Upgrading the Memory on a DreamCast?

dknight asks: "Ok, a friend of mine recently has his computer die on him. Rather than go out and buy a computer, we thought we'd try converting his DreamCast to fit the bill. We've got the keyboard and mouse, and now have Linux running on it successfully(we're working on getting the network adapter). The problem we're running into, however, is that it's REALLY painfully slow. I'm figuring this is due to the meager 16 Megs of RAM it comes with. My question is: Is it possible to upgrade the RAM on a DreamCast? Has anyone else attempted this feat?" I highly doubt this is possible, but if this can be done, this might breathe new life into those unused DC consoles that are lying around.

Dreamcast != PC

OK, while I'm all for bizarre uses of neat hardware with geek-appeal, you may well be doing your friend a disservice by trying to move him from a PC to a Dreamcast. The first issue I see here is connectivity; you've gotta have it or you're better off just locking him in a closet somewhere with a flashight and a pad of paper.
Having watched the traffic on the dreamcast-linux mailling list devolve into people spouting noise about how someone should just auto-magically develop firmware and drivers for the WinModem and everyone begging for a BBA for less than $150, I have to say that things are lagging. Without a real option for stand-alone connectivity on the dreamcast, you're screwed. Play rogue all you want, but when your friend is done typing his papers in vi he's going to be SOL when he tries to get the info off the dreamcast.
As it stands, the going rate on BBA's is $120-150 (pre-shipping, pre-tax, pre-hey-we're-all-out-of-em) which could easily replace the dead PC that has got you into this mess.
Even if you find a hidden cache of BBAs at an affordable price, you still are going to have him dependant on NFS mounts and other machines for functionality with the Dreamcast.
My mucking about with dreamcast as a thin-client/mp3-player/SNES-emulator is just that... mucking about. I do not delude myself that I can make it a functioning day-to-day desktop system, and I suggest you re-evaluate your friend's needs with a more cynical eye. I wish you the best of luck in this, and would love to hear how you proceed with said endevour, but you may well find that $250 bucks later the PC is just the best option.
