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

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.
