    The 2608 and 2610 were two very different animals, unfortunately.  I 
also worked on the 2619, which was a 1000 lpm chain/train printer 
manufactured for HP by Printronix, and the 2617 drum printer.  I don't 
remember a lot of details after 20 years.  :-)  With the HP maintenance 
manual and a scope though, you can do a lot.
