I find the chart rather strange for several reasons.
1. In 1957 transistors an vacuum tubes were used for registers; transistors
were
far too expensive to be relevant to memory prices.
2. No pricing for delay line (used through the IBM 2848) and
drum ((IBM 650, RR Solid State 80/90) memory.
3. No pricing for core on IBM 700 or 7000 series machines
4 No pricing for other magnetic memory, e.g., rod, thin film
5. No memory pricing for any of the 7 dwarves (BUNCH, RCA and General
Electric),
Bendix, Data General, DEC, PB, Philco, SDS, Sylvania, TRW or the major
European manufacturers.
6. No pricing of core or semiconductor memory for most models of the S/370,
including the initial lineup
