Welcome to PCjs, home of the original IBM PC in a web browser.
PCjs provides a variety of computer emulators written in JavaScript, including PCx86 for x86-based machines
(up through the 80386), C1Pjs for the 6502-based Ohio Scientific Challenger 1P, PC8080 for 8080-based machines
such as Space Invaders and the DEC VT100 Terminal, and PDPjs for PDP-11 machines from the PDP-11/20 to the PDP-11/70.

The code has already undergone a lot of refactoring. Opcodes are now decoded by function tables rather than a single
switch statement, and every opcode is implemented with a discrete function. Other refactoring includes flag management,
