Re: Star Wars Problem

Saw a strange problem on my Friend Kevs Boardset....  Tie Fighters were starting to stretch and distort a bit like that. Math Box tests were OK, but I read up on the Maths on Jed Margolins site, and decided to go for the divider chips ( might have been multipliers, but I'm fairly certain it was dividers).  That solved the problem. The maths for moving each point about in 3d was flawed due to the fault. Its not deadly accurate anyway, but good enough for a few seconds on the screen and you don't notice small maths errors accumulating and creeping in. Jed explains it quite well. So, basically in this case by reading up 'how it works' we zeroed in straight away without delving too deep into electronic troubleshooting.

AVG chips are notorious for being bad, so i'm thinking that maybe you used one avg chip on two boardsets? that would explain things.. -- Andrew Welburn http://www.andys-arcade.com ----- Original Message ----- From: "Rich Harkoff/Don Roberts" <rharkoff1_at_new.rr.com> To: <vectorlist_at_vectorlist.org> Sent: Wednesday, January 19, 2011 1:29 PM Subject: Re: VECTOR: Star Wars Problem Hi Karl, Both boardsets exhibited the same symptoms so I figured problem was elsewhere. Deflection prob? No hardware or mathbox errors on either boardset, I have access to another set of boards which I will try and get a hold of. I don't notice any jumpiness with the Tie fighters during game play but I do see the scaling. Had some problems getting the vids to play smooth, uploaded them from one of those Flip video cameras.

The Tie fighters, etc look awfully jumpy in the videos you have posted, they are not scaling correctly as they move around the screen. Have you put it into test mode and run the mathbox checks? Cheers Karl.   From: Rich Harkoff/Don Roberts   To: vectorlist_at_vectorlist.org   Sent: Wednesday, January 19, 2011 2:02 AM   Subject: VECTOR: Star Wars Problem   Hello,   My Star Wars game has developed a problem and I was hoping someone here might be able to help diagnose. First off the boardset is fine, swapped it out with a friends and problem still existed. I completely rebuilt the deflection board  this past summer. High Voltage is right on the money. When playing game I see a vertical white stripe on left and right of screen during explosions and death star blow up. On attract screen right after the Star Wars blue logo as the green letters in the story line scroll up the screen the letters appear mashed together at botttom left and right on screen. I took some video showing the problem, the vids are located here:   http://s593.photobucket.com/albums/tt19/don1400/STAR%20WARS%20VID/   Any help would be appreciated.   Thanks,   Rich --------------------------------------------------------------------------- ** Unsubscribe, subscribe, or view the archives at http://www.vectorlist.org ** Please direct other questions, comments, or problems to chris_at_westnet.com
