It should go without saying that the 3B2, even with all its horrible flaws, is pretty special to my heart, given all the effort I put into emulating it! I've learned to really like the WE32000 architecture. It's just so well suited for UNIX and C. It's a pity the clock speed was so slow, and that the 3B2/310 and 3B2/400 were so limited in memory. A 4MB maximum was not a lot for a serious multi-user machine, even for 1985. But, I have absolutely no experience with the 3B5 and 3B20. I would love to hear more about them from those of you with experience. Were they ever a marketing success? (And here, by marketing success, I mean as a general purpose UNIX computer, not as a telephone switch) Emulating a 3B5 or 3B20 would be fun, but I've seen even less internals documentation about them than I have about the 3B2, so I fear it's a hopeless task. -Seth -- Seth Morabito https://loomcom.com/ web@loomcom.com From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: tuhs-bounces@minnie.tuhs.org X-Spam-Checker-Version: SpamAssassin 3.4.1 (2015-04-28) on inbox.vuxu.org X-Spam-Level: X-Spam-Status: No, score=-0.8 required=5.0 tests=HEADER_FROM_DIFFERENT_DOMAINS, MAILING_LIST_MULTI,RCVD_IN_DNSWL_NONE autolearn=ham autolearn_force=no version=3.4.1 Received: from minnie.tuhs.org (minnie.tuhs.org [45.79.103.53]) by inbox.vuxu.org (OpenSMTPD) with ESMTP id 9354e64a for ; Fri, 29 Jun 2018 16:29:22 +0000 (UTC) Received: by minnie.tuhs.org (Postfix, from userid 112) id 8FFD3A1B3C; Sat, 30 Jun 2018 02:29:21 +1000 (AEST) Received: from minnie.tuhs.org (localhost [127.0.0.1]) by minnie.tuhs.org (Postfix) with ESMTP id 94007A1849; Sat, 30 Jun 2018 02:29:16 +1000 (AEST) Received: by minnie.tuhs.org (Postfix, from userid 112) id 46DEAA1849; Sat, 30 Jun 2018 02:29:15 +1000 (AEST) Received: from smtp-out-2.mxes.net (smtp-out-2.mxes.net [67.222.241.118]) by minnie.tuhs.org (Postfix) with ESMTPS id EDA48A1815 for ; Sat, 30 Jun 2018 02:29:14 +1000 (AEST) Received: from mua (mua.mxes.net [10.0.0.1]) (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)) (No client certificate requested) by smtp.mxes.net (Postfix) with ESMTPSA id A7620275C7 for ; Fri, 29 Jun 2018 12:29:13 -0400 (EDT) From: To: "'TUHS main list'" References: <00f101d40fab$5af29aa0$10d7cfe0$@ronnatalie.com> <87muvdlilk.fsf@loomcom.com> In-Reply-To: <87muvdlilk.fsf@loomcom.com> Date: Fri, 29 Jun 2018 12:29:13 -0400 Message-ID: <013201d40fc6$5118ad60$f34a0820$@ronnatalie.com> MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit X-Mailer: Microsoft Outlook 16.0 Thread-Index: AQIhTJzfpraWbU/oao24B38Q0q6J/wIlHzA8o8vKDDA= Content-Language: en-us X-Sent-To: Subject: Re: [TUHS] ATT Hardware X-BeenThere: tuhs@minnie.tuhs.org X-Mailman-Version: 2.1.20 Precedence: list List-Id: The Unix Heritage Society mailing list List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: tuhs-bounces@minnie.tuhs.org Sender: "TUHS" My favorite 3B2ism was that the power switch was soft (uncommon then, not so much now).

We had huge numbers of 3B2s at Columbia that were gifted to us by AT&T. They didn't know what to do with the things, so the undergrads were subjected to using them for their labs for a few classes like computer graphics. The blits attached to them were neat, though. If only the same could have been said for the overall system. > The 3B20 was another > thing. It was a work of telephone company art.

It was put into an extra machine room and not used for very much, I think because the version of the OS it came with didn't really do networking at a point where everything else at the Columbia CS department did. At one point we considered reusing its disk pack drives for some of the Vaxes but unfortunately the cabling was incompatible. Perry -- Perry E.
