You guessed.  I asked Aerco at one point.  They said they could FAX me the
instructions and that it required trace cutting.  That first bank is designed
for 256K DRAMs, which aren't pin compatible with 1M DRAMS.  They said that the
trace cutting necessary was to rewire each socket in some special way.
