  It's quite possible you saw my Wangtek SCSI FAQ. I'll attach it to the
end of this message. However, you don't say which model of 5099 you have -
it comes in EN (QIC-36), EQ (QIC-02) and ES (SCSI) and possibly some OEM
variations. Unless it's an ES, it's not SCSI. There were very few 5099ES
drives made, compared to 5099EN's and 5150ES's.

  First, the disclaimer: This is not an official representation of Wangtek
or of my employer. This is info I've discovered by reading publicly avail-
able reference material. When changing jumpers, always observe proper anti-
static precautions and be sure you have the current configuration written
down so you have a known starting point.

  Ok. Here's the complete scoop on Wangtek 5150ES drives:

  The current part number for a "generic" 5150ES is:

  33685-201 (black faceplate)
  33685-202 (beige faceplate)

  These are referred to as the "ACA version" of the drive.

  There are _many_ other part numbers for 5150ES drives. If you have one that
isn't one of the above, it doesn't mean you have an old or an out of rev drive,
it just means its a special version created for a distributor or OEM, or with
different default jumper settings.

  You can order the Wangtek 5150ES OEM Manual from Wangtek. It is part number
63045-001 Revision D. Wangtek can be reached at:

  Firmware - There are many flavors of firmware. I have seen the following
parts:

  24115-xxx
  24144-xxx
  21158-xxx

  the -xxx suffix changes as the firmware is updated. According to the folks
I spoke to at Wangtek, the standard firmware is the 21158. The latest version
as of this writing is 21158-007. All of these will work with the Adaptec and
GTAK.

  The firmware options (as returned by a SCSI Identify) are on the end of the
product string, which is "WANGTEK 5150ES SCSI ES41C560 AFD QFA STD" for the
21158-007 firmware. The 3-letter codes have the following meaning:

  AFD - Automatic Format Detection - the drive will recognize the format (such
    as QIC-24, QIC-120, or QIC-150) that the tape was written in.

  QFA - Quick File Access - the ability to rapidly locate a tape block, and
    to implement the "position to block" and "report block" SCSI commands.
    This is compatible with the Tandberg implementation.

  STD - Standard feature set.

  I hope you find this information useful.
