Battlezone ram errors, rom selection??? Please help

Hello,

     Please help if you can. I'm trying to fix a BZ boardset. I'm getting
what would seem to be ram errors for the 2114's at location A1 and A2. (two
short low tones, followed by two long high tones. Board will not boot,
nothing on screen).
    I've allready installed sockets and replaced the 2114's, and am still
getting the same error. I haven't had a chance to check the enable line for
this Vram pair to see if it is low yet, but I've got a question about the
roms.
    This board has all roms, except for one Eprom located at A3. The eprom
is labled 036421. However, there are no solder pads connected for the rom
selections on this board. Does anybody know what solder pads have to be
connected if you want to put 2716's in the BZ board? Can I replace all the
roms with newly burned 2716's?? What changes do I have to do to the pads?

Any help would be appreciated,

Thanks Very Much,
Michael Kelley
