Think bigger, now:  16 ports.  High quality external modems.

486DX4/120+MB	$200
SMC Ethernet	$100
Case/PS/Floppy	$100
8MB RAM		$250
BocaBoard2016	$230
16xMotorola28.8	$3680
		-----
		$4560

Even with a disk, this would be quite inexpensive for a fully provisioned 
terminal server.

To compare pricewise to a 10-port Livingston Portmaster 2 (list $2,495),
I can put together a high performance FreeBSD box with a disk ($200) for
$1080.  Add another 8MB of RAM and I'm at $1330, about half the price of the
Livingston and I have 60% more ports.

To compare pricewise to a 30-port Livingston Portmaster 2E-30 (list $3,750)
I could build two of my above boxes, for $2660, have two MORE ports than the
Livingston, and still have $5 in beer money for 218 days left over.

And remember if you're on a budget, you CUT CORNERS!  See if you can get
your cousin's old 486DX2/66 MB for $50.  Convince him he needs a Pentium.
Use an NE-2000 card, $35.  Get a dirt cheap case ($30) and to hell with the
floppy.  Stick at 8MB of used RAM ($200) and run diskless.  Now the box 
only costs $545 instead of $1330.

We're still wayyyyyyyy ahead of the bang-for-buck curve.

AND the whole thing is totally programmable.

FreeBSD's been blowing my socks off for a long time.  ;-)
