Here's the whole product line, with a few comments:

7300 - Motorola based UNIX PC oem'ed from Convergent Technologies. Discontinued
       some time ago and considered a failure by AT&T. Large and loyal cult
       following.

UNIX PC - Same as 7300. (Note: Labelling on machines was actually changed
      mid-way through product life).

3B1 (3b1)- An upgraded version of the 7300/UNIX PC. Spotted by the "bubble"
     over the disk drive bay.  Had 40 or 68 MB HDU and more ram.  Intended to
     be a small multi-user platform, hence the "3b" name to move it out of the
     PC genre.

6300 - Original 8086 Olivetti Manufactured MS DOS PC.
6300 Plus - 80286 UNIX/DOS Olivetti built box. Non-AT architecture and memory
     map.  Cult following. First simultaneous UNIX/DOS implementation.

6310 - 8MHZ 80286 AT Clone. AT&T Video (640X400).  Olivetti
6312 - 12 Mhz 80286 AT Clone. Removable Video (Use your own card). Olivetti
6286WGS - 12 Mhz 80286 Olivetti. Small footprint. CPU on a card. (WGS=Work
       Group System)
6386WGS - 80386 Olivetti. 16 & 20 Mhz models. BIG BIG footprint.
6300 WGS - Updated 6300. 1.44 drives, VGA, 10Mhz 8086, 101 Key Keyboard, etc.

       ends.  High speed bus to connect all CPUs. First commercial "BIG"
