Found what looks like a floppy/hard disk controller.
A full-size board with lots of surface-mount devices.
Silk screen says:

		FAB0005349 REV D
	SMS	SMS MODEL OMTI 8    520
		ASSEMBLY 000 6347-0001   REV K

The location of the headers seems to indicates that it's a
floppy/hard disk controller, but the ole "plug it in" test failed.

The landmark chips are:

	FDC765A / SMC 8721
	Z8
	SMS / OMTI 20505C / NCR 0380746 / ...
	SMS / OMTI 20506C-32 / NCR-0380668 PT / ...
	SMS / OMTI 20508C / NCR-0380780 / ...
	... and a few others

There are numerous headers with some shorting blocks in place.
A 20pin header near the rear of the board, labeled W14 - W23.
With jumpers across W14 pair, W15 pair, W20 pair, W21 pair and W23 pair.
	
An empty 16pin header at mid-board, labeled W4 through W11.

And an empty 4pin header near silk screen at front of board, labeled J1.

And of course the 2 20pin and 2 34pin headers for cables at mid-board.


Any clues?  A phone number, address or e-mail address of SMS
would be nice, or if anyone actually is familiar with this board,
some first-hand advice would be terrific.

Thanks,
