Would all 630QY or 630QZ (microvax II) have RTvax?
The KA630 (MV II CPU) has the usual VAX MMU. AFAIK you need a KA620 CPU:
M7478 KA620 Q RTVAX, 1 Mbyte, FP, TPU clock, boot/diag ROM
(From Megans pdp11-field-guide.txt)
IIRC 630QY or 630QZ referes to a more or less complete QBus machine.
KA620 or KA630 refer to the QBus CPU cards. So you may have a MV II
enclosure that is equipped with a KA620 (RTVAX CPU) instead a KA630 (MV
II CPU). Chek the Mxxxx number on your CPU card.
