The idea is to make [PC8080](/modules/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 VT-100 terminal emulator, which is -itself is an 8080-based machine. +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 "wired up" to other PCjs machine simulations.
