I support equipment in the industrial sector. We have a few of the Vax QBUS consoles left in production that are from the late 80's to early 90's. They use 46 MB MFM hard drives and to load them 5 1/4" floppies are used. The console support 4 heads via RGB video and serial cables for the keyboard. No mouse on this thing. Some of the units support touch screen through an XY IR interface but those were rare since they were very finicky. The console has removable boards that allow for different combo's of CPU, Memory, Video, and disk controllers. The consoles are surprisingly robust with the exception of the hard drives which have a very high failure rate.
