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
