Title: [de] IBM Numpad 1992
Post by: 2084 on Mon, 08 November 2010, 11:46:28

IBM Numpad (http://cgi.ebay.de/10-er-Tastatur-IBM-PS-2-Anschlus-/320610729373?pt=M%E4use_Tastaturen&hash=item4aa5e37d9d)

This one looks like a good deal for IBM collectors.
The description says there is a feedback when pressing, so I think it's buckling spring.

Very cheap shipping too - ends tomorrow

Looks like M2 keycaps, it is was too low a profile to be a regular buckling spring.

Looks more like M4 to me.

Lowpoly is correct. This was the external numpad of the IBM L40 laptop. IIRC, the weird trackball/mouse doohickey connected into the numpad, and the numpad connected into a general purpose PS/2 port on the laptop. Or you could just connect the mouse to it.

I can vouch for that as the L40 was my first computers and it indeed come bundled with that numpad.
