  Err, no skins. The BA23 came out of a rack, so the front bezel is all
there is. I _do_ have a set of skins, but the PDP-11/53 is wearing
them, and I'm not inclined to evict it. :) Probably if I turned the VAX
so the fans face the wall instead of me, it would help, too.
  When somebody donates a SCSI adapter to my collection, I'll be
divesting all the MFM drives myself. I'm not holding my breath.

  Pretty much my guess, too. The disk has half of NetBSD on it (the
/usr/ tree is on a disk I don't have), but it boots far enough that I'm
reasonably certain it's actually got all the RAM the system reports.
