OK.  Here I asked what I thought was a fairly innocent question about
a device I hadn't heard about, namely, the C30D.  Evan comes back
with a bit of humor about it being 'a successor to the HP3000 CX.'
Now, I've been around 3000's long enough - going back to the CX, as
a matter of fact - that I got a good chuckle out of that.  Fortunately,
Jeff Kell came through with the correct, or at least more believable
answer of a low-end 5000-series printer.  The only problem I have
with that answer, is that I thought all the 5000-series were labeled
as /135 or /150, etc. to indicate ppm.
