I got lucky with a little trial & error. Setting the MSB of the SR (i.e.
7000) causes AJRLIA to report an error but then keep testing.
Not sure if this works for all the AJ**** diagnostics but hopefully DEC
had some kind of pseudo-standard for this...

Nit picking: The MSB would be 4000. :-)
But yes, DEC often did use similar bits for similar purposes in different diagnostics, especially if they are for the same device. So there is a fair chance that you'll get the same effect from other diagnostics with the same switch register settings.
