Yes, I got these, but sold them after being contacted by someone that
needed them. They were a 2 or 3U rackmount, so basically they're the
samme size as a BA23. Nice enough systems, but a bit of a pain as
the disk and I/O was all proprietary SMS off of the Q-Bus. Since
they used MFM HD's they're not something I'd really recommend.
