A Minicomputer/Microprocessor Programming Interface
Abstract
A unique solution to the problem of a microcomputer development system is described here. Special-purpose hardware was built for communications between the Motorola 6800 microprocessor and the MODCOMP IV computer. This hardware allows for the transmission of 8 bits of data in either direction at the initiative of the microprocessor. Computer programs were then written for both the microprocessor and the minicomputer to permit the use of the microprocessor Loader and Assembler on source and binary program files stored on the MODCOMP. This system allows the programmer to take advantage of the editing, disc storage and high speed line printer capabilities of the MODCOMP while using the actual M6800 Loader, Assembler, and MPU. Sufficiently fast and reliable data transfer rates were achieved such that this system has provided us with an effective development tool. Further, by additions to the programs in the two machines, this interface can easily be expanded to include the M6800 Macro Assembler and Link Loader.
