Space Duel repair

Hello Group,

Working om my Space Duel, I find the game running blind. In test mode, it
beeps for an error on the AVG RAM and both ROMS. (low - low - high - high -
continous low). I don't have a 6502 pod for my 9010 to make it a little more
challenging.
All address and data lines are alive, as well as the datalines, R/W, /VMEM
and the chip select signals for these RAM / ROMS. The first AVG RAM 2114
couple has been replaced as well. They all seem in order, but I cannot get
the board through self test. I was thinking that the previously mentioned
signals are all that is needed for the uP to be able to access the vector
RAM. Am I right?

I am also suspecting the AVG chip as the addres lines going to and coming
from it are dead. Will the game play blind as mine does when the AVG chip is
dead?

I hope someone can help me out, I'm pretty stuck here... :(

Cheers,

Mendel
