Thank you
I'm familiar with the Corona Data one; I bought one used for $500 when 
Laserjets were >$2K, and used it as my primary printer for years.
I knew that the board that originally came with it is not very useful, but 
there are other ways to drive it.  I had an ABC DC37 switch for several 
such boards, including the Eiconscript with HP-PCL and Postscript 

But, I didn't know that there was a popular Perq interface.
THAT makes it much more worthwhile!

IIRC, at one time TallTree (JLaser) sold a cheap reverisble modification 
for using LaserJet as a CX-VDO, and a similar interface for SX.

Printer-Works used to provide a lot of information about them.
