 I believe all the boards listed below are the various
varients of the /53
...
 and /53+.  It was commonly used in DECservers 550's
which explains the LAT
...
 ROMs listed on some of them.  One of those can be
converted to a PDP-11/53
...
 by replacing the ROMs with PDP-11/53 ROMs. 

Oh yes there were plenty of variantion of the base "11/53" out there.
Most were
supposed to be J11 powered but like I said many have M8189s.
