Hey folks,
I've started down the path of implementing an AT&T 3B2 simulator using the SIMH platform. Key to doing this will be access to 3B2 ROMs and technical information, both of which have proven very difficult to get ahold of.
Right now I'm working from the 3B2 information publicly available on Bitsavers and Unixwiz.net, plus I have remote Telnet access to a 3B2/600 so I can use the compiler, assembler and disassembler tools on a running platform. I've also been reading through the AT&T SYSVR3 source code purloined from anonymous sources, and the GPL'ed AT&T 5620 cross-development tools (it's not a 3B2, but it does use the same WE32100 CPU).
If anyone has AT&T technical documents that might be useful, or can provide dumps of 3B2 ROMs, please do let me know! I'm open to just about any model of 3B2 right now, whatever I can get my hands on.
