I admit to getting it, as I didn't want it to really be official until I had it in my grubby hands. Anyway, some preliminary pictures:
Nice condition - looks pretty much unused other than the labels and two missing caps.
Looks like an SIO port of unknown protocol (RS-485 possibly), and something else.
Made by our better and nicer neighbors.
As I suspected (with slightly lesser chance of rubber dome and almost no chance of capbs), it's a membrane type BS. Spacebar is rather interesting though - quite light and smooth, and obviously they improved on the AT's crappiness by using normal stabilizer wire. I can't readily remove it however, as something seems to be holding it attached. Will have to wait for the overall disassembly.. maybe sometime this weekend.
Preliminary thoughts: Interesting curio, and another completely unknown to us IBM board surfaces. My previous one was almost a year ago, but hopefully there are still bizarro boards out there
