I have a question about storing real time data in the IBM ram. What I want to do is interface an A/D converter whose conversions are initiated by an external clock. The "conversion done" line will be used to request a DMA byte transfer from the converter to IBM ram. My question is: Will refresh come in every so often and screw up the timing of my incoming data? This data is real-time so I must keep these samples regularly spaced in time. (Assume my sample rate is slow enough to allow DMA time to finish) How can I avoid this problem if it exists? Eric Cox
