   You are remembering things correctly, Warner. There are two ways to
expand memory on a 100A -- the first is with a "memory option" which
limits you as noted above; the second is with a "memory adaptor option"
along with a "memory module". The methods are incompatible with each
other. [There may have been other methods too; eg,  using an 8087
board, a board from SS... but I'm not familiar with them.]

   The post I had responded to wanted to expand memory cheaply on his
100A. He appears to say 256K would be enough. In that case I suspect
the first approach will be the cheapest as many folks in the past have
upgraded their 100As to 832K from 256K and  thus have basically useless
"memory options".
