        Ahh, the 'WorldBox.' Nice enclosure! It's the only one I've seen that can
be both a server and an end table in one package. ;-)

        With the other two memory boards present, this is correct. Max memory for
the MV-II was 16MB. Still plenty for VMS or NetBSD.

        Yes. These would be 8MB each.

        You're in luck. The 7516 is a DELQA, the later of the two.

        This is an RQDX3. It can handle up to two hard drives (the RD54's are 170
meg or so) and one dual floppy drive.

        Some MV owners (myself included) have pulled away from the RQDX3 for hard
drive support, and turned instead to ESDI or SCSI drives using the
appropriate board from Dilog, Emulex, or whoever.

>M7546 Tapecontroller for TK50

        Specifically, a TQK50 controller.

        Oooooh! Lucky person!! That's an early Dilog Qbus to SCSI adapter!

        I suspect this is correct, but I don't know for sure. The 703 may be
tape-only, while its big brother, the SQ706, should be able to do tape or
disk... can someone who's Dilog-fluent check me on that, please?

        No. You'd need either an "official" DEC console cable, or you can make one
with the pinout chart from:

        Good luck! The MVII is a nice system, and (if you like Unix) will run
NetBSD (www.netbsd.org) no problem.
