I remember seeing my first RX50 around 1984 or so (probably in a
Rainbow), and its style really did stand out.  It's a shame that
it was all flash and no substance.  At the time, however, 400KB
on a SS floppy was a shock to me - I was storing ~170K on C-64
floppies back then.

As I just posted, it's a Teac FD55GFR with RQDX3-friendly settings for
motor start, etc.  I don't have a filler plate on mine, but the drive
itself mounts to the same sleds as the RX50 or RD5x or TK50, etc.  If
you mean your Qbus PDP-11 isn't in a BA23 or doesn't have an RQDX3,
then I misunderstood.
