There are one or two bits in a register of the RK11 that have a different
meaning/function, depending on the controller being a -C or -D. 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?)
I did not know that. If someone can point me to the description of the differences I
should be able to say what RSTS will do with them. Did you specify overlapped seek in SYSGEN?
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.
