The model 300 system runs around 8 MHz, and the model 310 runs around 10 MHz (I keep forgetting the exact numbers - it might even be 8 and 12 MHz). There might be other, incidental, differences such as hard disk size and basic serial ports configuration. Randy

The major difference between a 300 and a 310 is that the 300 did not use a "regular" cpu chip. It had a daughter board where the cpu should should have been. This board substancially slowed opperation of the system. (I think the buss clock had to run slower to accomidate it, or the logic was too loose, but I don't know for shure) There was an upgrade from the 300 to the 310. If you have a 300, get the upgrade. If you don't have a 300, don't get one! Having gotten a peak at a few price/bundling type of stuff; if you are going to be using networking (etc.) or you are only going to have a couple of users, the 6386 machines are MUCH more cost effective. If you want major disk space, or more users, then the larger numbers in the 3B family will serve you better. A 310/310 is a dead end. Rob. BAN THE SVR3.2.1 LP SUBSYSTEM!!!!!

The first thing is the 3B2/310 is a direct replacement of the 3B2/300. They look exactly the same from a physical perspective. The much more important difference is the CPU on the 300 is an older verion. The 3B2/310 has a WE32100 CPU (That's Western Electric). This is an upgraded version of the earlier model and is running at a faster clock rate ( 10 Mhz ). There is an upgrade available for 300 to allow you to improve to a 3B2/310. I have a converted 3B2/300 as one of my home machines, so the process is quite simple to do. My system is now a 3B2/310 running at the 10 Mhz. You may find it difficult to aquire the upgrade kit in the future, since the 3B2/300 is a discontinued model, so if you have one of there beasties I would recommend upgrading as soon as you can.

Wrong. Yes, all machines with the hybrid chip are model 300s, but many
model 300's were built with the 32100 chip set, after the new design was
proved in. The older hybrid chip was the first full 32-bit CPU on the market
(no internal multiplexing of data paths, etc.). All of the first year or so's
production of model 300's were built with the hybrid chip. When new and better
designs were available, they were implemented to improve the machine.
The model 310 was an improvement over the model 300 primarily in the area of
processor speed. Since the higher processor speed would allow more simultaneous
users, increased disk space would be needed, depending on application, to
accomodate these additional users, so most versions of the 310 have higher
disk capacities, up to a maximum of 72 Megabytes (formatted) from the factory.
The slower speed of the old model 300 hybrid CPU was due to the fact that
that was as fast as it could run.
:There was an upgrade from the 300 to the 310. If you have a 300, get
:the upgrade. If you don't have a 300, don't get one!
BTW: Whether you have an older 190A system module (the one with the hybrid chip)
or the newer ED4C637 board, the upgrade will probably include a new, faster
ED4C637 board with the faster clock speed.

Also, the 3B2/300 is no longer sold by AT&T but the 310 is. Support is the issue I'm driving at. I do believe that AT&T still supports the 300 but it is an important difference. Another important difference is the operating systems. The most current releases of UNIX for the 3B line (3.2.X) will not run on the 300 but they will run on the 310. I believe that the lastest OS release for the 300 will not support SCSI peripherals. All in all, the 3B2/310 is a superior machine (big surprise eh) above and beyond the gain in clock speed. ------------------------------------------------------------------------------ Hans Jespersen UUCP : attcan!{uunet|utgpu}!watmath!trillium!hjespersen University of Waterloo USENET : hjespersen@trillium.waterloo.edu Waterloo, Ontario VOICENET: (519)747-1721 MAILNET : 20 Dunbar St. N, Waterloo, Ont., N2L 2C7 ------------------------------------------------------------------------------

I must apologize for this posting, as some of the information contained within is incorrect. Apparently the most current release of UNIX for the 3B2 (3.2.X) WILL run on the 3B2/300.
