Subject: How do I attach an RA81 to a DECsystem 5400?

    I've got a couple of RA81s which used to be used on a now defunct
VAX 8530 which I would like to use.  I've been digging through the manuals
for our 5400 and it appears that I can probably attach these drives; but I
will need a KDA50 controller to do so.  Can somebody tell me if this is
correct and if there is anything else that I need to worry about (the rev of
the KDA50 for example)?  I appear to have a 5400 model 210QS with an
additional expansion chasis with one RF style disk if that matters.  Will I
have any problems with the MSCP implemented by the KDA50 controller versus
that used by the DSSI/RF disk combination?.  Can I put a KDA50 in a 210QS
package?  What should I pay for a used KDA50?

                Thanks,
                Bill Bogstad
