The goals of the project are to create fast, full-featured simulations of classic computer hardware, help people understand how these early machines worked, make it easy to experiment with different machine configurations, and provide a platform for running and analyzing early computer software.
The first PCjs simulation was C1Pjs, which emulates the Challenger 1P, a 6502-based microcomputer introduced by Ohio Scientific in 1978. C1Pjs v1.0 was released in July 2012. More information about the first release of C1Pjs was posted on the OSI Discussion Forum at osiweb.org.
The next PCjs simulation was PCx86, which emulates the original IBM PC, IBM PC XT, and IBM PC AT, as well as compatible machines like the COMPAQ DeskPro 386. PCx86 v1.0 was released in late 2012.
PCx86 emulates the Intel 8088, 80186, 80286 and 80386 CPUs, and it faithfully renders characters and graphics produced by the IBM Monochrome Display Adapter (MDA), Color Graphics Adapter (CGA), Enhanced Graphics Adapter (EGA), and Video Graphics Array (VGA) video cards.
Support for assorted motherboard and expansion bus components (eg, disk controllers, parallel and serial ports, etc) is available in any appropriately configured machine, along with the powerful built-in PCjs Debugger that provides visual access and control of the simulated hardware.
