I'm about 99.9% sure that the 4000A is an ST506 to SCSI adapter (I
have one in my ISI driving a couple of CDC Wren II's (ST-506).  I
know the 4070A is an RLL to SCSI, but I forget the ESDI to SCSI board.

Also note that Adaptec has a newer generation of these boards (the
5000 series?), and they might be worth checking out.  The 4000 stuff
came out in '84, I think.

You can get the Adaptec manual by sending $5 to:

		Adaptec, Inc.
		attn: JG
		691 Milpitas Blvd.
		Milpitas, CA 95035
		+1 408 945 8600 x2739 (for literature)

Or, at least you could a year or so ago.  You mileage may vary.
