Has two *really* fast DMA channels. It was used alot in embedded
applications where you hade to move a lot of data really fast.
Frequently found on SCSI disk controllers (among other things).

The MAD-186 by MAD computers was a PC 'sorta compatible', I used
to have (it was re-badged by TELEX). It used an 80186.

The 3Com 3Server3 was another computer (well, okay, fileserver)
that ran a modified MS-DOS (2.x, IIRC), had embedded SCSI (actually
SASI), ethernet, and serial/parallel interfaces. It also used
the 80186.
