And my parallel port Iomega ZIP drive, it seems. I actually checked
earlier and although it doesn't use DMA (it says it's using "EPP
32-bit") it does use bidrectional communication; it's an sd device.
I admit most of those will be confined to history as well with respect
to actual use (they existed with 100MB, 250 and 750MB disks, although
the 750 one probably not as parallel) but they looked cool, so people
haven't just thrown them away yet :)
