I hate to say it, but that's before my time other than tinkering with the
CPU bus sticking out the back of an old Amstrad CPC... There are various
things now bringing high end commodity CPUs (as opposed to specialist DSP
hardware) and FPGAs close together - offerings from Cray, SGI, this new
opteron socketed thingie etc. Most of the fuss is around their use in
reconfigurable computing so the offerings tend to be lacking for raw
serial IO...

: Whats you acquisition area?

Starlight - astronomical adaptive optics. Potentially you can be talking
about multiple CCDs of many thosands of pixels framing at over 1KHz...
