Actually the original PC came with as little as 16K with a max of 64K on the mother board and I think you could only go to 256K total. Remember, when the PC came out a BIG pc had 64K. Even huge mainframes of 1982 were in the 16MB range. Also, I think a 64K memory card for the original PC cost something like $500. -- Tom Thackrey sun!amdahl!tat00 [ The opinions expressed herin are mine alone. ]
