	Greetings. Only if you use a few square meters of sand paper :-) 
	(The typical 9-pin (DB-9) is a _bit_ big).

	What I did was take some gold (when you are debugging an 
	intermittent problem, it's nice to know the connector is not it :-)
	connectors, put them on the HP48sx pins, put tape around them as
	to seal their spacing (put one sticky side from below and one from
	above - with the pins in the middle). Then I used some epoxy to
	"cast" a little connector from. After a little sandpaper-ing, I had
	a connector I'm proud of ;-)

	Take care.

	P.S. Nope, but I'm still determined to get my ROMs swapped!
	Even if it's almost over (swap period). Darn, 2 days left.
	(I have rev A and I want rev E)
