An easy to use hardware emulator. Dioscuri is an x86 computer hardware emulator written in Java. It is designed by the digital preservation community to make sure that documents and programs from the past can still be accessed in the future. Dioscuri is durable and component-based.

Dioscuri is an X86 computer hardware emulator written in Java. It is designed by the digital preservation community to make sure that documents and programs from the past can still be experienced in the future. To do so, this emulator has two key features above any other emulator: it is durable and flexible. Durable because it can be ported to any other computer platform which has a Java Virtual Machine (JVM) without any extra effort. This reduces the risk that the emulator fails to work on one computer system in the future, because it will continue to work on another.
Dioscuri is also flexible because it is completed component-based, just like a real computer. Each hardware component is emulated by a software surrogate called a module. Combining all modules allows the user to configure any computer system (if compatible). Add a new module or upgrade another one and the emulator is capable of running it.

Features:
1. 16 and 32-bit X86-based CPU (real-address and protected mode)
2. 1 MB RAM (expandable)
3. Storage devices: floppy, HDD
4. Input devices: XT/AT/PS2 compatible keyboard, serial mouse
5. Output devices: virtual screen
6. VGA video graphics adapter
7. DMA-support
8. IRQ-handling based on a Intel 8259 PIC
9. Timing mechanism based on an Intel 82C54 PIT and Crystal Clock
10. Real-time clock with integrated CMOS
11. RS232 Serial port based on UART 16550A
12. System BIOS using Plex86/Bochs BIOS
13. Video BIOS using VGA LGPl'ed BIOS
