IBM 7090控制台

IBM 7090IBM 709英语IBM 709大型计算机的第二代晶体管计算机版本。设计目的是用于“大规模的科学与技术应用”。IBM 7090是IBM 700/7000 系列英语IBM 700/7000 series科学计算机的第四名成员。1959年12月,IBM 7090首次被安装。[1] 在1960年,一套系统的售价通常为$2,900,000(相当于2023年的$19818701 ),租金为$63,500每月(相当于2020年的$434,000)。

IBM 7090使用36位英语36-bit系统,且带有一个32,768的地址空间(15位地址)。它以2.18 μs的基本储存器周期运行, 且使用了来自IBM 7030英语IBM 7030(Stretch)项目的IBM 7302英语IBM 7302磁芯记忆体技术.

IBM 7090的处理速度约为100 FLOPS[2]比IBM 709快6倍,且租金较IBM709低一半。[3]作为IBM 7090的升级版,IBM 7094较IBM 7090的运行速度快两倍。在1969年7月14日,IBM 7090与IBM 7094都停止了销售,但其操作系统在这之后的十年中依然可以使用。[4][5]

IBM 7090使用了50,000多个锗合金晶体管英语alloy-junction transistor和(更快的)锗扩散节[6] 扩散基极晶体管英语drift-field transistor[7]

输入/输出

The 7090 series features a data channel architecture for input and output, a forerunner of modern 直接记忆体存取 I/O. Up to eight data channels can be attached, with up to ten IBM 729英语IBM 729 tape drives attached to each channel. The data channels have their own very limited set of operations called commands. These are used with tape (and later, disk) storage as well as card units and printers, and offered high performance for the time. Printing and 打孔卡 I/O, however, employed the same modified unit record equipment英语unit record equipment introduced with the 704 and was slow. It became common to use a less expensive IBM 1401英语IBM 1401 computer to read cards onto 磁带 for transfer to the 7090/94. Output would be written onto tape and transferred to the 1401 for printing or card punching using its much faster peripherals, notably the IBM 1403英语IBM 1403 line printer.

Later IBM introduced the 7094/7044 Direct Coupled System; the 7044 handled 假脱机 between its fast 1400-series peripherals and 1301 or 1302 disk files, and used data channel to data channel communication as the 7094's interface to spooled data, with the 7094 primarily performing computations. There is also a 7090/7040 DCS.

Software

[编辑]

The 7090 and 7094 machines were quite successful for their time, and had a wide variety of software provided for them by IBM. In addition, there was a very active user community within the user organization, SHARE英语SHARE (computing).

IBSYS英语IBM 7090/94 IBSYS is a "heavy duty" production operating system with numerous subsystem and language support options, among them Fortran, COBOL, SORT/MERGE, the MAP assembler, and others.

FMS, the Fortran Monitor System英语Fortran Monitor System, was a more lightweight but still very effective system optimized for batch FORTRAN and assembler programming. The assembler provided, FAP, (FORTRAN Assembly Program英语IBM 700/7000 series), was somewhat less complete than MAP, but provided excellent capabilities for the era. FMS also incorporated a considerably enhanced derivative of the FORTRAN compiler originally written for the 704 by Backus and his team.
