KDJ11-B in a PDP-11/23 backplane?

[David Betz]

Thanks everyone for your advice on using a KDJ11-B in a PDP-11/23. 
Unfortunately, I lost (by a mile!) the eBay auction where I was bidding 
on the KDJ11-B so I guess I won't be doing this upgrade anytime soon. 
Would it be better to look for a KDJ11-A instead? I assume that would 
work as-is with my backplane. Would I need a new bootstrap though? I'm 
currently using a MXV11 (M8047-CA) to boot an RX02 drive. Will that 
work with the KDJ11-A CPU?
