IBM公司最近宣布六个新机型:3083-EX、BX、JX,3081-GX、KX以及3084-QX,直接取代3083-E、B、J,3081-G、K和3084-Q。新机型在内部性能上相对后者提高5％～14％,而价格相同。3081-KX的最大主存容量从48MB扩充到64MB,而3084-QX的主存则从64MB扩充到128MB。新机型取消了热传导元件,采用新的电路,故现有的3080系列机不能现场升级到X型。在IBM MVS/XA,MVS/370或VM/SP的HPO(High-Performance Option)工作环境下,
IBM recently announced the replacement of 3083-E, B, J, 3081-G, K and 3084-Q with six new models: 3083-EX, BX, JX, 3081-GX, KX and 3084-QX. The new model in the internal performance of the latter increased by 5% to 14%, while the price is the same. The maximum capacity of the 3081-KX expands from 48MB to 64MB while the 3084-QX expands its main memory from 64MB to 128MB. The new model to eliminate the heat conduction components, the use of new circuits, so the existing 3080 series machines can not be upgraded to X site. Under HPO (High-Performance Option) work environment of IBM MVS / XA, MVS / 370 or VM / SP,
