I still freakin' love the Tandy 2000 because it was an absolute beast compared to most of the competition at the time—a true workstation class machine at an affordable price for 1983. Yes, it was doomed to fail in the coming PC-clone onslaught. So were a lot of machines.

What did it use for expansion slots? I've seen pictures of the motherboard, but can't really identify what goes where. I don't see any 8-bit ISA slots (which makes sense, as it has a 16-bit bus), and I don't see 16-bit ISA slots (which makes sense because IBM didn't invent that standard until a year later! Also 16-bit ISA would have too many address lines for this thing.)
