Homebrew Coder Pate who first off released a DOS Emulator for the Nintendo DS, then moved onto the Android has now posted a release of his DOS Emulator for the Raspberry Pi. For those who dont know a Dos Emulator lets you play old PC Games such as Doom, Duke Nukem 3D, Theme park and similiar games from that period, in short an excellent way to play old games on a new device that was never intended to run the game.
The current status of the emulation is as follows:
- CPU: 80486 processor, including the protected mode features (for running DOS4GW games) but without virtual memory support. The emulation runs at a speed of around 20MHz 80486 (which equals a 40MHz 80386) machine.
- Memory: 640KB of low memory, 4MB of EMS memory and 16MB of XMS memory.
- Super-VGA graphics, with a maximum resolution of 640×480 with 256 colors.
- SoundBlaster 2.0 (including AdLib-compatible FM sounds) sound card.
- US keyboard.
- Two-button mouse.

I dont recall 386’s being half the speed of 486’s in processing power terms. Back in the day an AMD 40MHz 80386 PC was as fast as an Intel 80486 at 33MHz. It was when the 80486 went “DX2” with an internal clock of 66MHz that performance started to ramp up. But I might be wrong of course!
