For mass storage it had a LINCtape dual unit (see LINC).

To speed up the calculations it had a separate floating point unit that interfaced like any other peripheral.

With extended hardware it became a multiuser system running MUMPS.Latter additions included an 8" floppy disk and hard disk of larger capacity.The PC12 initially controlled the Artronix brain scanner (computed axial tomography), but this was for prototyping.The PC12 was also the core of an ultrasound system and a gamma camera system.
