Space Invaders (Under Construction)

This is the first test of PC8080, a new 8080-based machine emulator being added to the PCjs Project. It's a work-in-progress, so there's not much to look at yet. And the goal is not to build yet-another Space Invaders/Arcade Machine emulator -- that's been done many times over -- but to start with a well-understood 8080-based machine architecture that doesn't need a lot of peripherals, and use it as the first test case for another CPU that we can add to the PCjs toolbox.

The idea is to make PC8080 sufficiently configurable so that it will work with a variety of 8080-based systems, including those with memory-mapped video displays (like Space Invaders), as well as simpler terminal-based systems, like the CP/M-based systems of old.

In fact, as soon as Space Invaders is working, my next adaptation will be a DEC VT100 terminal emulator (itself an 8080-based machine) which can then be "wired up" to other PCjs machine simulations.
