In addition it might be possible to use the floppy-DMA to sample at the speeds required -- and possibly allowing extended samples to hard disk. Quick calculations indicate that it may be technically feasable to use this method to sample 32 bits at 15000hz, 16 bits at 30000hz, or 8 bits at 60000hz. If this proves possible, then the processor would remain available to write the incoming data to the hard drive. Alternatively, it might be possible to build a SCSI sampler, using the hard-drive controller to put the data into memory. ----------->Steve Holland<----------- Internet: wildcat!steve@alphalpha.com| "I never let my schooling get in the USENET: ...!alphalpha!wildcat!steve | way of my education" -Mark Twain
