Handling Interrupts with any C

Published in the March - April 1989 issue of Micro Cornucopia (Issue #46,) Handling Interrupts with Any C, along with the associated C and Assembler source code, made it possible to register a C function as a hardware interrupt handler.

A multi-tasking kernal had also been written at the time. It allowed a C program to execute functions as parallel tasks from within the main program. Unfortunately, the Interrupt Handling article was too complex for many people. It did not earn enough of a response to justify the publication of the multi-tasking kernel article.

This same experience repeated several times over the next couple of decades and repeatedly re-enforced the lesson learned: Most people are interested in relatively simple issues. They don't want to make the effort to deal with the much more difficult issues that arise from time to time.
