I need help identifying a DRAM.  According to the local IBM clone store, it
is a 256Kx4 80 ns DRAM.  I need to know whether it is CMOS or NMOS, or at
least who the manufacturer is, so I can call them.  The runes on the chip are:

  AAAIM304P-08
  NMBS    9051

(The I's might possibly be 1's and v.v.)  I could not find the answer in the
MIT engineering library, so I though I'd ask the People Who Know.

Thanks for your help!      rjw@space.mit.edu
