(Re)introducing the P/N 69H8533... and that's all I know about this. Not even a name.

I picked up this numeric keypad from Yahoo! Japan Auction for a very decent price out of curiosity, a purchase made very much in the dark. I'm hoping someone here much more familiar with Japanese IBM gear can tell me more about this thing. My preliminary search found not much other than this could have possibly sidecar'd the IBM 5535-ZAD, a large ThinkPad-looking thing that looks to be a buckling sleeves TrackPoint keyboard (possibly an adaptation of the Model M4-1 or M6-1).

Anyway, my initial impressions are somewhat pleasantly surprised. I think it's got a fairly nice expanded layout, it's very rigid, and the legends have held up well over the years. Whatever domes this thing employs are okay all things considered - decent tactility, not much mush. Nothing exceptional though.

If the switches were mechanical I'm sure you'd like it more (even if they felt the same :P)

It's an interesting layout (back tab could actually be useful). The left column and divisions make it symmetrical, so the 0 key's size and spacing really stand out (in a good way).
