Two very generous list members were able to dump ROMs for me -- they came from a 310 and a 400, respectively. The only difference between the 310 and 400 ROMs appears to be the ROM serial number, which is encoded as a struct at the top of ROM. Otherwise they're identical. I sent them to Al Kossow, so I think the ROM images are probably on Bitsavers now (or will be soon), but I've also create a GitHub project for them because I wanted to disassemble and study the ROM contents. That's here: https://github.com/sethm/3b2_rom The only WE32100 tools I could find were written in pre-ANSI C and proved very tedious and difficult to port, so I decided to write my own very crappy WE32100 disassembler instead. I think it was faster than trying to get the AT&T tools to compile on my mac! Still, that means there may well be errors in the disassembly, so keep that in mind. None of these ROMs match your numbers, the ones I have are AAYYC, AAYYD, AAYYE, and AAYYF. These may work for you, it's worth a shot if you have some D2764A's lying around. -Seth
