I just had it pointed out that the last link I sent was just someone using 
their Dreamcast as a shell for a computer; my apologies for not looking 
closely enough, as I'm at my day job. Anyway, I went back to Google to try 
to find a cache for (the currently down) dcdev.allusion.net, which was 
mentioned on Slashdot as having info on this a while back, without luck; 
however, I did find the following link, which does indeed have info on the 
circuitry, linkups, etc.:

Searching for "dcdev" on Google seems to actually be more useful than 
"Dreamcast hard drive".
