Odd, I get paid lots of money to support the software (13 of us do) and others get paid to support the hardware. You did buy a support contract, didn't you? Our management would be interested in hearing about cases where your field engineers couldn't fix the problem. The hardware, while suitable for a phone switch, is pretty lousy. Good for what it was designed to do. It's really fast on I/O. Kinda slow for cpu bound stuff. 80 users isn't bad. The Ethernet interface doesn't work at all despite the $$$ I spent on it. Must be your hardware. I use TCP/IP all the time. A 3B20A is our major netnews and uucp gateway. We share the news via rlogin or RFS. The CE's are constantly grousing about having to lug these Delco batteries around and despite that the machine goes wierd everytime the power gets shut off anyway. Power off? Ours gets shut off only when Commonwealth Edison has a thunder storm and drops power totally. The later processors in the 3B line actually claim to be UNIX machines and fare a little better. Much, much better. The 3B2/700 screams but it still isn't quite as good at I/O especially terminal I/O. But the cpu is definitely much faster about 5xVAX or so. -Ron You could go back to good old PDP-11/70's Ron. The RP06's were real toasty during the cold winters. Seriously, you need to talk with the support managers as the 3B20 isn't such a bad box. Put 16 Meg of memory and System V 3.1 on it and life is bearable. Personally, I use it and my own private 3B2/400. -- =Dennis L. Mumaugh Lisle, IL ...!{att,lll-crg}!cuuxb!dlm OR cuuxb!dlm@arpa.att.com
