RQDX3 and Teac FD55

Newer Teac drives are geared exclusively to the PC market. For example, they
only terminate the DS1 (0-3) line, so you pretty much have to use the PC-style
twisted cable. Older drives should work fine. Here's some notes I've written
on using various Teac drives with the RQDX3:

The DEC RX33 is an IBM AT-type drive with some jumper changes. DEC's drive is
some variant of the TEAC FD55G. I have experimented and discovered that the
following drives/jumperings work with the RQDX3:

TEAC FD-55GFV-17-U

	Jumpers in:
	HG
	I (Roman numeral 1)
	U1
	U2
	DC
	FG
	DS0 (for first RX33)
	DS1 (for second RX33)

	Jumpers out:
	(all others)

	Install the terminator, RA1, on the last (or only) drive

TEAC FD-55GFR-540-U

	Jumpers in:
	I (Roman numeral 1)
	U0
	U1
	DC2
	FG
	D0 (for first RX33)
	D1 (for second RX33)

	Jumpers out:
	(all others)

	Install the terminator, RA1, on the last (or only) drive

Toshiba FDD 6882E1J01 (or ND-08DE-G)

	Jumpers in:
	LD
	DC
	DE
	D1 (for first RX33)
	D2 (for second RX33)

	Jumpers out:
	(all others)

	Install the terminator jumper, TM, on the last (or only) drive

TEAC FD-55GFR-149-U can be used as an RX33 by installing jumpers
on FG, DC, I, and D0 (for 1st drive) or D1 (for 2nd drive). The "I" jum-
per is hard to find - here's a picture:

  LG o o
  IS o o o<---- This is the "I" jumper
         o<-/
DC o o o o 
     o o o 

I've tested this with RX50 and RX33 media under XXDP+ and RSTS/E.
