In my quest for a working RX02 I'm trying to find out the best way of
checking out an RXV21 and get it talking to the RX02. I have most of the
standard diagnostics including XXDP.
The setup is an 11/83 with an RX50 and RD53. (I can boot from either)
In the box is
MSV11-J PMI
KDF11-B
RXV21
RQDX3
They are in the order as above. The two dual height modules are in the
right hand side of the back plane when viewed from the front.
I am unsure as if there is a utility for RXV21 among all the diags I
have or should I go in with ODT on a halted system and look at registers.
With the setup above I need to get the RXV21 going in order to check out
the RX02.
The precise syntax of any commands is important because presuming I may
have prior knowledge is not a good
idea.
I may have known this stuff in the past but I cant remember if I did or
not!!

You did not specify the backplane. I am going to assume
a BA23 box. Since both the RXV21 and the RQDX3
are dual modules, and the first three slots are ABCD,
you do not need (and should not have) a bus grant
(M9047) beside the RXV21. So while the RXV21
is in the AB portion of an ABCD slot, the RQDX3 is
in an ABAB or Q22 slot. That is what is supposed to
be the situation. If you add a TK50, then that controller
will be placed into the 4th slot beside the RQDX3.
As long as the RQDX3 is immediately below the RXV21
and the RQDX3 is working, then you should be able to
check the IOPAGE registers on the RXV21 while you
are running RT-11. Either use ODT or SD.SYS if you
are running V05.05 of RT-11 or later.
Other than that, I can't help much with the RX02 drive.
The only thing that I can think of is that the cable between
the RXV21 and the RX02 is installed incorrectly. I seem
the remember doing that once or twice.
Other hardware individuals can help much better that I can.

Thanks for the reply.
Its good to know I have at least got the boards in the right order.
Well we have moved on again after a complete check of cables and
connectors.
The DY (RX02) driver seems to have loaded and now the RX02 has started
to respond.
If you do say DIR DY0 then drive 0 clonks even if there is a disk in the
drive.
Same applies for drive 1.
So drive select works . Its probably looking for data from the head or
sector pulses.
So me it seems to be down to the drive itself.
It fails with controller error 20 so I best go find what that means
