Unknown motherboard

[EX5707]

Silly question of the day - does anyone recognize this motherboard?
The silkscreen shows Tandy 1983, and it sort of looks like its from a Model II, but I don't think it is.

Looks to be a Tandy 2000. I've been working on one lately. I'd take a picture of it, but it requires a lot of disassembly The RAM modules and front-facing keyboard connector give it away.

It's an interesting machine. 80186 CPU. MS-DOS compatible, but not 100% IBM Compatible. Uses 720k 5.25" floppies. Proprietary BUS. It's one odd duck from top to bottom.
