    • A modular read-write and read-only memory unit capable of employing both direct and indirect decimal and symbolic addressing, a central processing unit capable of performing both serial binary and parallel binary-coded-decimal direct and indirect memory register arithmetic, and an input-output control unit capable of bidirectionally transferring information between the central processing unit and a number of input and output units are controlled by a microprocessor included in the central processing unit. The input and output units include a keyboard input unit, a magnetic card reading and recording unit capable of bidirectionally transferring information between an external magnetic card and the read-write memory unit, and a solid state output display unit capable of displaying three lines of numeric information. The memory, central processing, input-output control, input, and output units are employed to provide an adaptable programmable calculator that may be operated manually by the user from the keyboard input unit or automatically by a program stored in the read-write memory unit. The calculator may also be employed to load programs into the read-write memory unit from the keyboard input unit, to separately transfer either data or programs bidirectionally between the read-write memory unit and an external magnetic card, and to code programs stored in the read-write memory unit as being secure when they are transferred to an external magnetic card, thereby preventing users of the calculator from re-transferring them to an external magnetic card or obtaining any indication of the individual program steps once they are reloaded into the calculator.
    • 一种能够采用直接和间接十进制和符号寻址的模块化读写和只读存储器单元,能够执行串行二进制和并行二进制编码十进制直接和间接存储器寄存器运算的中央处理单元和输入 - 能够在中央处理单元和多个输入和输出单元之间双向传送信息的输出控制单元由包括在中央处理单元中的微处理器控制。 输入和输出单元包括能够在外部磁卡和读写存储器单元之间双向传送信息的键盘输入单元,磁卡读取和记录单元以及能够显示三行数字的固态输出显示单元 信息。 存储器,中央处理,输入输出控制,输入和输出单元用于提供可由用户从键盘输入单元手动操作或由存储在读写存储器单元中的程序自动操作的适应性可编程计算器 。 还可以使用计算器将程序从键盘输入单元加载到读写存储器单元中,以便在读写存储器单元和外部磁卡之间双向单独地传送数据或程序,并对存储在读写存储器单元中的程序进行编码 读写存储器单元在被传送到外部磁卡时是安全的,从而防止计算器的用户重新传送到外部磁卡,或者一旦重新加载到计算器中就获得各个程序步骤的任何指示 。

    • A programmable control unit for disk memory and controller comprising a microprocessor (MPU), random access memory (RAM) used as a buffer to cache disk resident data used by a data processing system (DPS), and a configurable data path (CDP) which couples the DPS to the disk controller. The (MPU) is programmed to provide the DPS rapid access to disk resident data by so controlling the CDP as to maintain a memory cache of disk resident data in the RAM. Data is cached under either directed control via an application level task or operator console directive, or under dynamic control through which a predetermined number of successive blocks of data are read from the disk and stored in the RAM each time any one block is addressed, and once the RAM is full, by discarding from the RAM a block of data which the immediate history has shown is least useful.
