<I could have sworn the UK field servoids carried a normal 99MP kit with <the Bristol Spline keys. No idea why as I've _never_ found such a screw <in a DEC machine (although didn't the PDP1 have a Friden Flexowriter as <the console ;-)). No it didn't have splines in the kit. The only recent product that required them was the LN01 xerographic printer, that used a bunch of different keys. Allison
