The paper computer's method of operation is nominally based on a register machine by Elmar Cohors-Fresenborg, [2] [7] but follows more the approach of John Cedric Shepherdson and Howard E. Sturgis in their Shepherdson–Sturgis register machine model. [8] A derived version of the paper computer is used as a "Know-How Computer" in Namibian ...
BASICs with Bitwise Ops use -1 as true and the AND and OR operators perform a bitwise operation on the arguments.. FOR/NEXT skip means that body of the loop is skipped if the initial value of the loop times the sign of the step exceeds the final value times the sign of the step (such as 2 TO 1 STEP 1 or 1 TO 2 STEP -1).
GW-BASIC allows use of joystick and light pen input devices. GW-BASIC can read from and write to files and COM ports; it can also do event trapping for ports. Since the cassette tape port interface of the original IBM PC was never implemented on compatibles, cassette operations are not supported.
The IBM Personal Computer BASIC, commonly shortened to IBM BASIC, is a programming language first released by IBM with the IBM Personal Computer, Model 5150 (IBM PC) in 1981. IBM released four different versions of the Microsoft BASIC interpreter , licensed from Microsoft for the PC and PCjr .
Adapting BASIC for the Apple II was a tedious job as Apple received a source listing for Microsoft 6502 BASIC which proved to be buggy and also required the addition of Integer BASIC commands. Since Apple had no 6502 assembler on hand, the development team was forced to send the source code over the phone lines to Call Computer, an outfit that ...
TI BASIC is an ANSI-compliant interpreter for the BASIC programming language built into the 1979 Texas Instruments TI-99/4 home computer and its improved 1981 version, the TI-99/4A. In contrast to most BASICs found on contemporary microcomputers , TI BASIC does not trace its history to Microsoft BASIC , but was instead developed in-house ...
Minimal instruction set computer (MISC) is a central processing unit (CPU) architecture, usually in the form of a microprocessor, with a very small number of basic operations and corresponding opcodes, together forming an instruction set. Such sets are commonly stack-based rather than register-based to reduce the size of operand specifiers.
