Maybe for you, but not for me: I like to experiment, have some data collection cards goin' in unison, have a coprocessor doing some crunching. >Any analog-digital converter SHOULD be designed to plug into a DMA, SCSI >or some other fast port.

Seems to me I've seen a lot of VME-based computers. SCSI-basid things would be okay, until you have more than seven. DMA is great too, but after a few daisy-chains, how do ya' do it? (Don't know how things are accessed using DMA.) >I bet that those card slots in the IBMs aren't much faster if they are at >all). Cards in the PC that don't do DMA are clocked at 8MHz on the AT. -- David L.
