Keyboard part # for HP2648A?

Wow... 3 of 'em :-). How often do you fire them up? They used to have some of these in the terminal room at udel.edu and were the first raster graphics terminals I remember seeing, around 1980. I'm trying to secure my first unit from Boise -- I'll probably be able to pick it up next weekend. I got the user manual from bitsavers and I was surprised to see how many options it had, with a "main frame" and all that. Besides the dual tape drive option, do you have any other options on them? Recently some ROMs were offered on ebay but god knows what they actually provided (presumably they provided additional graphical character sets or something like that). -- "The Direct3D Graphics Pipeline"-- code samples, sample chapter, FAQ: <http://www.xmission.com/~legalize/book/> Pilgrimage: Utah's annual demoparty <http://pilgrimage.scene.org>
