|   The only AT&T "minicomputers" I know of are the 3B family.  As John says,
| the PCs are considered "microcomputers" (do the PCs use 68000 chips?).  The
| 3B family includes the 3B2, 3B5, 3B15, 3B4000, 3B20 Simplex, and 3B20 Duplex.
| I know for sure that all the 3B2, 3B15, and 3B4000 computers use the AT&T -
| designed and manufactured full 32-bit microprocessor.

That is true for the Central Control (CC) for each of those machines.
The 3B5/3B15/3B4000 line of computers also uses microprocessor-based
intelligent peripheral controllers.  The Intelligent Disk File
Controller (IDFC) board does use a 68000 as its engine.  Other
intelligent boards (eg: ITC, ATC, IOA), use the WE32000 series of
microprocessors (32000, 32100, 32200).
