Take a look on ftp://ftp.avanthar.com/dan/viking_scsi and you will
find the documentation. Warning, it really helps to have a bulkhead
panel that allows you to plug in a serial terminal.
The boards can be configured as Disk, Tape, Disk & Tape, or Disk &
PDP-11 boot depending on the PAL's installed. You need fairly new
firmware for them to work with a CD-ROM drive. They're pretty picky
about what CD-ROM drives they'll work with, but I've had good luck
with Plextor Caddy drives.
