Abstract
The I/O instructions for the Intel 8008 Microprocessor have versatilities that are not apparent to most users. The Standard lament is that there are only 8/sub 10/ input instructions. The fact that there are only 24/sub 10/ output instructions is sometimes belabored, but 24 is normally considered sufficient for most microprocessor applications. This note discusses ways to expand the available number of both these instructions. 4 figures.
