CDP 1861 Video Processor

I am trying to get a RCA Cosmac VIP up and running, but I have  two problems. 
 I'm not familiar with the connector that this computer uses  for the display 
and don't know how to connect it to a monitor (or whatever type  of display 
it uses).  The second problem is I need to find the 1861  chip.  Does anyone 
know of a source where I can get one of these  chips? 
 
My last issue/question is verifying what type of computer I really  have.  
The box the computer came in is for a 18S711, but then there is a  hand written 
note saying it's actually a 18S022.  How can I verify  that it is indeed a 
18S022?
 
Thanks,
 
Jeff
