The Null Device

First there was Jeri Ellsworth's 21st-century Commodore 64 and the highly hackable TV game it spawned; and now, a Dutch hacker is building an Amiga in a FPGA chip. Dubbed "MiniMig", Dennis van Weeren's project implements the Amiga's custom chips on the FPGA connected to a 68000 and RAM, and uses disk and ROM images stored in a standard FAT file system on a MMC card. At the time of writing, it is close to completion.
First there was the C-One, the Commodore 64 of the future, and now some hackers are using FPGA chips (i.e., dynamically reconfigurable hardware) to reimplement old arcade game boards, all on a chip; just supply the ROMs. The FPGA designs apparently even have extra "code" to convert the arcade-video-monitor signals to VGA, for those who don't have one of those big glass bottles sitting around.

(This is cool, not just because of the hipness of the the retro-video-game thing; the fact that you can make a small FPGA chip emulate any digital circuit, from a Pac-Man board to a Commodore 64 with an IDE interface bolted onto it, all by downloading the right information into it, is very cool. Now you have hackers creating open-source "hardware" components for FPGAs; i.e., code which, when integrated into a project, makes a complete 6502 core or USB interface or whatever, and others bolting them together to make all sorts of highly miniaturised gadgets. Unfortunately, FPGAs seem to only work for digital circuits, so something like a purely analogue open-source TB-303 core (suitable for embedding into mobile phones, childrens' toys and other gizmos) would not be possible.)
