Here are the results:

Before - the CSR, VEC were set as follows

VIKING MSCP Disk controller : CSR 772150 VEC 154
RQDX2 MSCP Disk controller : CSR 760334 VEC 300
DHV11 Serial Mux :                   CSR 760460 VEC 300
TQK50 TMSCP controller :        CSR 774500 VEC 260

After -

  $ run sys$system:sysgen

SYSGEN>  CONFIG
DEVICE> uda,2
DEVICE> tu81
DEVICE> dhv11
DEVICE>^Z

Device: UDA     Name: PUA       CSR: 772150       Vector: 154 Support: yes
Device: TU81     Name: PTA       CSR: 774500       Vector: 260     
Support: yes
Device: UDA     Name: PUB       CSR: 760334*      Vector: 300* Support: yes
Device: DHV11     Name: TXA       CSR: 760500*      Vector: 310*     
Support: yes

SYSGEN>  EXIT

After changing the CSR and VEC of the DHV11 and rebooting :

The TK50 still does not show up, I think it is because the tape drive is 
not functioning (can't move the lever to allow a tape to be loaded).
However, I do have functional RX50 floppys, just need some media.  I 
have a couple spare TK50's and will try those to see what happens.
