I wouldn't sell the A630 board if I were you. You could construct a (my) dream A600 with it. Put a 4-way ide adaptor, internal ide laptop cdrom, ide compact flash drive, pcmcia wireless or standard lan card, external flicker fixer on the 23-pin 23 port and a nice svga monitor (recommend a Sony Trinitron). With 3.1 ROMs, a 68030, 32MB fast, 2MB (including trapdoor), you can do anything on the net with the a600 all in the original case. It's the equivalent of a similar spec'd A2000/3000 with a much smaller footprint. Check out those A600 upgrade sites (seeing is believing).
btw, the ribbon cable for the a600 keyboard is a bit narrower than the A1200. I know because I tried (anyone have a spare a600 keyboard?).
