Would have thought the hardware was adaptable (Score 1)

I took a look at the schematics for this box http://open.neurostechnology.com/files/r3_rev-b_2006-07-02-0713-1.pdf and realise that this isn't what I would consider "open source hardware". These are all asic's and the hardware itself is not really adaptable (as far as I can see). It's a shame they didnt put down a decent low-cost FPGA, like a Spartan 3aDSP. Then the user would have been able to adapt the hardware, adding video acceleration, custom coprocessors etc. THEN it could have been open source hardware.
