Hi Guys,

went to power on Star Wars (UR) last night, and got the following errors:

VG RAM 2 AT 3P
VG RAM 4 AT 4M
VG RAM 5 AT 4P
VG ROM AT 1L 52FB

I have attached a picture for reference.
Do I need to replace the AVG board? where can I get one?
Any Star Wars/Atari Vector experts out there?

thanks for your help. :)

I've personally never seen that many errors on an AVG board. Check the basics first. If you have the EMI/RFI board on remove it, check the pin connectors on the boardset. Take a pencil eraser after them and clean them up. Plug the harness DIRECTLY onto the board.

Sorry new to working on Star Wars. EMI/RFI board, what exactly is this?

Plug the harness directly onto the board? sorry, need more info please, really new at working on this game.

thanks.

The SW boardset let's say is really 5 boards. The main 3 are the AVG, Sound, & CPU. The two others are the interconnect and the EMI. The interconnect is the board that sits in the back part of the PCB cage that connects the main 3 together. The EMI is the front board that the wiring harness plugs into.

The EMI board is not needed and can be removed and the harness plugged directly into the connectors where the EMI board connects to the 3 board stack.

sounds like an address/data buffer issue... shouldn't be too hard to sort out.

Hi guys,

thanks for all the helpful advice. well I've tried just about all that was suggested and to no avail.

1) checked the EMI/RFI connectors and cleaned them off with a pencil eraser.
2) attempted to plug in the wiring harness directly onto the board.
3) reseated the chips which the hardware error indicated. cleaned each connector with compressed air.

after all has been said and done still the same issue + one new one, now there is no sound! LOL! the joy of it all!

help me obi wan......

I want to add that the symptoms that the game is experiencing is that on the high score screen upon startup it is semi-flickering, and once it attempts to go to the "Star Wars" title crawl the game literally appears as if it is attempting to advance 1 frame at a time, with the lines which make up the words "Star Wars" appearing as if they are a bunch of disjointed pieces. what is this exactly? any other tests, or do I need to replace the AVG board?

I've cleaned the fingers with an eraser and removed all the film both sides. Any way to test the interconnect board? or at least clean the interconnect board? what do you recommend to do at this point?

thanks for the help!
