I've got an a2000D with 3.1 rom, a SCSI controller (can't remember which but can find out for you), a 2mb ram board expandable to 8mb (can't remember which but can find out for you). It's got WB3.1 installed.
Here is the bad part...

The case is in bad shape, it's missing almost all of the outside screws. That's easy enough to fix, though. They keyboard is missing a key or two but still works just fine. There is also a mouse included, a 2 button "tank" mouse that works the majority of the time. One of the floppy drives is garbage but I do have a replacement and can install it for you. Additionally, it has the old battery on there, which will need to be removed and replaced with a new clip-on battery. I have one of those for you and I'll include it but am apprehensive to install it, I'd rather you find a way for that to get taken care of

Let me know if you're interested. I'll pm also.
