Abstract
A microcomputer system uses a standardized S-100 bus with eight bit Data In and eight bit Data Out lines, but has a sixteen bit microprocessor with sixteen bit bidirectional data input/output terminals. An arrangement is provided to cross-connect the Data In lines and Data Out lines for one memory board compared to another, these two memory boards being accessed by the same address. A processor board containing the microprocessor connects the Data In and Data Out lines to the data input/output terminals by controllable unidirectional buffers which criss-cross the bytes on write compared to read operations.
