OK, I have tried >>>B MKAn for values 0->7 and ended with a quick 84 FAIL
in each instance.

Likewise, I have tried >>>B MUAn for the same values with the same
results, excepting n=0. In that instance, I first see the

-MUA0

displayed and sometime later:

%VMB-F-ERR, PC = 00000765
%VMB-I-STS, R0 = 000008C2
 84 FAIL ^^^

In this case, however, ^ this value is different from the other instances.

Likely so, as it is not terminated.

I tried it with the T 50 disconnected and the change was that the
01000001 value became FFFFFF05 also. With it connected but powered down,
I got FFFFFF03 FFFFFFFF FFFFFFFF ...

Right now, I am trying again to boot from the TK50 after setting MUA0 as
default via T 51. I entered just 'B', and it has tried -DUA0, -MUA0, -ESA0,
?54 RETRY, and is now on ESA0 again. I'm not sure how long this will go
on, but it looks like it is skipping MUA0 on this go round. Yes, it is.
It is cycling between -ESA0 and ?54RETRY.

Could the TK50 drive itself be faulty, or d\the tapes themselves?
