Bull SA and Honeywell Bull Inc are to follow their OEM agreement for the previous generation of IBM 3380 disk drives with similar agreements for IBM’s 3990 Model 1 and 2 controllers, and the new 3380J and K drives, the latter of which stores up to 7.2Gb. The microcode in the 3990 has had to be adapted for the 36-bit GCOS 8 mainframes, and it is understood that the partners are not looking at the 3990 Model 3, which supports 4.5Mbyte-per-second channels, at the moment, not only because IBM has hit trouble on the microcode that will delay first deliveries, but also because writing appropriate microcode for the Honeywell Bull machines would be a major undertaking. It is also understood that Bull and Honeywell Bull will be marketing the Teradata Inc DBC 1012 multi-microprocessor fast database search engine for use with DPS 8000 and other GCOS 8 mainframes, and that Honeywell Bull already has one or two US orders.
