 IBM proposed a modified S/360 that would include a virtual memory device called the "Blaauw Box" – a component that had been designed for, but not included in, the S/360.The MIT team rejected IBM's proposal.The modified S/360 was seen as too different from the rest of the S/360 line; MIT did not want to use a customized or special-purpose computer for MULTICS, but sought hardware that would be widely available.
