I found EK-KDJ1A-UG-001 "KDJ11-A CPU Module User's Guide,"
which might help, because unless my memory fails me, the KDJ
= 11/73.
I didn't immediately find power-up codes in it -- probably
because something like MXV11-B2 or other ROM set issues the
codes.
If I can find an MXV11 doc, I'll post a message. I used to
have one.
Contact me if you want the KDJ11 manual.
