There's a nice looking HP 98155A keyboard up on Ebay for a buy-it-now price of $29.99 (though pretty hefty shipping). This is the keyboard that interfaces with the HP 9915 and is seldom seen. I'd snag it but I already have one. http://www.ebay.com/itm/HP-Hewlett-Packard-98155A-Keyboard-Vintage-HP98155A… Grab it while you can. Wayne Smith
