I was recently approached for some suggestions regarding the design
of a simple data logger.  Since I don't have much experience with
this problem I thought I'd see if anyone on the net could provide
some guidance.
 
The data logger is needed as a buffer between an A/D converter and
the IBM PC expansion bus.  The A/D will produce 2k of data at a
high speed (I don't know how fast, but apparently it is not feasible
to use the PC to capture the data directly).
 
Can anyone suggest some sources for a circuit that will grab the
data coming out of the A/D and allow the PC to fetch it at its own
speed? I is there a high speed data logger / buffer IC out there that will 
make life simple?
 
Thanks,
 
Jeff Dickson
