Here's an interesting tid-bit. I just got off the phone with the AT&T corporate archives, where I had hoped to find schematics and internals documentation for the AT&T 3B2. They do have it, but unfortunately they will not give access to any of it because they still consider the 3B2 to be proprietary information.
I'm disappointed, obviously, but not all that surprised. 25 years is not a long time for a company like AT&T, and I understand the 5ESS system still runs a 3B20 emualtor. They may even still have support contracts for 3B2 installations, I'm not sure. Anyway, all that aside, will soon have access to a couple of 3B2/310s, so I hope to continue reverse engineering the hardware directly. -Seth -- Seth Morabito w...@loomcom.com
