Sadly, P1 is set in the 1970s and has figures appropriate for IBM systems of that era. Near the end, an experimental cryogenic memory system is attached: * Testing indicated that the results of a live experi­ment would be a data storage unit with 87 percent addressability and sufficient structural integrity to allow a map of the "dead" areas to be constructed. The interface being designed to link the cryos­tat to the 360/50 was geared to address just over 16 million bytes. It was understood that this capabil­ity would grossly understate the estimated final capacity of the cryogen. Modifications were under way to add eight more addressing bits to the computer. This would allow it to address over 4xl0^9 separate locations, or in excess of 4 billion addresses. This was expected to be more in keeping with the ultimate capacity of the cryogen at 150 millimeters diameter by 400 millimeters high. A six-inch cylinder, sixteen inches tall. * The System/360 series started with 24 bits of addressing and moved to 32 bits later on, so we're looking at a whopping 4GB. Even if the storage system uses 32 bit words, that's just 16GB.
