MinSoC support even more boards (http://opencores.org/project,minsoc) but there are less supported peripherals there. Ethernet and UART IIRC
The cheapest ones are about $50 or $60. Think the de0-nano is cheapest
If you want to try out some OpenRISC developing without having to buy a dev board, there is also the OpenRISC architecture simulator or1ksim http://opencores.org/or1k/Or1ksim It supports UART through xterm or telnet, ethernet with TUN/TAP and a framebuffer
Or simply the dude who did it owned a DSP1800 as opposed to the board I have at home?
You're actually spot on
I think it was a tight fit though, so I'm not sure it will fit on smaller spartan 3 FPGAs. Disabling caches and hardware mul/div and stuff like that could help. It's a pretty common board, so if anyone is interested in trying, just drop in to #opencores on freenode and chat with us
