So, in a recent pile-o-stuff, I acquired this SCSI
box. The box itself is a
generic two bay SCSI enclosure, but inside is mounted some kind of bus
interface devices. It's a single circuit board, on a frame that mounts in a
half height 5 1/4" bay. The face has a little two line LCD, and some buttons
and lights. The board itself is made by CMD. Seems to be model CSB-2200/SDS.
The board has what appears to be a SCSI input, and two SCSI outputs. The board
contains three NCR 53C90B SCSI chips. Powering the device up, it announces
itself as SCEA/S on the LCD.
It looks familiar. I've usually come across them in 9 bay chassis, with a
SCSI in and 8 devices (0-7) in the chassis, I'm pretty sure that it is a
Raid controller that presents a single drive on the main SCSI channel.
