In the PS/2 days there where suitcase size machines with plasma displays but they only had a single diskette drive that folded out of the front, one model is the 8573-P70.  There where 386 and 486 versions of these machines with microchannel card slots and a SCSI disk.

Ok I was thinking more of the P75, I remember seeing the same 320 or 
400MB disks that where used in early RS/6000 systems in them.  The P70, 
now that I check the documentation the P70, did in fact have an ESDI 
disk with the built in controller, a kind of microchannel IDE disk.
