And in 1978 DEC came out with a baby version called the KS10. This 
system had MUCH less performance than the KL10 and was much smaller. 
It would run TOPS-10, TOPS-20, or ITS. It used an 8080 as the 
front-end instead of the PDP-11/40. Same deal as the KL10, swap the 
pack and hit the boot button. This one is in my cellar:
