nine lines and 26 models*1 in November 1994. The K-6000α series was positioned as business servers*2 that provided client-server work environments by networking PCs and servers together. In terms of features, the K-6000α series extended the substantial functional upgrades*3 made to the K-6000α series in October 1993.
Features of the K-6000α series:
- (1) Field upgradable
- (2) New BS*NET software
- (3) Enhanced processors and more main memory capacity and disk capacity
The following features apply to all models except the K-6500α DT models:
- (4) All models were standard equipped with mirrored disks
- (5) Connectable to 100 Mbps high-speed LANs that support the fiber distributed data interface (FDDI)
- (6) Standard equipped with a 230 MB double-density magneto-optical disk drive
- *1. The K-6000α series consisted of three lines and 13 models (see table below). The K-1500α series consisted of six lines and 13 models (K-1300α/10, 30; K-1600α/10, 20, 30; K-1600αNB/05, 10; K-1600αNX/05, 10; K-1600αLT/10, 20; K-1600αLX/10, 20).
- *2. Fujitsu’s generic term for business-use servers including office computers and UNIX servers. The K-6000α series shared a cabinet design with the DS90/7000 series of UNIX servers. Fujitsu began using the term business server in October 1993 with the K-6000 series upgrades.
- *3. These upgrades included the joint use of a proprietary 64-bit RISC architecture and the previous CISC architecture and enhanced PC connectivity software (the RDA/SV remote database access software, etc.) and were seen as the precursor to the K-6000α series.
Fujitsu continued to make upgrades to the K-6000α series until November 1996.
