Hi Denis,

Yes, Eboni-6 should be able to be run in the 1800.

In fact, I've tested both on the 1800.  Avoid Carbon-6 on the 1800.  
The 1.5 pl dot may require a stronger surfactant than Photo-Flo.  
Eboni-6 was relatively smooth on the one-jet test with the 1800, but 
Carbon-6 showed micro-banding.

Yes, the 1800 uses the most available carts.  A certain percentage 
leak at the outlet on refilling, and they should be discarded, but 
the 1800 type carts do seem to be the most abundant standard cart.

> Would be nice to be able to use the R1800 until it dies... ;-)

Yes.  That was my plan.  But the 1.5 pl Eboni-6 is a bit warmer on 
1.5 pl printers than on the 3 pl models.  Expect the most neutral Lab 
B to hit about 2.  That's just barely warmer, but noticeable to me, 
and I tend to favor the cooler tones.

See the C88 graphs for approximate tones on the 1800.

I'm not sure how many Eboni-6 channels would be needed for extreme 
smoothness.
