Lines: 19
Keywords: Suggestions: (and I've done/designed several of these expansions)

1. go to the 11/73 (bugs still in the 11/53)
2. if the backplane is not VERY old, string the extra four lines is very
	simple.
3. dump the dlv11-j's since  A. they only do single character i/o
			     B. they are only good at 1200 baud sustained
			     C. they improperly pass bus signals
			     D. generally are disgusting (direct quote from
				a DEC hardware developer)
4. add more memory and a dhv11 (or third party equivalent)

	the above are objective expansions...the 5th suggestions is from a
personal point of view:

5. upgrade to RSX-11M-Plus to take advantage of all the new hardware (i/d space
and supervisor mode.....as well as a MUCH much better terminal driver...)
