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.

Mini Computer Products:

but still orderable (I think).

3B20 - Few commercial sites. Primarily AT&T and RBOC internal use. Older
technology. Was being built and used by AT&T prior to divstiture.
3B4000 - Multi-CPU version of 3B15. Had 3B2/600's as communication front
ends. High speed bus to connect all CPUs. First commercial "BIG"
machine.
StarServer FT - Built by Tandem. Fault Tolerant UNIX. Yank a CPU, a drive and
a memory card and it keeps going and going and going....
System 7000 - AT&T Version of Pyramid MIS Server. 3 Models, up to 12 CPUs.
Biggest, hottest offering by AT&T. AT&T & Pyramid are co-developing
enhancements to this machine. 1000 users.
