OH, sorry, I got them mixed up, I thought YOU had one 
running there!  Geez, I wouldn't think it would be all that 
hard to get a KA10 running, just a LOT of discrete 
transistors.  A couple guys at Wash U got a Linc running a 
few years ago.  Mostly all they had to do was put new 
capacitors in the power supply.  Of course, I know there's a 
LOT more logic in a KA10.

I'm pretty sure I have heard of some KA10's running, 
somewhere, in the last decade, but that could be apocryphal.
