Fixed my pdt11/150

They were interesting little devices. Apparently someone ported 
Multiplan or Visicalc to one but Dec shot the project down. They were 
essentially a turnkey personal computer in the late 1970's but DEC was 
afraid they would cut into the sales of their minicomputers.

So it was sold as a branch office terminal connector. You could boot 
RT11 and poll 4 terminals and a printer, sending the data over a sync 
serial modem port to the home office. Sad.

Fortunately Dec wouldn't make the same mistake with the Professional 
systems. Oh wait, they did, no wonder they went out of business....
