Hi Alan,
Nice to see you on the list. If memory serves me correctly, you presented
a talk on (very) high speed data acquisition at DECUS a few decades ago. > DEC RKV11D Q-Bus controller for RK05 disks (on my
LSI-11/73 system)

Cool. Is that mod documented (on-line, that is... not just on some
35-year-old paper)? I have an RKV11D that I've used under RT-11 with
16-bit memory... love to put it on a larger machine.
Good luck on posting your stuff. I'm far away so I'm not likely to be
interested in anything huge and heavy, but I'll take a peek.
Cheers,
