Do take a look at D-TACQ ACQ196CPCI : 96 simultaneous differential channels, 16 bit resolution, one slot.
http://www.d-tacq.com/acq196cpci.shtml
The card runs Linux, has Ethernet connectivity and runs an EPICS IOC on board.
So a single card in its own private 1U chassis could meet your requirement.
Regarding your specific application, we have a burst streaming mode that will support rapid short bursts;
The EPICS IOC doesn't support this mode at the moment, but it isn't a million miles away either.
Best regards
Peter.

EPICS colleagues:
The LLNL group that is supplying the diagnostics to commission the LCLS needs a digitizer for an energy measurement instrument (calorimeter) with the following characteristics:
- 100 channels sampled simultaneously - each channel takes 100 samples at 10us per sample (1 ms total time) - differential inputs - 12 bits minimum; 14 or even 16 bits preferred - sampling repeats at 120 Hz major cycle with trigger
A VME or VXI format is ideal.
Any suggestions are most welcome. Ideally, we can discuss this in depth at the June meeting.
