VECTOR: Space Wars Rom Problems

Gang,

My earlier post didn't come back to me so I don't know whether you got it or
not however...

Fixing my Space Wars one rom had most data lines held low - the second rom was fine.

I burnt two 2716's and fitted them in sockets. However now neither rom has
data lines working... in fact no signal on them at all. Address lines are fine.

I have a feeling this is to do with the fact that they were masked roms, but I
had no trouble replacing masked roms with 2716's before.

Any idea how to get the roms to run?

Thanks
Paul
