The RK11-C was quickly replaced by the RK11-D, but I guess RSTS would know the difference. Other guys here will be able to give a lot better light on this than me (Paul?)

Oh, I didn’t know that either!

Yes, I did enable overlapped seek during SYSGEN, and I did just have some trouble with overlapped seeks on my RK11-C (though I repaired that well enough to pass the associated MAINDEC before trying RSTS).

I’ll try a non-overlap SYSGEN soon/next -- right now it takes me a little over two hours to image a pack using PDP11GUI and a DL11 at 9600 baud, which is a bit painful.  So I’d like to capture some logic analyzer traces off the RK11-C while I have this repro case before I write over my current pack.  If there is something still up with my overlapped seeks, I’d like to characterize and fix it anyway.
