An electronic computer including microprocessor means, memory means and Input/Output (I/O) means wherein the I/O means comprises a retractable optical fiber connector assembly. The retractable optical fiber connector assembly includes a rotatable spool and a pair of optical fibers for being wound thereabout, these fibers in turn optically connected to optoelectronic means within the computer (as part of the I/O means). On the opposing ends of these optical fibers are desired connectors (e.g., those of the push-pull variety) for being connected to associated optical-type connectors which in turn may form part of various peripheral equipment (e.g., MODEMS, printers, etc.) or other computers to which this computer may be connected.

Methods of applying LSI and microprocessors to the design of microprocessor-based LSI implementation of mainframe processors are described. A mainframe instruction set is partitioned into two or more subsets, each of which can be implemented by a microprocessor having special on-chip microcode or by a standard off-the-shelf microprocessor running programs written for that purpose. Alternatively, one or more of the subsets can be implemented by a single microprocessor. In addition, a subset of the partitioned instruction set can be implemented by emulating software, by off-chip vertical or horizontal microcode, or by primitives. But, however partitioning is implemented, the end result thereof is to keep the critical flow paths, associated with the most frequently used instruction subset, as short as possible by constraining them to a single chip. The application of this method requires partitioning that makes each identified high performance subset executable on one microprocessor in the current state of technology, a way to quickly pass control back and forth between all of the microprocessors, a suitable way to pass data back and forth between all of the microprocessors, and a technology in which it is economically feasible to have several copies of a complex data flow and control store mechanism.

Methods for partitioning mainframe instruction sets to implement

A method of transferring information between a host data processing system and the private storage media of an interactive text processing system, and the reverse, under control of the host while the text processing system is emulating a host terminal. All information intended to be written to or read from the text processor's diskette and commands therefor, are marked with a unique indicator that is recognized by emulation software and utilized thereby to steer said commands and information to a file transfer program and away from the emulated terminal screen. This is done in a manner that is transparent to the host which handles transferred information as though it were being written to or returned from the emulated screen.

Method for controlling the file transfer capability of an interactive

A method of transforming a first editable form of a document prepared by an interactive text processing system into a second and incompatible editable form for use in another interactive or batch text processing system through the use of a transform mechanism is described. A significant step of this method requires the identification of a limited number of key state variables, whose values collectively identify the necessary state information for transforming the first document form to the second. After the key state variables have been identified, the actual number of combinations thereof is determined. For each first document form input item encountered by the transform mechanism, and for each combination of key state variables in which that input item can be encountered, one or more output items for the second document form is explicitly defined as the transform thereof. In addition, the state of the transform mechanism after each such transform has occurred, must also be specified. The described method is also to resolve the actual state that exists at the start of each document. It is also adapted to handle sub-documents, such as margin text, existing within a document to be transformed.

A method of transforming a first editable form of a document prepared by a batch text processing system into a second and incompatible editable form for use in another batch or an interactive text processing system through the use of a transform mechanism is described. A significant step of this method requires the identification of a limited number of key state variables, whose values reflect information concerning source document controls that have been read in a sequence thereof. The next step requires a definition of control compatibility, which source document controls are compatible with other source controls that set the state variables to their current values in that sequence. After control compatibility has been determined, it will be necessary to define the output items that need to be written for the target document as part of the transformation of any possible input sequence. In the next step, with respect to the output items thus defined, an ordering or hierarchy of these items is established so that they will be uniformly handled in the transformation. Then, for each possible output item, determine a set of rules which will govern when and if that output item gets written to the target document based on the value of the key variables in response to a particular set of input items that have been read from the source document. The output item is written if any one or more of the rules is satisfied. Text, when encountered, is defined as always ending a sequence and thereby initiating a write, if appropriate, to the target document of the transformation of the preceding sequence of controls.
