Acquired two of these, which seem compete.
Pulls from some time ago badged for system which they were embedded in.
They appear to contain a DMA channel of some sort, but otherwise have hard disk and floppies.
Preliminary survey of boards:
Rear view of one system (top) front of other. Floppy drive is missing flap on one system
