Early Unix micros; AT&T 3B5

This mention of the Lisa, M20, Onyx, etc. running some flavor of Unix around 1982-84 and my memories of the Hated Plexus reminds me of an experience that I had about that time (i.e. right about the time of the Ma Bell breakup). I'd read in one of the trade rags about the AT&T 3B5 and thought it would make a great development machine. To this day, I don't know if my hunch was right or not. I called AT&T computer sales and got the runaround for at least a week. Fortunately, most of the referrals I was given were 800 toll-free ones. I never could find someone who could sell me one. It seems that everyone thought I was talking about the 6300. It was very frustrating--"We have dollars; we like trade them for computer. Don't want 6300; want 3B5. Ugh" Did anyone on this list ever succeed in acquiring one around that time? If so, how was the service and performance? Cheers, Chuck
