Yeah, the 4MV uses an i960. FWIW wrt to the earlier models, The
Printer Works based in Hayward CA sold HP printer parts, including
I/II/III items,  and had a nice online catalog with lots of diagrams,
photos, etc.  Last visible in Stockton ca. 2018. Waybacking
printerworks.com can be useful:

Looks like they may be defunct now, but maybe carrying on under another
name/new management? Or if not, someone else, hopefully, may have bought
the inventory. Still a number of places selling parts for these,
anyway.
