I cant seem to find any sort of info on this monitor in this machine other than its model? Venturer III?

Its got no vertical deflection and I see a fried resistor at R405, right behind the vertical controls.

:(

I'm wondering if one of you might have this game and could perhaps post the value of the part in question.

Or if schematics exist... please post them.

Thanks!
 
There are 2 chassis for Computer Space.
First you need to identify which one you have.
 
thanks for the pointers guys!

I believe I have the 12SF chassis. I found the value of R405 from a schematic I found somewhere (wish I could remember where now). I also tested the "new" tubes and the one for vert deflection has a short that it shouldn't have. I asked the customer to order a new one and some 2 watt resistors. If I make it back there in a few weeks I will attempt to fix the TV again.

I did manage to fix a Pong and Steeplechase while there so it's not all a loss. lol
