 some way.  I don't recall ever having seen them selling the ISA card +
 video interface card separately, i.e. without the engine. 
 This was a box-stock LJII from another vendor.  The Jlaser was a RAM plus
 laser printer interface card, a big cable (DC37 for CX), and a small
 adapter card that fit in the back of the LJII.  The LJII was still capable
 of switching back and forth between JLASER and "normal" HP
"Centronics"
 PCL transparently under software control, so we had two computers cabled
 to it.  For CX LaserJet "minus" and the like, Talltree sold some sort of
 adapter board (to go IN the printer?) that was switchable between
 JLASER and "normal" LJ HP RS232 PCL.  On CX VDO units, such as Cordata,
 JLASER was a simple DC37 cable to the "video" input. 
   Yes, I remember it.  At least, I think I do! ;)  Is it possible there
was another product that was as I described above, using a modified SX
engine to achieve higher resolution (not the LJ-III style "resolution
enhancement" trick) and sold as a package with ISA interface and
printer?  I'm 100% certain that there was one, but I am NOT 100% certain
that the one I'm remembering was the JLASER.  We never got one of those
at my old company in the late 1980s, but we wanted one for in-house use.
   (My company sold and installed quite a few similar systems, mostly
the one from QMS that used the raw video interface.)
